94378368 - Arcair K4000 Replacement Head and Screw Assembly

Heavy-Duty Replacement Head for K4000 Torches

Keep your air carbon-arc gouging operations running smoothly with the Arcair 94-378-368 Replacement Head and Screw. Designed for the widely used K4000 and K-3 Extreme manual gouging torches, this assembly is the front-line component that holds your gouging electrode in place. Given the extreme heat and physical wear associated with gouging processes, the torch head is a consumable component that requires periodic replacement to maintain safety and efficiency. This authentic Arcair part restores your torch to factory specifications.

Maximize Torch Efficiency

A worn torch head can lead to a variety of issues, including arcing between the electrode and the head, overheating, and poor air control. These problems not only reduce the quality of the gouge but can also damage the torch body itself. By replacing the head with the 94-378-368 assembly, you ensure a tight, secure grip on the carbon electrode and a consistent path for the compressed air. This results in cleaner grooves, faster metal removal rates, and less operator fatigue caused by fighting with inconsistent equipment.

Rugged Construction for Industrial Use

Arcair is the leader in air carbon-arc gouging technology, and their replacement parts reflect that expertise. The 94-378-368 head is constructed from robust materials capable of enduring high amperage loads and thermal cycling. It is also compatible with the Radnor Pro4000 series, making it a versatile part for shops with mixed equipment. The included screw ensures a solid mechanical connection, preventing the head from loosening during operation.

Maintenance Made Easy

Regular inspection of your gouging torch is vital for safety. If you notice pitting, thread damage, or deformation on the head, it is time to swap it out. This replacement kit provides everything needed for the head swap, allowing you to get back to work quickly. It is an essential spare part for any toolkit in heavy fabrication, maintenance, and repair operations.
