Why Is My MIG Welder Popping and How To Fix It
Why Do MIG Welders Pop The main reason your MIG welder will pop is that your wire speed is either to slow or to fast. To test this simply hold your welder up to a piece of metal you are trying to weld. Hold the trigger and if the welder makes a loud popping noise and tries to push the gun back it means the wire speed is not set right and needs to be adjusted.

MIG Welding: Setting the Correct Parameters
29/4/2020· Wire feed speed/amperage too high: Setting the wire feed speed or amperage too high (depending on what type of machine you''re using) can cause poor arc starts, and lead to an excessively wide weld bead, burn-through, excessive spatter and poor penetration.
Wire-feeding issues are some of the most common complaints in the welding industry. Often, improper trimming or installation of the MIG gun liner is the cause of these problems. As with other consumables, the MIG gun liner wears out over time and must be changed periodically.
