two MIGs running parallel?

admin

I've been plugging away with my Miller 120V MIG for years and have had much success. Of course, every one wants more power. Had a couple of used TIG deals slip away and now I don't have the $ to buy a new machine. I wondered if it is at all possible for me to take my two, closely matched 120V MIG machines and run them in parallel? Just like stacking two batteries will double the available amperage(?). Google search found threads on tandem, robotic, MIG welders, but nothing as nuts as what I'm proposing.I'm hoping to slop some bead to fill in combustion chambers for modifying aluminum Corvair heads.

Reply:I know you can parallel CC power supplies, but no idea about CV.Real world weldin.  When I grow up I want to be a tig weldor.
Reply:Unless they regulate together, you don't gain much on a parallel.
Reply:Usually the only time CV power sources are parrelled is in high amp sub arc applications, and the machines are the exact same.Disclaimer; "I am just an a$$hole welder, don't take it personally ."
Reply:still would not matter..IMHOYour not fixing aluminum heads with a mig and thats that.. ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
