My newest Portable is a Thermal Arc Predator Pro 270
I love the three phase welder, EXCEPT:
With just over 800 hours it now needs a third circuit board as the thing will spike to max amp and sometimes stay there, no matter where the dial is. Stop welding and sometimes it will be fine , other times not.
This is getting too pricey at $800.00 in parts to fix again.
Is there a cure for this issue or just give up and move on to another welder?
I am now looking at a Miller 302 (3 phase) to replace it if all else fails.
