K2166-1 - Lincoln Electric K2166-1 TIG Torch Power Adapter 7/8 to 5/8 Inch

Connect Your PTA-26 Torch with Confidence

When you are setting up a heavy-duty TIG rig, few things are more frustrating than realizing your torch cable threads don't match your machine's output studs. The Lincoln Electric K2166-1 One-Cable Adapter is the definitive solution for welders using the popular PTA-26 series torches. This adapter is designed to bridge the gap between the 7/8-inch fitting on your torch's power cable and the 5/8-inch gas/power connection on your welding machine.

Built for High Amperage
The PTA-26 is a workhorse torch, often used for thicker materials and higher heat applications. You need an adapter that can take the heat without melting down or causing voltage drops. The K2166-1 is rated for up to 320 amps, giving you plenty of headroom for demanding jobs. Its solid construction ensures that power transfer is efficient, keeping your arc stable and your welds clean. Unlike cheap aftermarket adapters that can overheat and fuse to your cables, this genuine Lincoln part is built to withstand the thermal cycles of an industrial shop environment.

Simple Installation, Secure Fit
Installation is straightforward. The adapter screws directly onto the machine's output stud, and your torch cable screws into the adapter. The precision-machined threads ensure a gas-tight seal, preventing shielding gas loss that could lead to porosity in your welds. The hex-shaped body allows you to get a good grip with a wrench, ensuring everything is locked down tight before you strike an arc. Whether you are replacing a worn-out connector or setting up a new machine, the K2166-1 is the reliable link your TIG setup needs.

Don't compromise your weld quality with poor connections. Ensure your gas flow and electrical current are delivered flawlessly to your torch with this essential Lincoln Electric adapter.
