All of our new torches are air or water cooler compatible. And the buttons are built in (there is a picture on our website under details). Only one model is not. Which one are you looking at?
Both are air/water compatible. I will check the rating, but I thought it was 300amp +. Mark might know it off the top of his head. Otherwise I will look it up. Surprised it is not on the page yet.
On your Welders there are two units that I wanted to know what TIG torch handles they come with: the PowerTig250EX and the PowerMaster226
Thanks in advance,
