Project #2 (210 EXT Contest) by DVA: TIG Water Cooler

[Mike J]

Any idea at that pressure and the hose sizes how my gpm you are making? I was reading somewhere about the pump has to have a good pressure and flow capacity to make sure enough water moves through the system, it looks like you have it. If you are running 30 psi, and linear loading, its about .9 gpm. Hard to compare to the EL unit, the gpm is not stated.

I guess the heat capacity is limited by the bucket, since there is no radiator, correct?

Very nice job!

Cheers,

Mike

I did not measure the flow rate but can do that.

As for heat capacity with a a radiator would help but there is a lot of heat capacity in a gallon of water. I have about 3.5 gallons of water in the cooler and was welding for about 1 hr the other day at 200 amps with a few breaks and with no noticable change in water temp during the one hr. When I build my welding cart I am going to add a radiator to the cooler.
