Hi, I have had a cobel 200 amp ac/dc tig for a few years now and I have been very happy with it. Recently though it has started playing up.
It will arc up using the hf start and maintain an arc but only at really low amps (not enough to create a pool in 1.6 mild steel). If I press the pedal or adjust the machine it makes no difference it still stays at the low amps.
I have had the cover off and there doesn't appear to be anything obvious. The only thing I have done differently is use it on ac for the first time a couple of months ago but it has worked since then?
Any information or ideas on what might be the issue would really be appreciated! Thanks
