This is killing me cause my Hobart Handler 190 burns through thin steel, Using 0.030-inch wire at 22V, and welds has holes. any fixes?

Holes comes from too much heat on thin steel, Set Handler 190 to 18V for better control, My Hobart burned through too, Use 0.030-inch wire for thinner sections, Clean with alcohol before welding, Set wire speed to 220 ipm for stability, Use 20 CFH argon for coverage, Use pulse mode if available, Ensure clean joint fit-up, Check ground clamp condition.

burn-through comes from high heat settings, Lower to 16V for better control, My Hobart welds thin steel smooth now, Clean with acetone thorough.

Use pulse mode for thin steel, it helps.

Use 0.025-inch wire for better control, My Hobart welds got better, Clean thorough.
