The minimum on the machine is 20% balance, so I'll try just a hair above that and see what happens. At first I was attempting to sleeve weld a peice of 1.25x.125" into 1.5x.065 tube. Foot pedal wasn't doing it and I think it's because there wasn't enough heat. After setting the panel to 130 amps and using the torch switch it would make a puddle but it would require constant movement and massive filler feeding to make it somewhat stable. This was all with green tungsten.
With any other color there just isn't a shiny puddle that forms. My test piece was a 1.5"x .065 tube. Normally I use the pedal, but anywhere between a little pedal with preheat to full pedal with cold aluminum results in dirty welds that melt away before a puddle forms. I never pictured going almost full EN on the settings so that could be it. I attached a pic of my test piece. This is a combination of red, gold, and black.
I will try going way heavy on the EN setting and see how it goes this weekend. Thanks.
