My sweet 250EX has gone on siesta...

I was welding with my 250EX an lost high freq. so I uncovered it, adjusted points. Great! Back to welding beautifully! After about an hour, it stopped welding. Still have high frequency but no current. I check all connections. Took cover off and visually inspected it and blew it off again. Still no current. Can anyone lead me in right direction? Thanks.

Sometimes we just get lucky... just before my 250EX quit working, I ordered a 20 series 25? torch. It arrived and when I hooked it up, machine worked.

Nice,

So, you probably just smoked the previous torch/cable/hose then?

Was it gas-cooled, and now you're going to water-cooled?

I'd check your water lines for good circulation. Maybe there was some frozen lines.

Does that 250EX have a direct plug for the water cooler, so that when the welder turns on, so does the cooler?

I previously had the big water-cooled torch. Yes, machine has direct plug for water cooler. I think you?re right. At some point I smoked the original torch.
