673578 - ESAB 673578 High Frequency Spark Gap Point

Restore Reliable Ignition with the ESAB Point Spark Gap

The ESAB Point Spark Gap (673578) is a vital internal component designed for the maintenance and repair of select ESAB welding power sources and plasma cutters. In TIG welding and plasma cutting, the ability to initiate an arc without physically touching the electrode to the workpiece is crucial for preventing contamination and ensuring a clean start. This non-contact starting method relies heavily on a High Frequency (HF) circuit, where the spark gap plays a central role. Over time, the points within the spark gap assembly can erode, oxidize, or become misaligned due to the intense electrical discharges they facilitate. When this happens, operators may experience erratic arc starting, weak sparks, or a complete failure to ignite the arc.

By replacing worn components with this genuine ESAB Point Spark Gap, you ensure that your equipment continues to operate at factory specifications. This part is precision-engineered to handle the high voltages required to ionize the air gap between the torch and the workpiece. It is manufactured from durable conductive materials that resist rapid pitting, although regular inspection and maintenance of the spark gap assembly are recommended for optimal performance. Whether you are troubleshooting an older Heliarc machine or a specific ESAB plasma unit, using authentic OEM parts is the best way to guarantee fitment and safety.

Professional welders and maintenance technicians understand that the reliability of a welding machine often comes down to the condition of its internal components. A failing spark gap can lead to downtime and frustration. Installing the ESAB 673578 restores the crisp, immediate arc start that ESAB equipment is known for. This component is sold individually, and depending on your specific machine's assembly, you may require a set to complete the repair. Always consult your machine's service manual for proper installation procedures and gap spacing specifications.
