[Iron Horse]

A couple of things with migs . 1 , If you pull the trigger with slag shorting across from the tip to the nozzle the mig wire in the liner will heat up red hot . If you have a nylon liner the wire will melt into it and cause tracks to form . These tracks will cause the wire to jam and shudder and give you trouble . Sometimes it can melt right through the liner and cause gas leakage . 2 , It is important to keep the wire from rusting . I cover my reel with a heavy cloth and i also put a piece of soft cloth on the welding wire just before it goes into feeder tube in front of the pinch rollers and hold it on with a cloths peg . This wipes off any rust particles as the wire is fed into the liner which in turn keeps the liner clean .
