Afternoon All,
I've got a 2010 vintage 160A AC/DC TIG set that on Sunday that while tacking at about 40A, jumped to 236A. Mega arc, pothole in my workpiece and still a bit of a bright spot when I close my eyes so I'm fairly certain it achieved the stated 236A.
It's now stuck on 236A and the pots and switches on the front panel have no effect in any configuration or setting. The gas solenoid stuck open on failure and only closes with a power cycle. After I'd disconnected the bottle, I found that the gas solenoid will click as the current pot is turned below about 30A but not sure if this is opening or closing.
I've already been on the phone to RTech to book a courier to collect for inspection but while I'm sat here musing (they're quoting 10-14 days leadtime on repairs at the minute), wondered if anyone else had seen this issue and what the resolution was. I see cnc_freak had a similar issue in 2015 but there's no follow up on the resolution. Being in Greece, I don't know if they'd have sent it back to RTech.
I've had the covers off to investigate the boards, but can't identify any skid marks or damaged components. Shame really as it's all through hole so would have been easy enough to swap components out. I'm hoping it's economically viable to fix, if not, I'd best start thinking of projects needing 236A...
I'll keep you posted.
Cheers,
Tom
