Hello all,
I want to relate a problem I had with my PowerCool W300, in hopes that it will save someone else a big headache.
I was welding the other day for about 10 minutes at 170 amps AC with my WP20 torch, when I happened to look at the sleeve containing my cables and noticed that the power cable melted through the water jacket. I suspected that the pump was not doing its job, even though the water reservoir would get warm when welding (suggesting there was water flow through the torch).
I emailed tech support yesterday (with my phone # included) at 11:45 central standard time to ask for help as not to void my warranty. No response as of this morning. I decided to take matters into my own hands, and found the flow rate of water out was about 1 drop/ second. Not much flow happening there. I investigated further to find that there is a silicon rubber grommet in the reduction connector to the water out, that was restricting flow. I trimmed the inside diameter of this grommet with an exacto knife and reassembled. Water now gushed out of the connection.
What a shame I had to burn up a perfectly good WP20 torch to find I had a problem with restricted flow from the water cooler.
By the way, still no response from tech support.
The PowerCool W300, PT 250EX, WP20 torch, and cart were all purchased in late December 2011.
