MIG welding guns feed the wire and conduct electricity to the weld. In most MIG guns, the components can be changed, in the case of a problem or breakage. The parts of a MIG welding gun include:
* The nozzle is the cylindrical shaped portion of the MIG gun that contains the tip.
* The nozzle directs protective gases that flow through the line onto the weld during welding.
* When the trigger is pulled, the feeder wheel inside the welder spins, which pushes the wire out and causes the weld arc.
* The handle of a MIG gun is the large area that is intended for holding.
* Inside the MIG gun resides the lining that the wire slides through.

Select the Right Amperage:
Selecting the lightest, most flexible MIG gun for the application is the best choice. In the case of a 400-amp application, a MIG gun rated at 300 amps may suffice.
Getting a handle on the selection:
Another important factor in maintaining a good comfort level for the welding operator is selecting a MIG gun with the appropriate handle, neck and cables for the application.
Staying cool:
There are two main types of heat in a welding operation: radiant heat from the arc and resistive heat from the cable. To protect against both types of heat, it is important to always wear proper protective apparel, including a helmet, welding gloves and a welding jacket or sleeves. Radiant heat is heat that reflects from the welding arc and base metal to the handle. If the welding operator welds on shiny materials, such as aluminum or stainless steel, it will likely reflect more heat that a duller mild steel. Using a longer neck to the MIG gun can protect the welding operator from radiant heat by placing the handle further back from the arc. Since the neck can also carry heat to the handle, it is important to use front-end consumables-nozzles, contact tips and diffusers that remain cool.
Putting it all together:
When selecting a MIG gun for any application, the goal is twofold: to have the right equipment for the application and to keep the welding operator as comfortable as possible. Also by taking precautions against heat exposure, a welding operator can ensure that he or she will be able to complete the required welds with minimal discomfort. [Collapse...]
