Top value MIG welders in Ireland with weldingsuppliesdirect.ie? How to pick a welder tips: Fan on demand: Lowers running costs and reduces contamination to internal components. The fan kicks in when it’s needed, rather than running all day. Printed Circuit board protection: If the machine’s PCB’s are protected from dust & kept away from the fan, reliability will increase. Some manufacturers’ have the parts that need cooling in a duct type housing & the PCB isolated separately. Step voltage settings: If you’re looking at step voltage conventional MIG with multiple power settings – “the more the better!”
One of the “cardinal sins” that almost every shop commits is over-welding. This means that if the drawing calls for a 1/4″ fillet weld, most shops will put down a 5/16″ weld. The reasons? Either they don’t have a fillet gauge and are not exactly sure of the size of the weld they are producing or they put in some extra to “cover” themselves and make sure there is enough weld metal in place. But, over-welding leads to tremendous consumable waste. Let’s look again at our example. For a 1/4″ fillet weld, the typical operator will use .129 lbs. per foot of weld metal. The 5/16″ weld requires .201 lbs. per foot of weld metal – a 56 percent increase in weld volume compared to what is really needed. Plus, you must take into account the additional labor necessary to put down a larger weld. Not only is the company paying for extra, wasted consumable material, a weld with more weld metal is more likely to have warpage and distortion because of the added heat input. It is recommended that every operator be given a fillet gauge to accurately produce the weld specified – and nothing more. In addition, changes in wire diameter may be used to eliminate over-welding.
MIG welders are divided into transformer and inverter models. Briefly, transformer machines feature only mechanical parts that can adjust the output voltage “sequentially” while the unit is off. The output voltage is not stabilised and may decrease under load. Still, a simple design is the main benefit of transformer welders that facilitate their maintenance. Also, they are often cheaper. Inverter MIG welders are fitted with electronics that allow a smooth voltage adjustment, so it isn’t susceptible to drops and does not fall under load. Of course, power is the main feature of any electric tool. As for MIG welders, their power depends on the maximum amperage, more usually, the output range. This range determines the unit’s field of application. Powerful models can be used on small construction sites or in repair shops, while less powerful models are usually used for private needs. For example, the welders of up to 200A are great for home use; the 300A models are suitable for small repair shops, and if you need a high output and continuous work, consider welders over 300A.

The Lincoln EasyMIG 180 is a well-built welder that’s reliable and will serve a range of light fabrication and workshop projects. Its power input is 230V but it doesn’t have the power of the Hobart 190. This is a great entry level 230V welder that will give you quality welds. It won’t tackle thicker metal but this will do the job for most hobby welders. It’s a great choice for a hobbyist if you have a convenient 230V power outlet.
Several advices on welding equipment, MIG and TIG welders, plasma cutters. TIG welding is similar to to a MIG welder as it uses an electric arc in the same was as MIG welding does but differs in a few ways. Instead of a continuous spool of consumable wire, a TIG welder uses long tungsten welding rods that are manually slowly fed into the weld puddle to join the metal. TIG welding requires gas, usually argon, to protect and cool the weld puddle from external contamination. TIG welding is more suited to welding thinner materials such as stainless steel and aluminium as you can get the power down lower to reduce the risk of blow through and can even weld two dissimilar metals. Suitable for tricky welds such as S curves but TIG welders are still capable of welding heavier materials depending on the machine. TIG welding takes more practice that MIG welding as the process is much more manual with controlling the torch, welding rod and gas by hand (and foot for the gas) but once mastered will produce the highest quality welds making it the better choice where perfect, precise welds are required but due to the manual process is the least productive.
USA market dive: Forney Industries is an American company that was founded in 1932. Forney’s 309 140 is affordable and able to weld many metals. As you’ll see below, its duty cycle is hardier than most, so you can work for much longer without breaks. It is about the same price is the Hobart 500559 Handler 140, but you’ll that the Forney is less suitable for any heavy-duty welding projects you might want to commit to. Therefore, the Forney is ideal for household use, provided that the use isn’t too demanding. It welds up to ¼ inches and includes flux core. It is capable of welding mild steel, stainless steel, aluminum, and cast iron. The Forney is able to use 4 inch and 8 inch wire spools. The cast aluminum wire feeding system ensures that the wire won’t tangle as much while it’s fed through. See more info on https://www.weldingsuppliesdirect.ie/.
