ESAB 673578 High Frequency Spark Gap Point

Genuine ESAB 673578 Point Spark Gap for Welder Repair

Keep your welding equipment running smoothly with the ESAB Point Spark Gap (673578). This authentic replacement part is essential for the proper function of High Frequency (HF) start circuits found in many ESAB TIG welders and plasma cutting machines. The spark gap assembly is the heart of the HF system, generating the high-voltage spark necessary to jump the gap between the tungsten electrode and the metal workpiece. When these points wear down from repeated use, the gap widens or becomes irregular, leading to unreliable arc starts that can hamper productivity and weld quality.

Designed specifically for ESAB machinery, this spark gap point ensures that your welder maintains the correct voltage breakdown characteristics required for a stable pilot arc or HF start. Unlike generic aftermarket electrical components, this OEM part is manufactured to the exact dimensional and material standards set by ESAB engineers. This ensures not only a perfect physical fit inside the machine chassis but also consistent electrical performance. If your TIG welder is struggling to start an arc, or if you hear the HF buzzing but see no spark, inspecting and replacing the spark gap points is often the required fix.

Maintenance of the spark gap is a standard procedure for industrial welding equipment. Over thousands of start cycles, the surface of the point can degrade. Installing a fresh ESAB 673578 point allows you to reset the system to its optimal gap setting, ensuring a strong, reliable spark every time you press the torch trigger or foot pedal. This part is ideal for in-house maintenance teams, welding repair shops, and fabricators who service their own equipment. Don't let a small internal component stop your production line; keep your ESAB welder performing like new with genuine replacement parts.
