Lack of understanding and in need of advice. I work with a Transmig 3ph unit with a stand alone wire feed unit. The power unit has readout for volts and amps. I have had problems with welding performance wandering off setting, even during welds. Watching a colleague, and the machine, the voltage was fluctuating along with the amps. I was under the impression from my text books that this design of unit held the voltage fairly constant, and the current was altered with the wire feed speed.
Any advice on what may be causing this?. Our repairer is going to try another feed unit control board next week, but seems equally baffled.
