First Time to TIG Aluminum Problems

[gtty]

I have finally found some time to try out my PowerPro 164 on aluminum.

I first tried to practice on a couple of aluminum cans and it was blowing through the cans even at lowest amps. I used up to 20lpm argon thinking I wasn't doing something right.

I then got out some 1/8" aluminum and sanded it off and tried to create a pool of metal. All I could accomplish was to melt the 2% Thoriated tungsten up inside the cup and the arc would just barely create a pool of metal. I turned the machine up as well as the gas and as you can see (be kind), I just burned through the piece.

Can anyone look at the photos and see if there is a setting I have wrong. I watched the "Mr. Tig" video and I thought I copied his setting on the PP164 video.

Note: I pulled the tungsten out of the torch so you could see what happened to the end. It took almost no time for this to burn off up into the torch. All the toggle switches are in the upward position.

Thanks for the help.
