Span gas online supplier UK: Shielding Gas for Gas Metal Arc Welding: For GMAW the additions of helium range from around 25% helium up to 75% helium in argon. By adjusting the composition of the shielding gas, we can influence the distribution of heat to the weld. This, in turn, can influence the shape of the weld metal cross section and the speed of welding. The increase in welding speed can be substantial, and as labor costs make up a considerable amount of our overall welding costs, this can relate to a potential for significant savings. The weld metal cross section can also be of some consequence in certain applications.

Overall, argon is a standard, low cost but high-quality choice of shielding to use when welding. Although its odourless and colourless properties make it a convenient gas to use, it can also be dangerous if leaks or overexposure when welding occurs. Never forget that you are dealing with a potentially hazardous element, so entrust installation to a specialist gas installer who knows what they are doing.

WSD (weldingsuppliesdirect.co.uk) supplies a wide range of shielding gases specifically designed to optimise performance in particular conditions. In vehicle repair and manufacturing, argon-based gas mixtures are commonly used to MIG weld carbon and low alloy steels. Argoshield Light is one of those choices. It’s ideal if you are welding thinner carbon steel ranging from 0.6 to 5mm in thickness. The addition of oxygen to Argoshield increases arc stability to minimise spatter and fast weld speeds with its low heat input reduce distortion. So it’s perfect for our earlier example where the components of a car are being painted or powder coated after welding. See more details at Span Gas Bottle.

The primary task of a shielding gas is to protect the weld pool from the influence of the atmosphere, i.e. from oxidation and nitrogen absorption, and to stabilize the electric arc. The choice of shielding gas can also influence the characteristics of the weld penetration profile. The basic gas for MIG/MAG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades. However, small additions of oxygen (O2) or carbon dioxide (CO2) are usually needed to stabilize the arc, improve the fluidity and improve the quality of the weld deposit. For stainless steels there are also gases available containing small amounts of hydrogen (H2). Calibration gases are split into two categories. These are zero calibration gas and span calibration gas. Calibration gas is used to calibrate gas analyser’s. Calibration gas is in addition used to calibrate Gas detectors. These Gases will also be known as Span Gas and come in a Span Gas cylinder. This product has added one or more component(s).

Nitric oxide (NO) and nitrogen dioxide (NO2 ) are known collectively as nitrous gases (NOx). They can be generated by oxidation of nitrogen in the air by heat from an arc or flame. Chemical Hazard Alert Notices (CHANs) were issued in UK in 2003, withdrawing the exposure limits of NO and NO2 because they were not considered to be adequate to protect occupational health. New exposure limits of 1ppm 8-hour TWA have been recommended for each gas. Source: weldingsuppliesdirect.co.uk.

Top China industrial manufacturers shopping reviews? Beijing holds its industrial power due to its sister city, Tianjin, which itself is another manufacturing giant. This city is a leader in aerospace and aviation, mobile phones, automobiles, and alternative energy products.

China is the fourth largest oil producer in the world with the country having a production of 1.3 billion barrels in 2002. The size of oil deposits in China is not known for numerous oil exploration studies being conducted in the country. Despite China’s enormous oil production, the country is still oil-deficient and being the world’s largest oil consumer in the world, and the country relies on oil imports to meet its domestic oil demand. China has also invested in renewable energy which is seen as the new frontier in the energy industry, with the country being the top electricity producer from renewable sources. The country has numerous wind farms located in its vast territory as well as in offshore sites to harness wind energy which according to researchers from Tsinghua University, can meet the country’s electricity needs.

What’s Virtual Reality gaming, is it safe for my kids, read on to get clear picture. The minimum age limitation for VR gaming is 7+ but most of the headset manufacturers’ set the age limit according to their hardware. SONY’s play station VR has restricted the age limit 12. Oculus Rift and Samsung’s Gear VR rate it of 13+. Only HTC has no specific age restrictions but it also warns its use for children.

What VR games can you play ? Beat Saber is a music and rhythm game with an active twist. The setup is similar to other music games, such as Audiosurf, Guitar Hero, and Rock Band, but instead of controlling a virtual ship or using fake instruments, you slash your way through a song with virtual laser swords. As the music plays, Beat Saber generates different patterns of color-coded blocks on the screen that you must hit with the correct controller (right or left) as they slide towards you. Obstacles also appear at times that require you to duck or slide away. Make no mistake, Beat Saber is not a game you can play sitting down; it’s a very active experience. If you love music and motion, Beat Saber is definitely worth exploring. See additional info at Kids activities in Toronto.

VR (virtual reality) gaming is the utilization of a three-dimensional (3-D) created play ground to computer games. Virtual reality environments are created with VR software and presented to the user in such a way that they overlap the real-world space, creating a feeling of mirage and helping the user experience the VR environment as real.

Rotabroach buyer tips: In order to find a worthy investment, one has to get familiar with the do’s and don’ts. However, most people decide to skip that particular step and invest in the first thing they find interesting. Sadly, that strategy usually ends up with you buying something that doesn’t meet your expectations or overpaying something you could get for less money. Either way, it’s essential for every serious buyer to go through some of the tips and tricks of drill shopping in order to get the best possible deal. Keep these tips in mind and you’ll more than likely find a good model for yourself.

At the top of the list is this 10 amp motor drill that has two-speed settings of 300 to 450 revolutions per minute. It has safety features: the overload protection electronics which helps prevent damage to the motor. The chuck system can be easily changed. It is ideal for heavy duty application from the 4 3/8 inches drill travel. Finally, the drills magnetic coolant bottles can be placed on either side of the drill on a work surface to keep the drill from overheating.

Magnetic drill press is very compact. In some case, it is also lightweight. For personal usage, it is the best option, and some of the mag drills so likely are usable for the industrial application. For your convenience, here ten top rated magnetic drill machines are reviewed. Let’s go through the reviews and pick the best one which satisfies your requirements. A magnetic drill press or mag drill press or magnetic drill is a specialized drill press that is designed for drilling holes in metal or wood. During working, Magnetic drill press must magnetize to a solid surface. Magnetic strength is undoubtedly related to steel thickness. Minimum thickness of the steel plate is 3/8 inch. See extra details on Mag Drills.

DeWalt dwe1622k magnetic drill press is the best magnetic drill machine for the money available in the market. They improved the drill press through several developments that make the drill press a position on DIY expert workshop. This drill press is a perfect drill press not only for its perfection but also for its unique feature to satisfy your requirement. It is provided with feeding handle that can be easily installed any side of the drill press. For optimal performance and variety of applications, this excellent mag drill press featured with two-speed setting and 10 amp motor which make this drill press a metal or wood drilling breeze. This excellent mag drill package includes the magnetic coolant bottle that protects your drill press from overheat. It can be fitted on either side of the drill press.

Although this is a regular drill press and not a magnetic drill press, you can also use this one for steel drilling. The motor has a rating of ½ HP and in order to change the drill speed for metal drilling, you have to change the belt and pulley combination setting to the slowest speed. As a drill press, the RIKON 30-120 does not have the best performance. The feeding wheel is not well made and is awkwardly situated. Your chances of getting the back of your fingers caught between the feeding wheel and the belt tensioner are quite high and it is very painful. The packaging of this drill press is poor as well. If you are looking for a tool that you can use for drilling steel exclusively, we recommend that you stick to magnetic drill presses. Regular drill presses can work great for wood, plastics, and steel, but they don’t have magnets and is impossible to use for vertical and overhead applications.

Some MIG welding machines handbook: how to become a better welder and how to choose the top welding equipment. All welding requires the application of heat, which melts the metal being welded. With the TIG process, the heat comes from an electric arc that streams between the electrode in a hand-held torch and the metal being welded. The arc and molten metal are shielded by an inert gas, which protects the electrode and base metal from oxidizing. Filler rod is usually added to the puddle of molten metal as the weld progresses. The essence of making a good weld is heat control, which is governed by how you modulate the arc as it streams from the torch. Let’s look at this in detail.

Delivery of parts to the welding station in an organized and logical fashion is also a way to reduce welding costs. For example, one company was manufacturing concrete mixing drums. In the fabrication process, the company produced 10 parts for one section, then went on to make 10 parts of another drum section, etc. As pieces came off the line, they were put onto the floor of the shop. When it was time to weld, the operator had to hunt for the pieces needed and sort through them. When the outside welding expert pointed out the amount of time being wasted in this process, the company started to batch each one on a cart. In this way, the pieces needed to weld one drum were stored together and could easily be moved to the welding area. This type of scenario is also true for companies that may outsource parts to a vendor. Though it may cost more to have parts delivered in batches, it may save more in time than having to organize and search through parts to be able to get to the welding stage. How many times each piece is handled in the shop may be an eye-opener to reducing wasted time. To measure such an intangible as this, operators are asked to put a soapstone mark on the piece each time it is touched – some companies are surprised to find out how many times a part is picked up, transported and laid down in the manufacturing process. In the case of one company, moving the welding shop closer to the heat treatment station eliminated four extra times that the part was handled. Basically, handling a part as few times as possible and creating a more efficient production line or work cell will reduce overall costs.

A few tips about welding equipment, MIG and TIG welders, plasma cutters. What factors should you consider when determining a budget? You may already have an estimated budget in mind. The type of welder you purchase should be suited for the specific functions you require as well as the projects you will work on the most. Think about your end goal and consider opportunities to expand the usefulness of your welder. Will you want more power or amperage in the future? It is important to take note of the varying amperage and power requirements as well as the duty cycle necessary to achieve the most effective and economical operational results for the projects you’re looking to complete. In addition to the cost of the welder itself, don’t forget to include costs for the accessories and supplies you’ll need to operate your new welder. This includes welding protection (helmet, gloves, jacket, etc.) as well as gas and consumables.

Welding faster may sound appealing, but aside from practice, there are few shortcuts when creating a strong weld. In fact, unless a situation calls for a fast-moving weld, there’s a good chance that slow and steady is the way to go. An online search for ways to weld faster, will yield either descriptions of the ways automated welding has increased welding speed or press releases from companies who claim their gas or electrode holds the key to improving welding speed. In other words, it can seem like spending a lot of money is the only way to weld faster. However, for those looking for some ways to save time on their welding projects, there are some ways to weld faster for certain projects. While it’s not always a good idea to find a way to weld faster, there are situations when welding faster may produce a better product or a few simple changes can speed up the time on task. Find additional info on MIG welders.

And another tip is use the old school type of collet body(not gas lens) and one size smaller cup than you would use for steel that still provides good shielding. A smaller old school (not gas lens) TIG cup confines the shielding gas envelope to the puddle so that arc energy is not wasted in the form of frosty cleaning action outside the weld. A lot of Old timers use the small cups, they just don’t know why. Pay attention next time you weld aluminum and use a small cup and then turn the shielding gas flow down to around 12-15 cfh with a #6 cup and see if things don’t quiet down a bit.

Searching to purchase some top quality flexible metal conduit? Here are some tips and extra details helping you to make the best pick.

As our experience, there are several factors you need to take into consideration. Be sure to look at all available wires and cables when determining what conduit is best for your application. There are two kinds of flexible conduit, plastic flexible conduit and flexible metal conduit. Be sure to use the correct flexible conduit for job at hand. The flexible conduit fill is the maximum amount of space that the conductors running through the conduit can occupy. This would be your most important factor in determining the conduit to choose for a job.

The most common type of electrical conduit for house wiring is the thin-wall type. Thin-wall conduit is too thin for threaded joints. It is joined to other lengths of conduit and to boxes by pressure-type fittings. Stainless steel EMT conduit and fittings combine strength with ductility, resulting in an affordable, lightweight and easy-to-handle conduit assembly. EMT can be installed indoors and outdoors in accordance with UL and NEC® requirements. Read more details on Plastic Flexible Conduit.

Flexible metal conduit is best known by its nickname “Greenfield,” for its inventor, Harry Greenfield. It is a spiraling metal tubing that bends easily and is commonly used for short, exposed runs in household circuits, such as connections for garbage disposers, hot water heaters and furnaces. FMC is suitable for dry locations only and must be supported every 4 1/2 feet and within 12 inches of each electrical box. It can be used as a ground path only with approved fittings and only where flexibility is not an issue after it is installed. For example, if it’s connected to a motor that vibrates, the conduit cannot be used for grounding.

The usage of Flexible Cable Conduit is a practical process to be certain the electric wires installed in the home or office receive proper protection. The flexible kind of conduit will be the easiest to use in comparison with alternatives like rigid plastic or metal. The flexible conduit has the down-side of not being so strong and gives less protection. But, for the do-it-yourself enthusiast working in the home, the flexible material is usually favored due to its simplicity.

Flexible metal conduit (FMC) is also called “Greenfield,” after the name of its inventor. It has a spiral construction that makes it flexible so it can snake through walls and other structures. Standard FMC is used in dry indoor locations, often for short runs between a wall box and a motor or fixed appliance, such as a garbage disposer.

CorrugatedConduit.com is a leading supplier of flexible conduit located in Kowloon, China. We have 15 years cooperating qualified manufacturer in mainland. Because of our good quality control management and large volume we are able to sell you the best flexible conduit at competitive prices. Source: https://corrugatedconduit.com/.

Highest value MIG welding equipment online and welding tricks? We have plenty articles on this topic, you can use the search box of this post doesn’t answer your questions.

Gasless welding, which is also called “Gasless” or “No-Gas” welding, is the main convenience of contemporary MIG welders. That means they can make welds either with or without gas. It is possible thanks to the use of a special tubular wire filled with a flux and metal powder called a flux-cored wire. In a nutshell, when a flux-cored wire is used, its components generate a shielding gas under a high temperature that is essential for a high-quality joint. The thermal overload protection is also a useful feature that will switch the unit off automatically if the temperature reaches a certain level. Surely, a MIG welder is not something you will carry every minute. Yet, if a machine is lightweight and fitted with wheels, using it will be much more pleasurable. Finally, pay attention to the kit each tool comes with. Some models include a welding shield, coil, attachment for flux-cored welding, hammer, or brush. So, take these features into account when buying a welder.

How to pick a welder tips: Stepped voltage or synergic: Synergic MIG’s have the edge when you’re welding stainless & aluminium as they are pre-programmed, easy to set up & portable. They also provide a better weld characteristic and so give cleaner weld bead with less/no spatter. Inverters: Considerably smaller and lighter and so ideal for site work. All inverters are stepless and so have infinite control. Also cheaper to run power wise. Budget: How much welding are you going to undertake? Gear your purchasing decision around the jobs you will be working on the most. Polarity changeover; A lot of welders at the light industrial end will to be able weld with gasless flux cored MIG wire. Is the switchover easy on the machine you’re considering. Availability of spares & after sales service: Ask where the machine is actually made. Even the more recognised brands largely outsource their production, which can lead to quality and after sales issues with lack of continuity of supply for spares.

Delivery of parts to the welding station in an organized and logical fashion is also a way to reduce welding costs. For example, one company was manufacturing concrete mixing drums. In the fabrication process, the company produced 10 parts for one section, then went on to make 10 parts of another drum section, etc. As pieces came off the line, they were put onto the floor of the shop.

Several tips on welding equipment, MIG and TIG welders, plasma cutters. MIG Welders are extremely popular because they tend to cost less than TIG or Stick welders with comparable power and features, are extremely easy to learn, and can tackle a wide variety of projects. Since the filler metal is fed through the MIG welding torch, welders can use both hands to hold the torch steady rather than using one hand to add filler metal, as in TIG welding. The wire feeder also makes MIG welding up to four times faster. The MIG welding process uses an inert gas to shield the weld and to keep it free from impurities. This makes MIG welding very neat and easy to clean up since there isn’t anything to chip away, which is typical for Stick welding. MIG welding can be used on a wide variety of materials such as aluminum and is also frequently used for automotive work. However, MIG also requires the purchase of shielding gas and generally requires materials that cost more when compared to other methods. Find more details on MIG Welders Online Shopping.

USA market choice: Miller is a Wisconsin-based company that has been in the business since 1929. At just 38 pounds, the Millermatic is ultra-portable and is one of the lightest welders on our list. It is preferred by amateur welders and professionals alike for its usability. It is also one of the most expensive at over $3300, so bear that in mind as you read on! The Millermatic runs at dual voltage. It welds stainless steel, mild steel, and aluminum (with the help of a spool gun). It can weld mild steel to a thickness of 3/8 inches, giving it greater ability than the Hobart Handler. As for its aluminum welding capabilities, it can weld from 18 gauge to 3/8 inches again. It comes with flux core abilities.

If you’re a beginner welder but don’t mind splashing the cash for a top of the range welder, then try the Millermatic 141. Miller have really pushed the boundaries of usability with this welder and it features an auto-set feature for an easy set up, and infinite voltage and wire speed control. All you have to do is select the thickness of the metal you’re welding and you’re ready to start welding straight away. If you open up the machine you can tell that all the parts are great quality and really durable as well. There are more powerful welders on the market for the price, but there’s nothing better for welding up to 3/16 inch steel. See the full review here.

How to earn money by playing games ? Sounds awesome but this thing really exists ? Yes and i will make an overview of the “play and earn” methods available today and finishing with an InBoxDollars review, a make money from home opportunity platform that also has a gaming section, where you can earn cash by playing games.

Classic “earn money from games” methods are difficult and competition is big. Let’s take for example: Stream your gameplay in real-time for the world to see. Aim to build a large audience (which you can monetize with ads) or a loyal audience (which you can monetize with donations and subscriptions). The biggest platform right now is Twitch, but YouTube Gaming is also an option. It takes a long time to build a live stream audience. You may not break 10 viewers for several months, and you may not reach 100 viewers for years. The reality is that some streamers never reach that point—and to earn a living streaming video games, you’ll need thousands of regular viewers.

Now let’s move with some real make money while gaming method: Sites such as Swagbucks and MyPoints offer their members opportunities to play online games in exchange for points – and these points can then be traded in for gift cards or even Paypal payments! Now, this method often includes spending some money up front: you purchase game tokens at GSN.com (or whatever game site your points club partners with), and earn a certain number of points in exchange. But if you like to play those sorts of online games anyway – games like Super Plunko, Deal or No Deal Slots, and Bejeweled 2 – this can be a good way to turn your enjoyment into a gift card or cash return. And Swagbucks even has some free games on their own site! Read extra details on Make money playing games.

A magnetic drill is a special drill used to cut metals. It is made of four major parts: a drill stand, motor, arbor or chuck, and a magnetic base. Unlike a bench top drill or a standing press drill, the magnetic drill is useful especially in areas that are hard to access like vertical metal parts that are stationary. The other reason why it is the better option is that it gives you precise and speed drilling that is very accurate and consistent. The magnetic base enables it to adhere to carbon steel when it is turned on.

One should also pay attention to the features when buying a mag drill. Some features are essential while others are there to mitigate and alleviate some of the most common hassles people run into. It’s important that you keep an eye on the crucial features and invest in a model that offers quality instead of quantity. While this particular step is purely driven by one’s budget, it’s still important to get familiar with all the aspects of your new power tool.

The swivel base found in this increases its versatility with a precise line up the pilot with the hole center location. It is very ideal for tight areas, overhead and horizontal areas over other steels. Most of its accessories are portable. The feed handles can change direction quickly from left to right and vice versa. For more accuracy, it has a slot drive arbor. When the motor is turned on the power increase by 30% through the 2 stage magnet. It comes with a three-year warranty meaning the manufacturers assures of quality service from this tool. See extra details at Rotabroach bits.

Although this is a regular drill press and not a magnetic drill press, you can also use this one for steel drilling. The motor has a rating of ½ HP and in order to change the drill speed for metal drilling, you have to change the belt and pulley combination setting to the slowest speed. As a drill press, the RIKON 30-120 does not have the best performance. The feeding wheel is not well made and is awkwardly situated. Your chances of getting the back of your fingers caught between the feeding wheel and the belt tensioner are quite high and it is very painful. The packaging of this drill press is poor as well. If you are looking for a tool that you can use for drilling steel exclusively, we recommend that you stick to magnetic drill presses. Regular drill presses can work great for wood, plastics, and steel, but they don’t have magnets and is impossible to use for vertical and overhead applications.

Nova Voyager DVR magnetic drill is one of the very first smart and most featured drill press. This also plugs and play type drill press with advanced direct-drive motor technology and safety sensors. This drill press recognized as the best versatile and well-featured drill press available in the market. It can handle glass, plastics, metal, and wood for any innovative projects. With no load, it can run 50 rpm to 5500 rpm variable forward speed as well as reverse speed.

Applications include attachment of reinforcing braces and stiffeners, functional brackets, hinges and other parts. Often, spot welding is the method of choice for assembly of entire enclosures, cabinets and multipart assemblies. Thickness of the majority of parts joined by spot welding ranges up to 1/8 in. (3 mm) for each member, although parts up to 1/4 in. (6 mm) thick have been successfully spot welded. Based on the experience of stampers and fabricators, certain general recommendations can facilitate spot welding of a sheet metal design, no matter what metalforming process is used to make it. It is always useful to consult with the metalformer in the design stage when questions arise regarding the part design, application of spot welding or, control of spot welding cost for a particular design.

Position the welding torch with the wire in the center of the hole contacting the back sheet of metal. It is important to arc against this back sheet rather than on the edge of the hole, otherwise the weld might not penetrate into the back sheet. The torch should ideally be pointing directly into the hole rather than at the angle in the photograph. Start welding in this position and don’t move the welder until the hole is almost full of weld. Then move the welder outwards in ever increasing circles until the weld is completed.

How Does Spot Welding Work? A form of resistance welding, spot welding is one of the oldest welding processes whereby two or more sheets of metal are welded together without the use of any filler material. The process involves applying pressure and heat to the weld area using shaped alloy copper electrodes which convey an electrical current through the weld pieces. The material melts, fusing the parts together at which point the current is turned off, pressure from the electrodes is maintained and the molten “nugget” solidifies to form the joint. See more details at Tecna Spot Welder Parts.

Electric welding relies on the Joule Effect. This is the thermal result of the electrical resistance, occurring when an electric current passes through a conductive metal – in this case metal sheets for assembly. If that last sentence went over your head, here’s how it works: to weld two or more sheets together without adding a filler metal, they are tightly compressed between two heat-resistant electrodes (i.e. non-melting), generally made of copper, and a high-intensity current is applied to melt the plates together at that point. The result is a small merging of metal which constitutes a welding point. The welding time is very short, between one and two seconds, and the shape of the resulting welding spot depends on your choice of electrodes.
