OVERVIEW

Thermal Arc 8-2071 Gas Lens Shield Cup Overview

The Thermal Arc 8-2071 is a premium replacement gas lens shield cup designed for professional TIG welding applications. Classified as a #6 size cup, it features a 3/8-inch (9.5mm) orifice, making it an ideal choice for general-purpose welding on stainless steel, aluminum, and mild steel. This component is engineered to work in conjunction with gas lens collet bodies, which smooth out the flow of shielding gas into a laminar stream. This laminar flow significantly reduces turbulence compared to standard collet bodies, providing superior coverage of the weld pool and reducing the risk of atmospheric contamination.

Constructed from high-grade alumina ceramic, the 8-2071 nozzle offers excellent thermal resistance and durability. It is designed to withstand the high heat cycles associated with GTAW processes without cracking or degrading prematurely. The ceramic material also provides electrical insulation at the front of the torch, preventing accidental arcing to the workpiece. This cup is compatible with standard 17, 18, and 26 series TIG torches often supplied with Thermal Arc welding machines.

Using the correct gas lens cup is critical for achieving X-ray quality welds. The 8-2071 ensures that the shielding gas envelope remains stable even with extended tungsten stick-out, allowing welders to reach into tighter corners or maintain better visibility of the arc. This part is an essential consumable for fabricators requiring precision and consistency in their TIG operations.
