Wow,

That's pretty thin stuff. I would say your best bet would be a micro-tig unit. These type of units usually get down to .1 amp and some even below that. We do not currently offer anything in the micro area and the lowest amperage our units go to is 1 amp.

Sorry, wish we could help.

Good luck

Andy

You should look into a VPPA unit (Varible Polarity Plasma Arc) I built one for thin and thick aluminum alike. Depending on your weldment joint, keyhole plasma and plasma stabilized tig should be valid options.

krishnan, send me an email and i will send you information on some specialty variable polarity tig and plasma equipment.
