To all community members, losing patience cause my Lincoln PowerMIG 350 arc sputters on steel, Using 0.035-inch wire at 24V, and welds looks irregular. Can you give me a solution to this?

irregular welds comes from dirty steel surfaces, Clean with acetone thorough before welding, My Lincoln welds smooth now, Check gas flow consistency.

Sputtering comes from poor gas flow or settings, Check for leaks at 20 CFH argon, My PowerMIG 350 sputtered too, Clean steel with alcohol, Set wire speed to 240 ipm, Use 20V for stability, Tighten connections, Ensure proper ground clamp.

Try higher gas flow, it stabilizes arc.

Low voltage causes sputtering, Increase to 24V.
