First aluminum welds

[Matt@RFR]

My thinking was that with 3/32 filler, you shouldn't be having any problems getting the puddle to fill up, especially with how close together you're adding filler. And your max amperage (140) is alittle hot, but not too bad.

Helium mixes burn hotter at the same amperage as pure argon.



I'm willing to bet, assuming pure argon, that the main thing you need to work on is arc length. You should be able to see the reflection of the tungsten in the puddle when your arc length is short enough.
