OVERVIEW

Precision Replacement Component for HF Units

The 9ST11236-1 Electrode is a specialized replacement component designed specifically for the 9SS18310 Spark Gap Assembly. In industrial welding power sources, particularly those utilizing High Frequency (HF) for non-contact arc initiation in TIG welding, the spark gap assembly is a critical subsystem. It generates the high-voltage pulses required to ionize the air gap between the torch and the workpiece, allowing the welding arc to establish without touching the tungsten to the metal.

Over time, the electrodes within the spark gap assembly erode due to the intense electrical discharge they facilitate. This erosion leads to a widened gap, resulting in inconsistent arc starting, misfires, or a complete failure of the HF start function. This replacement electrode is manufactured to precise tolerances to ensure it fits perfectly within the 9SS18310 assembly, allowing maintenance personnel to reset the gap to factory specifications (typically measured in thousandths of an inch).

This product is sold individually, though the 9SS18310 assembly typically requires two electrodes to form the gap. It is recommended to inspect both electrodes during maintenance and replace them as a set if significant wear or pitting is observed. Regular maintenance of the spark gap ensures the longevity of the welding machine's starting circuit and reduces downtime in production environments.

FAQ

It acts as the discharge point in a spark gap assembly, creating the high-frequency voltage needed to start a TIG or Plasma arc without touching the workpiece.

The assembly typically requires two electrodes to form the gap. This product is sold as a single unit, so you may need to order two if replacing both sides.

Symptoms include hard starting, erratic high frequency, or visible pitting and erosion on the electrode faces when inspected.

The gap setting varies by machine model, but is typically between 0.008 and 0.012 inches. Always consult your machine's service manual for the specific specification.

No, this electrode is specifically designed to fit the 9SS18310 Spark Gap Assembly found in specific welding power sources.

You can sometimes clean and re-gap them if the wear is minor, but if they are deeply pitted or worn down, replacement is necessary for reliable performance.

No, this SKU is for the electrode itself. You will typically reuse the existing mounting brackets or holders in the assembly.
