I think I was just measuring the voltage at the wrong wires that time, there is 230 V AC coming to the transformer, and I can get an arc if I push the button in the center of contactor, but no wire feed.
There was some kind of modification done to this mig by previous owner, maybe that is...
Thank you for this clear explanation, now I can clearly understand how it works.
So I have measured the transformer primary and secondary voltages today, at the maximum setting the primary voltage is 32,6 V, and the secondary voltage is 4,6 V at the thick wires, which go to the rectifier. Why...
There is 0 V across the wires of contactor coil when I press the trigger. Yes, there is a small relay on the PCB of wire speed control, the same relay as in the photo, which was posted by gaz1, I wonder which contacts of the relay I should check to measure if there is 230V or not.
I will try to...
Hello,
I have Cebora pocket turbo 130 mig welder, and it suddenly stopped working. Few days ago it worked fine, and today, when I tried to weld, there was no wire feed and no arc. I can hear the transformator working, the fan is spinning, power control buttons are working, I can control the...
