9ST11236-1 - Replacement Electrode for 9SS18310 Spark Gap Assembly

Restore Your Welder's Instant Start

Is your TIG welder struggling to start an arc? Do you hear the high-frequency buzzing but see no spark, or is the start erratic and unreliable? The culprit is often a worn-out spark gap assembly inside your machine. The Electrode for 9SS18310 Spark Gap Assembly (9ST11236-1) is the direct replacement part you need to get your machine firing like new again.

The spark gap is the heart of your welder's High-Frequency (HF) start system. Every time you step on the pedal, high-voltage electricity jumps across these electrodes to create the initial path for your welding current. Over thousands of starts, the tips of these electrodes burn away and become pitted. When they get too worn, the voltage can't jump the gap effectively, leaving you frustrated with a torch that won't light. Replacing these electrodes is a standard maintenance procedure that can save you from expensive repair bills or the false assumption that your machine's board is fried.

Note: The 9SS18310 assembly generally uses two of these electrodes facing each other. While this part is sold individually, we recommend checking both sides. If you are opening up the machine to service the spark gap, it is often best to replace both to ensure a crisp, clean, and consistent gap setting. Always consult your welder's service manual for the correct gap spacing (usually around 0.008" to 0.012") to ensure optimal performance.

Why Replace Your Spark Gap Electrodes?

• Instant Arc Starts: Eliminate the frustration of false starts and sputtering.
• Protect Your Machine: A properly gapped HF unit puts less stress on the machine's internal capacitors and transformers.
• Simple Fix: Often the solution to "no HF" problems, avoiding costly service center visits.
