        i’m a little bit confused cause my Vevor MIG 250 leaves porous welds on aluminum with 0.035-inch mig wire at 20 CFH argon, Any solution?

          Check for gas leaks on your Vevor MIG 250, use 25 CFH argon, fixes porosity.

            Clean aluminum with alchohol before welding, dirty metal causes porosity, use fresh mig wire.
