This is driving me nuts cause my Esab Rebel 235 welds has porous spots on steel, Using 0.035-inch wire at 22V, and welds shows bubbles. Can you give me a solution to this?

Porosity comes from dirty steel or gas issues, Clean with acetone thorough before welding, My Esab Rebel had bubbly welds too, Use 25 CFH argon for better coverage, Check gas hose for leaks, Set wire speed to 240 ipm for consistency, Use 7018 electrodes for cleaner welds, Ensure clean joint fit-up, Use wire brush for prep, Verify regulator settings.

bubbly welds comes from dirty surfaces, Degrease with alcohol thorough before welding, My Esab welds clean now, Check gas flow for consistency.

Increase gas flow to reduce porosity, it helps.

Use fresh wire to avoid bubbles, My Esab got better after switching, Check connections.
