KP2166-1 - Lincoln Electric PTA-26 Power Cable Adapter

High-Performance Connectivity for PTA-26 Torches

The Lincoln Electric KP2166-1 One Cable Adaptor is a critical component designed to facilitate the connection of PTA-26 series TIG torches to welding power sources. Engineered specifically for air-cooled applications, this adapter bridges the gap between the torch's single-piece power cable and the machine's output terminals. In a standard one-piece cable system, the electrical current and the shielding gas travel through the same conduit. The KP2166-1 effectively separates these inputs at the machine end, providing a sturdy lug for electrical connection to a stud terminal and a separate hose barb or fitting for the gas supply.

Constructed from high-grade solid brass, the adapter block offers superior electrical conductivity, minimizing resistance and heat buildup even during prolonged welding sessions at the torch's rated 200-amp capacity. The brass body is encased in a durable, heat-resistant rubber boot that provides essential insulation, preventing accidental arcing or short circuits against the machine case or other conductive surfaces. This attention to material quality ensures that the adapter maintains a stable arc and consistent voltage delivery, which is paramount for precision TIG welding.

Installation of the KP2166-1 is straightforward and secure. The threaded receiver accepts the standard connector found on PTA-26 one-piece power cables, creating a gas-tight seal that prevents shielding gas leaks—a common cause of porosity in welds. The integrated gas hose extends from the block, allowing for easy attachment to the solenoid or flowmeter output on the welding machine. By using genuine Lincoln Electric parts like the KP2166-1, operators ensure full compatibility with their equipment, maintaining the safety and performance standards set by the manufacturer.

This adapter is an essential accessory for welders upgrading their torch setup or replacing worn connection components. It allows for the versatile use of the robust PTA-26 torch on a variety of Lincoln Electric power sources that utilize a stud-style output, ensuring that your welding operations remain efficient and adaptable to various fabrication requirements.
