K960-2 - Lincoln Electric K960-2 Small Twist Mate TIG Adapter with Separate Gas Hose

Technical Overview of the Lincoln Electric K960-2 Adapter

The Lincoln Electric K960-2 Small Twist Mate™ Torch Adapter is a critical accessory for professional welders utilizing compact inverter power sources. Designed to bridge the gap between specific power output configurations and standard TIG torch cabling, this adapter enables the connection of PTA-9V and PTA-17V torches (specifically those with 1-piece cables) to welding machines that utilize a solid 25mm Dinse® style receptacle. This is particularly relevant for machines like the Invertec® V155-S and the Elevate™ SLi, which are engineered for portability and often require external gas management.

In standard TIG welding setups, the gas and power may flow through a single line or separate lines depending on the machine's internal architecture. The K960-2 addresses scenarios where the power source does not support gas-through-connector functionality. It features a solid male 25mm Twist Mate connector that plugs securely into the welder's negative output terminal to establish the electrical arc current. Simultaneously, the adapter provides a separate gas route via an included 6-foot gas hose. This hose bypasses the machine entirely, connecting directly to your argon flowmeter or regulator, ensuring a consistent shield gas supply to the torch head.

Constructed with high-quality conductive materials and durable insulation, the K960-2 ensures minimal voltage drop across the connection, maintaining the arc stability required for precision TIG work. It is rated to handle the amperage outputs typical of 9 Series (125 amps) and 17 Series (150 amps) air-cooled torches. The adapter boot is designed to protect the connection point from shop debris and accidental contact, enhancing safety during operation. This component is essential for fabricators who wish to utilize standard, readily available air-cooled torches with valved heads on their portable Lincoln Electric inverters.

By utilizing the K960-2, operators can expand the versatility of their stick welding inverters, effectively converting them into TIG-capable units (Lift-TIG or Scratch-start, depending on machine logic) without the need for complex internal modifications. It represents a seamless integration of power delivery and gas management in a compact, rugged form factor suitable for industrial maintenance, construction sites, and field repair applications.
