94378007 - Arcair H-3 Replacement Head for K3000 Torch

Technical Overview of the Arcair 94-378-007 Head Assembly

The Arcair 94-378-007 is a precision-engineered Head Assembly (Model H-3) designed specifically for the Arcair K3000 Angle-Arc gouging torch (part number 01-062-000). In the demanding field of air carbon-arc gouging, the torch head serves as the critical interface between the power source, the compressed air supply, and the carbon electrode. Over time, the extreme heat and mechanical stress inherent in the gouging process can degrade the head assembly, leading to poor conductivity, air leaks, or electrode misalignment. This genuine Arcair replacement component restores the torch to its original factory specifications, ensuring optimal performance and safety.

Manufactured in Mexico to Arcair's stringent quality standards, the H-3 Head Assembly features robust construction capable of withstanding the high amperages typically associated with the K3000 torch. The assembly includes the necessary internal components to securely grip the carbon electrode and effectively channel the air stream required to blow away molten metal. Proper maintenance of the head assembly is vital for preventing overheating of the torch handle and cable, thereby extending the overall service life of the equipment.

Industrial MRO professionals recognize that using OEM parts like the 94-378-007 is essential for maintaining the integrity of the gouging system. Unlike aftermarket alternatives, this head assembly guarantees a perfect fit with the K3000 body, eliminating the need for modifications during installation. Its dimensions (0.6 x 3.4 x 5.5 inches) are calibrated for the specific ergonomics of the Angle-Arc design. By replacing a worn or damaged head with this authentic Arcair unit, operators can ensure consistent arc stability and efficient metal removal rates, maintaining the productivity of their metal fabrication or repair operations.
