So I have a miller 200dx. Trying to tig soda cans together. I can get a bead going for a inch or so. What size tungsten do you recommend? Im using .020 and 1/16 filler. at about 15 amps
For welding aluminum cans, The biggest help is poking a hole in one of the cans to keep pressure from building up. Pressure builds up quickly and then blows your shielding gas away and wont let the puddle wet in.
A trick for tig welding aluminum cans , though some might call it cheating, is to run a bead around the ridge first. That adds a little thickness and also pre-cleans the area. I would set the a/c balance to 65 and the Frequency to 120 along with the other tips listed.
