Why is All community members, my Lincoln Power MIG 215 spool gun burning through with 0.035-inch wire at 90 amps? it is leaving holes in aluminum. Any fixes?

lower amps to 80, It reduces burn-through on aluminum.

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 prevents holes in aluminum.

[David Poole]

use a C25 gas mix for heat control, tack weld first to hold shape, And clean contact tip regular.

Short bursts helps reduce burn-through, it keeps heat in check.
