To all community members, at my wit is end cause my Millermatic 252 arc sputters on steel, Using 0.035-inch wire at 22V, and welds looks irregular. How i can avoid this problem?
Sputtering comes from poor gas flow or settings, Check for leaks at 20 CFH argon, My Millermatic 252 sputtered too, Clean steel with alcohol, Set wire speed to 240 ipm, Use 20V for stability, Tighten connections, Ensure proper ground clamp.
irregular welds comes from dirty steel surfaces, Degrease with acetone thorough before welding, My Miller welds smooth now, Check gas flow consistency.
