94123017 - Arcair Tri-Arc Torch Valve Button Repair Kit

Fix Your Tri-Arc Torch Air Valve

If you are running a Tri-Arc foundry torch and experiencing issues with your air control, the Arcair 94-123-017 Valve Button Kit is the solution you need. The air valve is one of the most frequently used moving parts on a gouging torch. Every time you strike an arc, you are engaging the air to blow away molten metal. Over thousands of cycles, the button mechanism can become gritty, sticky, or loose. A sticking button is not just annoying; it can be dangerous if the air doesn't shut off when needed, or frustrating if it won't engage fully, leading to poor metal removal and slag entrapment.

This kit is designed specifically for the heavy-duty Tri-Arc model, which differs from the standard K4000 angle-arc torches. The Tri-Arc is built for the extreme heat and abuse of the foundry floor, and its internal components are robust. However, even the toughest tools need maintenance. This kit allows you to replace the external button and the immediate actuation mechanism, restoring that crisp, responsive feel to the air valve. When the air flows correctly, you get cleaner grooves, better visibility, and less cleanup time.

Installation is straightforward for anyone familiar with torch maintenance. Simply disassemble the valve housing area, remove the old, worn button assembly, clean out any accumulated carbon or dust, and install the new 94-123-017 kit. Using genuine Arcair parts ensures that the O-rings seal tight against the air pressure (often 80-100 PSI) and that the button spring tension is correct. Don't let a $20 part compromise the performance of your heavy-duty gouging operations.

Symptoms of a Bad Valve Button

• Sticking: The button does not return to the off position immediately after release.
• Hard to Press: Excessive force is required to engage the air flow.
• Air Leaks: You hear hissing around the button area even when the valve is supposed to be closed or fully open.
• Intermittent Flow: Air cuts out during the gouging pass.
