Transtig 161 won't work on AC
- Thread starter Baz1086

It's probably a job for ESAB service, though first, have a look inside and clear any dust off the internals. Murex recommend periodically cleaning the internals every 12 months using clean dry compressed air at reduced pressure. Have a close look at the com board (commutator board) for signs of damage, and loose connections.
The rights to the Murex brand were sold to ESAB, so ESAB would be the way to go for repairs.

Ok I definitely do not have a sound knowledge of electronics, one thing I have noticed is I did take a look inside the welder at the panel and at the AC DC change over switchLikely possibilities are: faulty AC/DC front panel switch; commutator board fault; a fault with the board that is sending control signals to the commutator board. A sound knowledge of electronics will be required to fix this.
And since removing the control knobs from the front, the two position AC DC switch now turns like a rotary switch!
I'm not sure what has happened to it? I only noticed when I put it back together
I was wondering if it is the switch at fault, or if there was some sort of clip/restrictor that has dropped out?
Either way that ac dc switch that was two positions is now a rotary switch
???

After looking at the wiring diagram I can see there are 4 diodes built into the AC DC change over switchLikely possibilities are: faulty AC/DC front panel switch; commutator board fault; a fault with the board that is sending control signals to the commutator board. A sound knowledge of electronics will be required to fix this.
I'm wondering if one of the diodes has gone in the switch?
If this were the case then would the HF still work and the gas solenoid on the AC setting ?
Cheers
As a follow up to this I took my welder to a welding repair shop in Kent that worked on boc murex stuff and they could not tell me what was wrong they basically said parts aren't available and wasn't worth repairing
But they did have brand new jassicks for sale!!
I sent it up to technical arc in York and they repaired it
They told me what was wrong without seeing it!
It was the AC chopper had gone down
They fitted a new one and sent the machine back for £188 all in including postage
I'm very happy with it
Cheers
