Welding torches must match the performance of your mig welding machine.
The Mig welding torch is characterized by its maximum power amperage & duty cycle, but also the availability of accessories and consumables in relation to the section of the wire used.
Craftsman, coachbuilder or handyman,normally use a basic style of wire for everyday common welding with solid wire from 0.6 mm to 1 mm and fluxed cored wire 0.9 mm will be perfect.
This style makes it possible to carry out welding on thin steel such as exhaust pipe. Although the mig welding gun must cover the min and max range of welding amperage , it is best to choose a light and handy model for lighter welding projects.
The boilermaker, steel fabricator and the welder might need a more powerful mig welding gun allowing the welding of wire from 2 to 3 mm.
The ergonomics of the mig welder handpiece are different from one model to another. Try to determine which mig welding torch is best for your welding position.
