OVERVIEW

Lincoln Electric K2166-3 One-Cable Adapter for PTA-9 and PTA-17 Torches

The Lincoln Electric K2166-3 One-Cable Adapter is a critical component for TIG welding setups utilizing air-cooled torches. Designed to facilitate the connection between specific torch models and the power source, this adapter ensures that your equipment operates safely and efficiently. It is specifically engineered to adapt the 3/8-inch connector found on PTA-9 and PTA-17 series torches to the standard 5/8-inch gas and power connection stud found on many Lincoln Electric welding machines. This allows for the seamless transmission of both shielding gas and welding current through a single cable assembly.

Constructed with high-quality materials, the K2166-3 is built to withstand the rigors of industrial environments. It supports torch amperages of 125 A (typical for PTA-9) and 150 A (typical for PTA-17), ensuring that the electrical connection remains stable without overheating during operation. The adapter features precision threading to prevent gas leaks, which is vital for maintaining shielding gas coverage and weld quality. By using genuine Lincoln Electric parts, operators can ensure compatibility with PRO-Torch TIG systems and maintain the integrity of their welding setup.

This adapter is particularly useful for shops that utilize multiple torch sizes or need to adapt lighter-duty torches to heavy-duty machines. The installation is straightforward, requiring standard wrenches to secure the connections. Whether you are replacing a worn adapter or setting up a new torch package, the K2166-3 provides the reliability professional welders demand. It is an essential accessory for maintaining the versatility of your welding fleet.
