Best Welds 900-45v0204 Gas Lens Collet Body Large Standard

Product Description

The BEST WELDS 900-45v0204 is a large standard gas lens collet body designed for TIG welding applications requiring precise shielding gas control. Compatible with 17, 18, and 26 series torches, this two-piece collet body accepts electrode sizes from 0.020 to 0.040 inches. Constructed from brass and copper, it channels shielding gas through an internal diffuser screen that virtually eliminates turbulence as the gas exits the nozzle. The result is a laminar, stable gas column that improves arc shielding and reduces oxidation at the weld zone. TIG welders use this component when working on materials sensitive to gas coverage inconsistency.

This gas lens collet body is intended for use with 17, 18, and 26 series TIG torches in both shop and field environments. It is commonly installed when upgrading from a standard collet body to a gas lens setup to improve shielding efficiency on stainless steel, aluminum, titanium, and other materials that require clean, consistent coverage. The large standard configuration provides a broader gas envelope compared to a stubby or short-style design, making it well suited for applications where extended tungsten stickout is needed.

Key Features

• Two-piece construction for straightforward assembly and electrode changes
• Eliminates gas turbulence at the nozzle for a stable, laminar shielding stream
• Accepts electrodes from 0.020 to 0.040 inches
• Brass and copper construction for thermal conductivity and corrosion resistance
• Large standard gas lens configuration supports extended tungsten stickout

Compatibility

Designed for use with 17, 18, and 26 series TIG torches. Accepts electrode diameters from 0.020 to 0.040 inches.

Installation Notes

Installation is performed by qualified welding personnel. Before changing collet body components, ensure the welding machine is powered off and the torch has cooled. Thread the collet body into the torch head by hand to avoid cross-threading, then seat it firmly without over-torquing the brass fitting. Verify the correct nozzle and collet are matched to this collet body size before resuming welding operations.
