I picked up two brass fittings one that attached to a hose fitting the other adapted to a 1/4" hose barb 50' of polyethylene tubing and two double ended 1/4" hose barbs to attach the hoses to the torch it works pretty good. I just run a light flow of water through the tubing and dump it out in the tree bed. The draw back is that its not so portable. I don't weld a lot at high amps so I am not sure how it would work with a lot more heat. I bought everything for less than $20.00. It keeps my torch cool for now until my Power Cool 300 comes in.
