4.5 years on and after winter it wouldn't tig weld, only ignite the arc but then not go to full current.
Opend it today and thanks to my vast knowledge and decades of experience, thorough research and perseverance I fixed it
To be honest, I have no clue but after some wiggling circuit board connectors it just worked again, must have been slight corrosion due to my moist shed.
I did measure the resistance of the weld current pot.
It has three wires connected to it.
Central one to the right go's from 2k at 0A to 11k at 130A and then to 0k at full power.
No clue how or why but it works
Edit; and then the battery of my welding mask is depleted, just managed to pick one up before shops closed.
