OVERVIEW

Restore Your Welder with the ESAB 359C304 Transformer

When your industrial welding equipment goes down, every minute of downtime affects productivity. The ESAB 359C304 Transformer is a critical replacement component designed to step down 115V input power to a safer, usable 42V for control circuits. As a genuine OEM part, it guarantees the precise electrical characteristics required by your ESAB machinery, ensuring that repairs are effective and long-lasting.

Electrical components in welding environments face harsh conditions, including vibration, heat, and dust. This transformer is built to meet ESAB's rigorous manufacturing standards, offering robust insulation and reliable performance. Whether you are troubleshooting a control board failure or replacing a burnt-out unit, installing the correct transformer is essential for the safety of the operator and the longevity of the machine.

At Josef Gas, we understand the importance of having the right parts on hand. This 115V-42V transformer is typically found in various ESAB power sources and wire feeders. By choosing the authentic 359C304 part, you avoid the risks associated with generic electrical components that may not handle the specific load requirements of heavy-duty welding operations.

FAQ

It steps down 115V input voltage to 42V output voltage to power internal control circuits.

Yes, this is a genuine OEM replacement part manufactured by ESAB.

Symptoms often include the machine powering on but having no display, no wire feed, or no arc initiation, often accompanied by a humming noise or burnt smell from the component.

It is designed specifically for ESAB equipment. While voltage specs might match, mounting and amperage ratings may differ, so we recommend using it only for specified ESAB models.

Yes, due to the high voltages involved (115V), installation should be performed by a qualified electrician or welding machine repair technician.

The secondary (output) voltage is 42V.

Typically, transformers are sold as the unit itself. You usually reuse the existing mounting screws or brackets from the machine.

Check the parts manual for your specific ESAB machine model or look for the part number 359C304 printed on the existing transformer.
