My little Hobart 135 has been acting up It isn't getting a good weld and air pockets in the weld. I put on a new gauge on the Argon C02 tank but still pin holes.
Any ideas on what I need to do?
Check polarity. Fan running and blowing across your work? Whats gas set at? Porous welds can form due to various reasons. Dirty metal, incorrect gas flow rate.
