KP2034-1B1 - Lincoln Electric .020 Gas Lens Collet Body for 9/20 Series Torches

Optimize Your TIG Welding with Lincoln Electric Gas Lenses

The Lincoln Electric KP2034-1B1 Gas Lens is a premium consumable designed to elevate the performance of your TIG welding torch. Specifically engineered for use with .020 inch (0.5 mm) tungsten electrodes, this gas lens replaces standard collet bodies in 9, 20, and 25 series torches. By incorporating a fine mesh screen, the gas lens transforms the turbulent flow of shielding gas into a coherent, laminar stream. This improvement is critical for welders seeking the highest quality results, particularly when working on delicate or thin-gauge materials where precision is paramount.

Why Choose a Gas Lens?

Standard collet bodies often produce a turbulent gas pattern that can pull atmospheric air into the weld zone if the torch is lifted too high or angled aggressively. The KP2034-1B1 solves this by smoothing out the gas flow. This laminar coverage allows you to extend the tungsten electrode further past the nozzle—known as "stick-out"—without sacrificing shield integrity. Increased stick-out provides significantly better visibility of the weld puddle and allows access into tight corners, fillets, and complex geometries that would otherwise be difficult to reach.

Lincoln Electric Quality

Manufactured to Lincoln Electric's exacting standards, this gas lens ensures consistent electrical conductivity and heat transfer. It is an essential upgrade for fabricators working with stainless steel, titanium, or aluminum, where gas coverage is directly linked to weld appearance and structural integrity. Whether you are using a PTA-9, PTA-20, or PTW-20 torch, the KP2034-1B1 integrates seamlessly into your existing setup, requiring only a compatible gas lens nozzle to complete the assembly.
