I just opened up my new HH210 MVP w/ spool gun, hooked up to argon and some 220v to try the only aluminum I had laying around, AL electrical conduit (I have a shipment of the real stuff coming tomorrow).
The reason I ask is that the welds came out really crappy, no penetration or burn through and lots of spatter. I had the argon at about 20-25 using 4043 .30 and 5/70 on the machine.
PS, any tips on welding AL or good articles, older threads, etc... would be great!
