Mig welding is the choice of most Collision repair shops today. Mig welding really took hold in the mid 1970 in the repair industry. Mig is a abbreviation for Metal Inert Gas Welding. Mig welders consist of a handle with a trigger controlling a wire feed, feeding the wire from a spool to the weld joint. The wire runs through a liner which also has a gas feeding through to the point of the contact Arc. The gas surrounds the Arc protecting it from the outside air. This helps the welding area to recieve the perfect enviroment for a perfect weld.
Mig welding requires three things, electricity to produce heat, An electrode to fill the needed weld joint, and a shielding gas to protect the weld from the air.
When you adjust your welder to the perfect welding speed, temp and gas output it will sound similar to hot frying bacon a fast crackling sound.
