94476068 - Arcair K4000 Trigger Spring Pin Replacement

Restore Your K4000 Torch with the Arcair Trigger Spring Pin

When you are deep in a gouging job, removing welds or preparing joints, the last thing you need is a torch malfunction. The Arcair 94-476-068 Trigger Spring Pin is the exact replacement part you need to fix a loose or non-functioning trigger on your K4000 or K3000 gouging torch. This pin is the anchor for the trigger spring, the component that gives you that snappy, responsive feel when you press the air valve lever. If this pin shears, bends, or goes missing during a rebuild, your air control is gone, and so is your ability to blow away molten metal effectively.

Designed for the harsh reality of the welding shop, this pin is built tough. It fits perfectly into the torch body, securing the spring so that the air valve seats correctly every time you release the handle. We know that air carbon arc gouging is a brutal process—high heat, sparks, and rough handling are part of the game. That is why using genuine Arcair parts is non-negotiable. This pin restores your torch to factory specs, ensuring that the airflow is there when you need it and shuts off completely when you don't, preventing air leaks that waste compressor power and create noise.

Installation is straightforward for any welder familiar with their tools. If you are rebuilding your K4000 Angle-Arc torch, this pin slides into the designated housing to lock the spring mechanism in place. It is compatible with a wide range of Arcair torches, including the heavy-duty K5000 and the Sea-Torch used in underwater applications. Don't let a ten-cent problem cause a thousand-dollar delay. Keeping a few of these pins in your toolbox or parts bin means you can fix a trigger issue in minutes and get back to gouging.

Your equipment is an extension of your skill. A sloppy trigger or a leaking air valve compromises your control over the gouge profile. By replacing worn-out internal components like the 94-476-068 pin, you maintain the precision and power of your Arcair torch. Whether you are working on heavy equipment repair, structural steel, or pressure vessel fabrication, trust in genuine Arcair replacement parts to keep your arc lit and the air flowing.
