UN1-125 type butt welding machine working principle, who knows, I encountered the problem is welding power, but can not work, who can give I I answer?
Now domestic welding machine number is quite confusing. First of all, would you like to tell me whether it's pneumatic or manual?. Separately, it is simply that the machine uses no compressed air as the source of air.Then, the problem you describe is relatively simple, and the welder doesn't work on power. What you mean by "electrify" means that the control box has electricity or other display power is on. Or is there a connection between the two electrodes, and there is no electricity through the work room? You can explain it in detail so that I can explain it to you.
Do you mean a magnet for an AC contactor? Coil replacement, first of all, you change the coil voltage, right?. You first use the multimeter to test the two coils of the coil, there is no voltage
Bad contact at the output stage
