Its definitely different. Trying to make aluminum beads with just up/down slope really helped me learn how to control the heat with just speed and the filler rod. Now I'm trying to get a custom to the pedal. Its only the second time I have had used a Tig with a pedal. I pretty much learned with scratch start. The HF start is also something I now wont be able to live with out. I love it too much!

As for the cooler, I plan on using a heater core I had laying around to keep things cool. Im going to couple a fan to the motor shaft instead of using a separate electric fan to keep things simple. here is the link to the pump im using. You cant beat 30 dollars shipped for a new Procon pump!

The only thing I need is a relief valve because this pump will do 170 psi! It will blow out my torch!
