K2166-2 - Lincoln Electric Adapter for PTA-9/17/26 Two-Cable Torches

Lincoln Electric K2166-2 Two-Cable Torch Adapter

The Lincoln Electric K2166-2 Two-Cable Adapter is a specialized accessory designed to enhance the versatility of the Precision TIG welding machine series. In industrial welding environments, equipment flexibility is paramount. This adapter serves a critical function by converting the standard 7/8-inch water and power connection found on Precision TIG units into a universal 1/2-inch output stud. This conversion is essential for operators who wish to utilize two-cable air-cooled TIG torches, specifically the PTA-9, PTA-17, and PTA-26 models, which are staples in light to medium-duty fabrication.

Constructed with the durability expected from Lincoln Electric, this adapter ensures a secure and conductive path for welding current, minimizing voltage drop and ensuring arc stability. The unit is engineered to withstand the rigors of daily shop use, featuring robust threading and high-quality conductive materials. By installing this adapter, users can bypass the limitations of proprietary or water-cooled specific connections, opening up a wider range of torch options for specific welding applications.

Installation is straightforward, requiring minimal downtime. The adapter screws directly into the machine's power block, providing a sturdy lug connection point for the power cable of a two-cable torch assembly. This is particularly useful in scenarios where water cooling is unnecessary or unavailable, allowing the Precision TIG power source to be adapted for portable or lower-amperage air-cooled tasks. Whether for maintenance, repair, or production welding, the K2166-2 is a vital component for managing torch inventory and machine compatibility.

Key Technical Benefits:

• Seamless Conversion: Transforms 7/8" machine ports to standard 1/2" studs.
• Broad Compatibility: Fits industry-standard PTA-9, 17, and 26 series torches.
• Reliable Power Transfer: Designed to handle the amperage ranges associated with compatible air-cooled torches without overheating.
