94800077 - Arcair 94-800-077 Replacement Spring for K4000 & Pro4000 Gouging Torches

Keep Your K4000 Gouging Torch Running Tight

There is nothing more frustrating when you are deep in a gouging job than a carbon rod that won't stay put. If your electrode is slipping, sliding, or twisting while you are trying to wash a weld, you aren't just losing time—you are risking your equipment. The culprit is often a tired, worn-out spring in your handle lever. The Arcair 94-800-077 Replacement Spring is the exact part you need to bring that snap back to your K4000, K-3, or Pro4000 torch.

When that spring gets weak, your torch jaws don't bite down on the copper-coated carbon hard enough. This causes arcing inside the head of the torch, which heats up the handle to unbearable temperatures and eventually melts your insulators. For the cost of a simple spring, you can save yourself from having to buy a whole new torch head or rebuild kit. This is a genuine Arcair part, meaning it is made of the right steel to hold its tension even when things get hot.

Installation is straightforward for anyone familiar with torch maintenance. You simply disassemble the lever mechanism, swap out the old, compressed spring for this fresh one, and reassemble. You will feel the difference immediately—the lever will have that firm resistance, and your carbons will lock in solid. Don't try to rig it with rubber bands or makeshift spacers; fix it right and get back to moving metal. Whether you are in a shipyard, a fab shop, or out on a rig, keeping a spare 94-800-077 in your toolbox is cheap insurance against downtime.
