What is MIG welder?

The full meaning of MIG welder is Metal Inert Gas welding. Most of the American people call MIG welder as Gas Metal Arc Welding or GMAW. And the professional workers like to call this machine Wire Welding.

MIG welder uses a thin wire to do weld on metal. The thin wire works as a consumable electrode and heats the metal to join. You can use solid wire for gas shield welding and flux-core wire for gasless welding. In both processes, the MIG welder heats both metals and melt them to join together. The wire comes from MIG spool through a tube and comes out from MIG gun to do weld.

The direct current flow is best for good quality welding. If you cannot find a direct current source, then you can use a secondary power source to do welding. The modern MIG welder comes with advanced IGBT inverter technology, that’s help, you to weld in different modes. For this function, you can use the MIG welder as a Stick Arc welder and Lift TIG welder.

How to Use of a MIG Welder? 

It is always essential to learn how to use the machine before work. If you do not know anything about the device you are using, you can damage the machine or the materials you are working on. You can also end up in a hospital for not knowing the proper way of using the device. The MIG welder uses current flow to do weld. So you must make sure all safety before do welding.

If you stay with me and send some time on this article, then I hope you can find out how to use a MIG welder. Even you are a newbie, and you will have an idea to work with MIG welder.

MIG welder control systems

The main part of the MIG welder is control systems. Without knowing the control systems, you cannot use a MIG welder to do weld.

And Arc controller knobs that help the welder to maintain the heat. It also has a wire feed controller that helps wire-speed comes through the MIG gun. If you can control this function, then you can start to do welding.

The right way to hold a MIG Torch

Another important thing is the right way to hold the MIG torch. If you hold the MIG torch wrong way, then you cannot get a perfect welding result. The ideal welding result depends on the way we use the MIG torch and the MIG gun. For getting good weld to use your one hand to hold the MIG torch and use another hand to hold the MIG gun. The perfect distance between the metal and the torch also counts for the good weld.

Overlook the welding area

It is good practice to overlook the welding area every time you do weld. Because you need to check the weld is perfect or not. If you think that you are not getting your wanted welding result, then change the control and try again. You can different welding results only by changing the Arc controller and wire feed speed control.
