I wasn't talking about the torch tip but the whole torch/hose set-up. They look to have the same connections at the machine.



Also, on the replacement torch, I inspected it and on the 'ball-point' pins, one looked like it arced because the tip looked a little melted. It is also doing the same thing the other torch did. There is a 1-2 second delay before the pilot arc starts and some times the arc stops after 1-2 seconds. Not enough time for any temp build up to cause shut-down. I don't think the trouble is in the torch.

All air hoses are now tight without any leak.

You'll need to talk directly to mike.

The delay is normal. But I am wondering if you have a pinched line inside the unit that is preventing full flow once the torch line is inflated to full psi, and blows the piston back it drops as the pressure is relieved, then the piston slams back shut.

But no the torch start technology is entirely different and they will not interchange. You don't have high frequency on this unit and the other torches are high frequency. Technically, if you could adapt it, a Miller, hypertherm, Radnor, or even a thermadyne torch with blow back start would work but not any other type.

It is possible that you have a weak solenoid.

I did mention when there was no arc at all, that I could hear the solenoid activating and shutting down when the hose filled and collapsed with air. Not sure what that meant but got it kinda working before the replacement


Today I was cutting tack welds from a SS swim platform on a boat that was in an accident. The SS parts are expensive so I wanted to re-use what I could. most of my cuts were only 1 sec long so there was no problem.



I will soon be starting on a SS exhaust system and the 3/8" SS mounting plate was a concern If there was no continuous arc cutting out the exhaust ports.
