Hi guys, my Lincoln 180 spool gun keeps burning through aluminum with 0.035-inch wire at 20 CFH argon, And it is leaving holes in thin sheets. Any solutions?

try a C25 gas mix to control heat, set wire feed to 210 ipm, And check the ground clamp. clean the contact tip regular to avoid issues.

burn-through is from too much heat. Use 0.030-inch wire for less heat, set voltage to 15V, and do short welds to manage heat. check argon at 22 CFH, And clamp material tight. this stops holes in aluminum.

Lower amps to 80, it helps reduce burn-through on aluminum.
