The Work Process of MIG Welding

 The Work Process of MIG Welding 


The Work Process of MIG Welding
A mig welder runs off electricity and uses the electrical current to improve the temperature with the base metal and fuse the filler metal (MIG wire) together within an electrical arc. This is your welding process.

The electrical current is passed through the power point for the wall, in to the welding strength, with the welding torch. When the trigger is squeezed the existing then travels over the contact tip into the wire making the welding wire live and conductive.

On the part you want weld, you attach the "welding earth" lead. Then when the MIG wire touches the earthed part, the electrical circuit is complete. As a result, the electricity starts to flow making a flash of sparks and an arc is created.

This arc is welding, without it you have nothing. Remember that "arc welding" is the process of welding using electricity. Mig welding is still arc welding as it uses electricity to make an arc, it's just that we call it MIG welding.
