I have just replaced the rectifier bridge in my Murex tradesmig 130 with a 170 amp version from TecArc. I am now getting six different DC voltages on the DC side of the rectifier - a result!
I am also getting six different voltages between tip (after removing gas shroud) and earth clamp when I pull the trigger. However, the voltage drops to zero when I let go of the trigger.
Before the old rectifier completely gave up - to the point where I was getting six different AC voltages going into the rectifier but zero DC coming out - I used to get six somewhat lower DC voltages between the tip and earth clam, but the reading was not dependent on the trigger.
I do not know whether I am supposed to continue to get a reading when I let go of the trigger.
It may be that the voltage between the tip and earth clamp should stay constant until the capacitors discharge, in which case I may have a problem with the capacitors. Alternatively, it may be that the voltage should drop when the trigger is released, in which case it may mean that the old rectifier was on its way out for a while before it completely gave up.
If someone could please point me in the right direction, I would be grateful.
Thanks
Jonathan
