Lot's of smoke, welding aluminum

[fishbum]

I have that same spool gun. Sucking air around
top of tube. I have to run more wire feed than I think I should.

Can you put up a couple of pictures of your welds?

If that wasn't working you wold not have much power if any.... I still think you have your leads on wrong.

is it possible that the 230v part of the machine is defective? looking for someone in los angeles, ca that can do repair.

yes I am on 100% argon, i did not change my wire positions so i should be on positive lugs. i am testing on 1/8" and 1/4" there is no penetration. i just tried it on 110V it works better, i get penetration but there is still lot's of white smoke. thanks

Also leave the gun on the positive lug.

How thick is the aluminum? Old stuff is hard to prep esp if there is a seam that has crap in it...Bob

i have a miller 211using spool mate 100 series. i am not a professional welder but did aluminum welding before on a number of projects with the same equipment. i am now retrofitting an aluminum trailer and i cannot get my equipment to work properly. i get lots of smoke and the aluminum wire is not penetrating the aluminum. i clean with acetone and steel brush. i have tried different settings, wire feed and voltage nothing seems to work. i am connected to 220 voltage. thx

100% ARGON.... Not C25,,,???
