Hey Zap! Eat your heart out man!! No more burnt fingers! I ran 220amps on some bronze tonight and the only heat I felt was radiating on the scrap piece! Only downside, the cooler is loud full time! Now I see why this old tony removed the fan for some computer fans. If it bothers me enough, I might consider the same thing. After reworking the shitty HF mig cart, it takes up little space this way. Series 20 CK torch. I like the rigid head, but need some shorty back caps.
