MIG welding (metal inert gas welding) is a popular form of welding, owing largely to its versatility. MIG welding is suitable for a cross-section of metals, including mild steel, stainless steel and carbon steel, plus aluminium, copper and many more. To MIG weld, you need a MIG welder with good power supply and a good welding torch, MIG welding wire, shielding gas and the material you want to weld, which is often held in place using a welding clamp. The quality of the MIG welding machine, MIG torch and MIG wire is important, so choosing a reputable welding equipment and supplies store like Engweld is essential. There are many different attributes to look out for when choosing your MIG welder, with some having advantages and disadvantages compared to others.
MIG welders are one of our real specialities here at Engweld, having supplied these quality MIG welding machines to many industries over the last few decades. We have the perfect MIG welder to suit everyone, from those working in large industrial environments to hobbyists working on metal at home or in the garage. Our collection includes both gasless and gas MIG welders, plus variations in terms of cooling systems, with air cooled and water cooled the two most commonly found. Then there is of course the choice of power supply, with our extensive range including a host of single-phase and 3-phase MIG welders capable of welding materials of varying thickness. You'll need to see what Amp plug you will be attaching your welder to and what current range each MIG welder works within before choosing which is right for your process.
Because we cater for all, our MIG welder category includes everything from the very best MIG welding machines on the market, suitable for professional welding environments, right down to a selection of cheaper welders suitable for DIYers, but still offering the kind of controls needed to achieve a good weld every time at home. Our most expensive MIG welders generally offer more features aimed at weld precision and operator comfort. You'll see welders with high wire feed speed and good quality wire feed mechanisms, which help with easy welding over a long period of time, while top-of-the-range MIG welders also have a higher duty cycle - another important consideration. With the the best MIG welders, you'll also have the functionality to input material type and thickness, letting the machine know which material you are welding, which should help achieve a better weld.
Often, the biggest decision when considering purchase of a MIG welder is whether to go for a gasless or gas MIG welder. Both have their pros and cons, so it's important to be informed and understand which is best for different MIG welding processes. Gas MIG welders use shielding gas (hence the name) and generally achieve a better weld quality overall with less spatter. The shielding gas makes the arc plasma and stabilises it on the metal that is being welded, which heats the two pieces of metal and causes them to melt and join. In contrast, gasless MIG welding machines require flux cored wire and operate similar to Arc welders or stick welders. This flux cored wire burns very hot and can often cause weld spatter and gasless MIG welding is only appropriate for thick metals. For the most part, utilising a gas MIG welder is recommended and easier.
Other features and considerations you may want to look out for when perusing our selection of MIG welders include voltage steps and polarity. Voltage steps refers to the increments in which you can change the voltage on your welding machine. Cheaper MIG welders will have harsher voltage steps, whereas more advanced machines allow for more precision with regards to voltage. Polarity, meanwhile, can be either straight or reverse, with the former focusses more heat on the MIG wire and the latter focussing more heat on the materials being welded. In almost all cases, reverse polarity is recommended and the vast majority of MIG welding machines use this polarity.
You can rest assured knowing that any MIG welder bought from Engweld is of a guaranteed high quality, thanks to the experienced manufacturers we work with. In our collection, you will find MIG welding machines from the likes of ESAB, Lincoln Electric, Migatronic and Parweld, all of whom bring their immense expertise to the welders on offer. Each brand offers different features, so it's always a good idea to read the detailed individual product descriptions before purchase.

Our selection tool is the best way to easily find the right shielding gas every time.
For the most part, gas metal arc welding (GMAW) produces superio welds with minimal spatter. Gasless metal arc welding (GMAW-C), which employs flux Cored Wire, operates similarly to stick welding. This wire burns intensely, generating significant amounts of spatter.
Due to the high heat output of flux-cored wire, gasless MIG welders are unsuitable for welding thin materials, such as those used in automotive bodywork. While gasless MIG welders have their specific applications, we generally recommend using a gas metal arc welder whenever possible and that's why our collection is largely focussed on high-quality gas MIG welding machines from leading manufacturers.
