ユニオン電機 List of Products and Services

Are you having trouble with a foot-operated capacitor-type welding machine like the Highmax 500? Our company repairs welding machines with faulty capacitors and other components by replacing them with new welding machine power supplies. We can propose single-phase AC, inverter, capacitor, and transistor power supplies tailored to your work. The "foot-operated head" from Highmax can be reused, allowing you to continue using your existing electrodes and jigs, which makes it more affordable. The photo shows the removal of existing capacitors and transformers, with our single-phase AC power supply UAR-26 and transformer UT-7W5D installed. *Maximum short-circuit current: approximately 4KA (depends on the transformer used). *Since there is a possibility that PCB may be included, please provide the manufacturing year, model number, etc., before we take it in. If it is determined that PCB is included, we may refuse the modification.
