11 months ago I bought a used TIG 161 in preference to one of their MIG units with loads of liners, torches, a spool gun etc on the basis that I could replace my nasty gasless MIG with a better one for some cash one day but would never afford (justify) a TIG unit. So, day one and the MMA was dead. Collected and repaired by R-Tech without trauma. Thinking that my warranty is nearly over (only 1 year on s/h units) I thought I'd better check the TIG operation.
This is what happens:
2T, DC setting, no pulse, 10s post-flow, 80A base current. Click with the torch and, after a brief pulse which I would expect to be the arc being established, the displayed current drops to 10A and remains so, after I have released the trigger, until the post-flow gas stops. Only the slightest pimples appear on the workpiece. Same happens with the pedal.
Thoughts please so that I don't appear completely stupid when I ring R-Tech on Tuesday.
