Hi, long time lurker on here.
I took a punt on ebay at an iffy looking Kemppi Master tig AC/DC pulse and ended up winning it.
It's grubby and appears the inverter and HF side of things are all ok but it does have one fault: The knob on the font that adjusts the amps and other functions after a button press like pre- and post- ramps doesn't do anything.
On switch on it's stuck on 50 Amps which I assume is the default, the dial is a rotary encoder rather than a pot. I pulled the panel off and it looks like someone has replaced the encoder in the past, I don't know if this was a failed repair with the wrong part or what.
I'm still checking the obvious things like connectors and continuity, and I have borrowed a 2 channel scope to see what the rotary encoder is doing.
But does anyone have a Kemppi panel they could take a photo of the back of in the area of the Amps dial so I can see if the encoder is the same as the one on mine.
If all else fails does can anyone recommend someone in the Essex area that could take a look at it that wont just go straight for the new panel option, i.e. might be able to chase the fault down and replace the component on the board.
Thanks for listening.
