I purchased this machine used from a guy that was using it in his garage. He was just running the water from his sink faucet into the welder and letting the return run down the driveway. I initially used a flowjet pulse type pump for about 3 years attached to a water container out of a Falcon corporate jet. It finally gave up after multiple patch jobs. When I took it to the local flowjet retailer, it was a discontinued model. They were unable to supply me with a pump because I had no specifications. To replace that pump I used a GM fuel injection pump out of a Corvette. That worked for about a year and then it pitched also. I don't think those fuel pumps like pumping water (too heavy for them I think). Lately I've been running Kawasaki Vulcan fuel injection pumps, but their life span isn't the greatest but like all the other pumps I've been running, they are free. My question is: what are the specs for the water pump needed to keep this welder in operation? The price of the usual cooling system is more than I would like to spend. I don't use this welder that much, probably not more than 5~10 minutes at a time. I've been sniffing around the McMaster-Carr website but I don't know what kind of pump I need, hate to waste money on a pump that will blow up soon.
Thanks for your help.
