94378366 - Arcair K3000/K5000 Extreme Replacement Head Assembly

Get Your Gouging Torch Back in the Fight

When you are deep in a gouging job, cutting through welds or washing away cracks, your equipment takes a beating. The head of your gouging torch takes the brunt of the heat and spatter. If you are running an Arcair K3000 or K5000 Extreme torch, the 94-378-366 Head Assembly is the part you need when your old head finally gives up the ghost. Don't struggle with a torch that overheats, leaks air, or won't hold the rod tight—swap it out and get back to work.

This isn't just a piece of metal; it's the heart of your gouging setup. It channels the massive amperage needed to melt steel and directs the jet of air that blasts it away. A worn-out head leads to sloppy gouges, frustrated operators, and wasted time. This genuine Arcair replacement is built tough to handle the extreme environments of metal fabrication and heavy equipment repair. It fits perfectly, installs easily, and restores the 'like-new' feel to your torch.

Why stick with genuine Arcair parts? Because in gouging, performance is everything. Cheap knock-offs often have poor conductivity, which means your torch gets hot in your hand instead of putting that heat into the work. They also often have misaligned air holes, which leads to messy cuts and slag that doesn't clear properly. The 94-378-366 is engineered to keep the air stream focused and powerful, making your job cleaner and faster.

Whether you are using the K3000 for general repair or the K5000 for heavy foundry work, this head assembly covers you. It is designed to grip the electrode securely, ensuring a stable arc and reducing the chance of rod breakage. Keep a spare in your toolbox or supply locker so you never have to shut down a job waiting for parts. With the Arcair Extreme Head Assembly, you are investing in reliability, safety, and the professional performance that defines your trade.
