94048120 - Arcair K-3000 Replacement Upper Arm Assembly

Genuine Arcair K-3000 Upper Arm Replacement

Maintain the integrity of your heavy-duty gouging equipment with the Arcair 94048120 Upper Arm, specifically engineered for the K-3000 manual gouging torch. The K-3000 is renowned for its ruggedness in metal removal applications, but even the toughest tools require maintenance. The upper arm is a moving component that endures significant stress every time the lever is depressed to insert or adjust a carbon electrode. If this arm becomes bent, cracked, or worn at the pivot, the clamping force on the electrode is compromised. This can result in arcing between the jaw and the electrode, causing damage to the torch head and reducing process efficiency.

This replacement part (Internal SKU: AA94-048-120) is the direct OEM solution for restoring the mechanical action of your K-3000 torch. Unlike aftermarket imitations that may not align perfectly with the torch body or insulator assembly, the genuine Arcair upper arm ensures correct geometry and electrical continuity. It is designed to work seamlessly with the K-3000's spring and insulator systems to provide a firm grip on round or flat electrodes. Proper maintenance of the upper arm and jaw assembly is crucial for preventing air leaks and ensuring the compressed air stream is correctly directed along the electrode for effective metal removal.

Welders Supply recommends inspecting your gouging torches regularly for signs of wear. If the lever action feels loose or the electrode slips during gouging, it is likely time to replace the upper arm. Installation is straightforward for maintenance personnel familiar with the K-3000 assembly. By keeping your torches in top condition with the 94048120 Upper Arm, you protect your investment and ensure the safety and productivity of your welders. This part is compatible with the standard K-3000 torch (01-065-000) and is an indispensable item for any heavy industrial repair kit.
