94433190 - Arcair Extension Insulator and Plenum for 05-124-001 Torch Head

Keep Your Gouging Torch Running Smoothly

When you are in the middle of a heavy gouging job, the last thing you need is a torch failure. The Arcair 94-433-190 Extension Insulator (also known as a Plenum) is the exact part you need to revive a tired or damaged torch head. Designed specifically for the 05-124-001 Torch Head assembly, this part is the heart of your torch's safety and performance. Over time, the intense heat and flying sparks of the gouging process can degrade the internal insulators of your torch. If you notice air leaks, inconsistent airflow, or signs of thermal damage near the head, it is likely time to swap out this component.

This isn't just a piece of plastic; it's a specialized heat shield and air director. In carbon arc gouging, the "blast" of air is what actually removes the metal after the arc melts it. This plenum helps shape that air stream, ensuring it hits the puddle exactly where it needs to. If this part is cracked or worn, your air pressure might drop at the tip, leaving you with messy grooves and slag that is hard to clean. Furthermore, it acts as a vital safety barrier, keeping the electrical current contained within the conductive parts of the torch and away from the handle or outer shell.

Using genuine Arcair parts means you don't have to fight with the fit. It slides right into place on the 05-124-001 head, sealing up tight so you can get back to work immediately. Whether you are working in a foundry, a shipyard, or a fab shop, keeping your equipment in top shape is part of the trade. Don't risk your weld quality or your safety with makeshift fixes; install the correct Arcair 94-433-190 insulator and keep the sparks flying in the right direction.
