Hi,
So I have this old Tig/MMA welder ESAB tigma 150
At least that is what I think the name of it is, because there is no name plate or anything on it. But from searching around on Google, the tigma 150 looks very much the same as my welder.
Anyway the welder is not working properly anymore.
The Funktion of the button on the handle is no longer working.
The gas flow and welding current is on from when i turn on the welder, instead of being triggered by the button.
So it can weld, but the liftarc is no longer working, I have scratch start the welding which is not ideal to say the least
I have measured/tested the button and it is ok.
I also opened up the welder. There is a relay inside I can't figure out the function of it, but I took it out and testet it, it also works fine.
The two circuit boards also visual looks ok, quite a bit dirty but other than that..
The fan was blocked, but is running now.
Maybe something had been to hot because the fan wasn't spinning
The magnetic valve for the gas flow is in good condition and is working. It is open because there is voltage going to it from the pcb.
I am out of ideas and abilities really..
Maybe someone here has some ideas to what could be the problem here ?
Best regards
Peter
