Got my cooler made

Nice work, too bad they discontinued your pump. Anybody know what the flow rate of the average torch cooler is?

Answering my own question here: Miller seems to be around 60 GPH with a max torch output of 200A (Coolmate 1), the Coolmate 3 is ~65 GPH @ 500A. So the pump in these units are not that big. I found this one on eBAY:

Overkill @ $55 bucks

Add a cheap heater core, fan and a tank and you're almost there....

Othe places sell that pump although for a little more $$

When I ordered it the site said while supplies last and that was 2 weeks ago

Tonight I finally got the new power cable for my WP20 and was able to get some real testing for my cooler as I'm pretty sure the water passages in it are smaller than the Everlast torch.

First was the flow tests. I don't have a flow meter so all I could do was watch the return line and monitor the flow. It didn't appear to change at all for the flow test with the Everlast torch. Then, to really test the pumps performance, I hung the torch to ceiling in my garage (about 7 feet up) to test if it had enough pressure to push the coolant that high. Flow looked exactly the same as the first 2 tests.

Next it was time to test the cooling ability. For this I took a piece of 1/8" thick, 4"x2" steel and proceeded to lay down bead after bead only stopping long enough to reposition for the next pass. I had the amps set at 160 was was running pretty much full pedal the entire time.

The temp prose from 53*'s to 72*'s (Don't tell the wife I used her oven temp probe )

I have to admit I'm little surprised it rose that much but also I have to remember that this (for me) was an extreme test and that I'll probably never be doing any welding like that. At least nothing I can foresee.

Over all I'm pleased with it's abilities and I'm fairly confident it will be more than adequate for my needs. I am just a hobbyist after all and my needs aren't that great.

At least now I can weld with out my torch hand starting to smoke and FWIW, I think my welds are getting better.





I really need to get the hang of welding round pipe before I have to weld on my daughters dragsters.
