K960-1 - Lincoln Electric K960-1 Twist Mate TIG Torch Adapter (Separate Gas)

Technical Overview of the Lincoln K960-1 Adapter

The Lincoln Electric K960-1 Twist Mate Torch Adapter is a specialized interface component designed to facilitate the connection of specific air-cooled TIG torches to welding power sources utilizing Twist Mate receptacles. Specifically engineered for use with PTA-9 and PTA-17V torch models equipped with 1-piece power cables, this adapter addresses the mechanical and pneumatic requirements of systems where the power source does not provide shielding gas through the output terminal.

In standard TIG welding configurations involving 1-piece cables, the electrical current and shielding gas flow through a single conduit. However, many power sources—particularly those designed primarily for SMAW (Stick) welding or basic DC TIG—utilize Twist Mate (Dinse-style) connectors solely for electrical output. The K960-1 adapter resolves this incompatibility by providing a robust Twist Mate male connector for the machine side, while simultaneously offering a receiving port for the torch's power pin and a separate diversion path or inlet for the shielding gas. This design allows the operator to route gas directly from a flowmeter or regulator to the torch, bypassing the machine's internal plumbing entirely.

Constructed from high-grade conductive brass and durable insulating materials, the K960-1 ensures minimal voltage drop across the connection, maintaining arc stability and welding performance. The unit is rated to handle the amperage capacities typical of the PTA-9 and PTA-17V series torches. The adapter creates a secure mechanical lock with the power source, preventing accidental disconnection during operation, while the gas interface is designed to accept standard gas hose fittings, ensuring a leak-free shield for the weld pool. This component is essential for MRO operations looking to expand the utility of existing power sources to include TIG capabilities using standard, readily available torch assemblies.
