Just a follow up - new consumables were all I needed and it now cuts like it should.

I have alot of new consumables, they didn't help the problem..

Mine quit last year with the same symptoms. I called the factory and they said it is not supported any more. I have comfirmed the trigger switch is ok and all other functions appear to work ok... The rep "suggested" it is probably the pressure switch located at the incoming air source just under the top panel... If that part cannot be crossed over to another manufacturer then I will jumper it in the closed position..

My symptom is just like all the others complaint... it will spark/cut for a second or less...

I will report back on if I was successful

check your air pressure it might be to high. and it is blowing the arc out.
Set to mark on gauge with air flowing. 65 to 70 psi i think.
Second make sure you work lead is not broken inside the insulation and the clamp must make good contact. Pilot arc timer may turn off the arc.

Thanks for the tips....

I did try different pressures..

I was able to jumper across the pressure switch thinking was was preventing tha arc to sustain.. No Joy..

I did use my ohm meter to confirm the lead wire and the ground wire were ok...

You comment about the "pilot arc timer" seems to be the culprit as that is the exact symptom.. It is will strike an arc for a slight second and then go out, I can keep the switch held down and drag the gun across the test piece of metal and it will intermittantly try to refire but it goes out again instantly....


Too bad the factory quit supporting it as it worked PREFECTLY till the failure and I am guessing the "pilot arc timer" in embedded in the PCB and is made out of unobtanium...

I have a box full of consumables that are now going to the dump with the unit... What a waste...


Thanks again for the feedback...

Thanks again for all you guys feedback... My main beef is the fact the factory will not support the unit.. it is not that old either... It might be something simple I overlooked or a dead PCB.. I am in Wyoming so the freight will get pricey but if anyone wants it for parts, email me.
