Mig Welder Gun Tips and Where To Buy Mig Welding Torch Parts!

A Mig welder gun is the most important part of your welding kit. Any Mig welder will know that you cannot carry out any Mig welding function without a Mig welder torch. The torch is the final piece of equipment that completes the welding set and allows you to carry out your welding needs.

Older welding types don't have a torch like a Mig welder, so it may come as a surprise that a mig welder gun is one of the most basic pieces of equipment for a Mig welder to have.

While understanding the importance of a Mig welder gun is great, one of the questions many people ask about the Mig welder torch is how does the torch work? Today we will explain what a Mig welder torch is and how the torch works, including the design and functions of use.

A Mig welder gun has all the usual equipment of other welders, such as an earth clamp and cable, but it also has a specially designed arced torch with a trigger on its underside. The torch allows for the semi automatic process in Mig welding, making it easier for the welder to carry out his work.

Once the welder is ready to start work, he or she will bring the torch down close to the metal they wish to weld. The welder will then press the trigger on the underside of the torch, keeping applied pressure for as long as they require. By pressing the trigger the torch will feed welding wire from the welder down onto the metal being welded and also release shielding gas.

The Mig welder always has the arc ignited so once the welding wire comes out of the torch and close to the metal being worked an arc will form.

The torch is found on the end of the protective torch cable, this cable carries the welding wire, electric current and shielding gas.

Within the handle of the mig welder gun, known as the torch body, there are two pipes. One of the pipes is small and this pipe carries the shielding gas, the second pipe is wider and feeds the filler wire through the torch. The torch trigger is attached to both pipes and does not allow either the wire or shielding gas to feed through their pipes unless pressed.

At the end of the torch body there is an insulated neck that is arced and carries the filler wire and shielding gas pipes to the nozzle at the end. The nozzle is metal and is larger than the insulated neck in circumference. The nozzle contains a contact tip and provides the electrical connection to the filler wire.
