05124001 - Arcair N-7500 Replacement Torch Head Assembly

Technical Overview of the Arcair N-7500 Torch Head

The Arcair 05-124-001 is the specific replacement head assembly designed for the N-7500 Angle-Arc manual gouging torch. As a critical component of the heavy-duty gouging system, this head assembly is engineered to manage the high thermal and electrical loads associated with metal removal at amperages up to 1250A. The assembly features robust copper alloy construction, ensuring maximum electrical conductivity and minimal resistance heating during prolonged operation.

This component is responsible for holding the carbon electrode securely while directing the high-velocity air stream parallel to the electrode. The internal geometry is precision-machined to maintain the laminar airflow required to efficiently blow away molten metal. Over time, the extreme environment of the gouging process—characterized by intense radiant heat, molten spatter, and mechanical wear—can degrade the torch head. Replacing a worn head with this genuine OEM part restores the torch's original efficiency, air consumption metrics, and safety standards.

The N-7500 system is typically utilized in foundry and heavy fabrication environments where 1/2-inch to 5/8-inch carbons are standard. This replacement head ensures that the clamping mechanism and air orifices align perfectly with the torch body and handle, preventing air leaks or electrical arcing that could damage the equipment or endanger the operator. It is a direct-fit component requiring no modification for installation.
