I'm puzzled here. I've been welding on a project for a few days. During the holidays, I cleaned up the garage and now resuming the project. Using all identical settings as before, I can't get a proper weld down.
Material is 3 and 4 mm aluminium. Everything cleaned with SS wire brush and aceton (filler only aceton).
Welder settings I have tried:
- 90 - 150A
- 8 - 16 lpm 100% Argon
- -40 - +10%
- 100 - 135 Hz
- grey 1/8" tungsten, used, new, sharp, dull,...
- gas lens
- #5 and #6 gas cup
When welding at 90A, I can get a shiny weld puddle, but it's way too small to do anything with it. 120A is still tricky, but I could seem to get a weld bead for 2cm, I did have to move left right to get the fillet. 150A is pure crap, it melts, and I can keep pushing filler in, but there is no real weld bead, I have no idea were all the material is going.
When I was trying some settings (25x25x3 square tube):
Giving it a go on the part I need to weld (60x25x3 rectangular + 4mm plate), same settings as the corner fillet:
What's going wrong? I'm out of ideas..
Thanks for the help!
