So b-o-b, do you have the cooler hooked up to the htp221. I've been looking/thinking about the artic chill for some time now. I will be going for the dv setup when I pull the trigger. I spent about 7k on HTP equipment last year and had to let the debt card cool off a bit.
Should be ready to pull that trigger before too long.
I used my 221 air cooled torch to weld some parts for a construction company that were all 1/4 material. I had to add helium to get the performance needed. I also ruined a torch cable, but that was all my fault. How thick of material can you weld with the small water cooled torch?
Glad to hear the good things about the cooler.
