Who would benefit from a MIG welder?

Most professional welders have a MIG welder on hand for use on several different projects. MIG welders are definitely user-friendly for first-time welders, and they can be used for numerous projects. If you’re into automotive repair, have your own welding workshop, or are just looking for a simple way to join metal together, then a MIG welder can be your best friend.

What to look for in a MIG welder

Before you purchase a MIG welder, there are several things to take into account. In this article, we’ll try and help you in your purchase decision by providing the most important specs to consider when searching the market for an ideal MIG welder.

Gas or Gasless

MIG welders require a shielding gas to prevent oxygen from ruining the welding process. The two choices you have are gas-shielded (usually an argon and carbon dioxide mixture) or flux-corded wire (the wire itself contains a compound which emits a protective layer of gas). Both of these methods have their own set of pros and cons, but generally speaking, gas-shielded produces much neater results. If you’re unsure which to use, the safest bet is to choose a MIG welder that can do both.

Amperage and Metal Thickness

The question “What metal thickness can a unit weld?” refers to the thickness of metal which can be welded together with a single pass while reaching complete and thorough penetration. The consensus is that for steel, any unit below 140 amps is best for sheet metal, a 140-amp unit can do ¼-inch, a 180-amp can do any thickness up to 5/16-inch, a 200-amp is best suited for thicknesses between 3/8-inch and 5/16-inch, and a 250-amp can reach up to ½-inch.

Weight and Portability

Welding is a tricky task, especially if you need to maneuver your body and the welder to get into a proper position to do it. Though portability may not be your highest concern, it’s definitely something to take into consideration, especially when working overhead and traveling vertically. Another feature that adds (or reduces) the portability of a MIG welder is whether it comes with an inverter which allows it to be plugged into portable generators.

Duty Cycle

The duty cycle lets users know how long they can run the welder before it begins to overheat. The duty cycle is conveyed by a percentage and at how many amps. For instance, say a machine has a 20% duty cycle at 90 amps. This expression shows that within a 10-minute window, the welding machine can be operated for 2 minutes at 90 amps and needs to be rested for 8 minutes before beginning again.

Thermal Overload Protection

Thermal overload protection serves to keep your machine running for several years by preventing the unit from overheating and causing long-term damage. Though the intention of this feature is noble, not many welders have a properly-working protection mechanism in place. Be sure to check out MIG welder reviews to see if that specific device has any glitches in its thermal overload protection system.

What MIG welder works best?

Hopefully, by now, you’re a bit more familiar with the welding process. Let’s take a look at some of our recommendation for best MIG welders that will help you in becoming a welder expert.

Conclusion

Any person can benefit from a MIG welder, whether they’re just starting to get into the game or have been doing it for several years. MIG welders are mainly used on steel, stainless steel, and aluminum alloy.

In this article, we’ve explained the five major points of consideration before purchasing a MIG welder, namely whether the unit uses gas (MIG) or whether the gas is emitted via the wire during the welding process (flux-cored wires), the amperage capacity and the required amps needed to penetrate fully and thoroughly into certain metal thicknesses.
