Testing Procedures for Arc Welding Transformer Machines: Effective Methods and Troubleshooting
To test a resistance welding transformer, first disconnect the power. Use an ohmmeter to check for shorts between the weld studs. Measure the voltage using a mega-ohm meter in DC when not welding. A zero-ohm reading suggests a shorted diode. Follow these steps to ensure proper electrical performance, including checking current shunt and capacitors. Another … Read more
