OVERVIEW

Precision Gas Control for Superior TIG Welds

The Weldcraft 49V28 Gas Lens, 1/4" (6.4mm) is an essential upgrade for professional fabricators utilizing the heavy-duty 27A and 27B series TIG torches. In the realm of Gas Tungsten Arc Welding (GTAW), the quality of your shielding gas coverage is directly proportional to the quality of the finished weld. Standard collet bodies often allow shielding gas to exit the nozzle in a turbulent, chaotic manner. This turbulence can draw in atmospheric air—oxygen and nitrogen—which contaminates the weld pool, leading to porosity, oxidation, and weak joints. The 49V28 Gas Lens solves this problem through engineering precision.

At the heart of this component is a multi-layer stainless steel mesh screen system housed within a durable brass body. As the shielding gas passes through these screens, the flow is rectified and smoothed out, emerging from the nozzle as a coherent, laminar column. This stable stream of gas provides a much more robust shield around the molten puddle, even in drafty shop conditions where standard nozzles might fail. For welders working with reactive metals such as titanium, stainless steel, or aluminum, this enhanced protection is critical for achieving X-ray quality results.

One of the most significant operational benefits of using the 49V28 Gas Lens is the ability to extend the tungsten electrode. Because the gas column remains coherent for a greater distance after leaving the nozzle, welders can stick the electrode out significantly farther—often up to an inch or more depending on the cup size—without losing shielding coverage. This feature is invaluable when welding inside deep corners, V-grooves, or complex geometries where the nozzle cup would otherwise obstruct the view or hit the workpiece. By improving visibility and access, the 49V28 not only improves weld quality but also reduces operator fatigue and frustration.

Designed specifically for the 27 series torches, this gas lens ensures a perfect fit and optimal electrical conductivity. It is a small investment that yields substantial returns in weld appearance, structural integrity, and gas efficiency.

  • Tool and Die Repair: Improves visibility for intricate repairs on complex molds.

FAQ

The main benefit is the creation of laminar gas flow. This smooths out the shielding gas stream, reducing turbulence and allowing for better weld pool protection and longer tungsten stick-out.

The 49V28 is designed specifically for use with Weldcraft 27A and 27B TIG torches.

Yes, the gas lens replaces the standard collet body in your torch assembly. You may also need a compatible gas lens nozzle (cup) to fit over it.

The 49V28 has a bore size of 1/4 inch (6.4mm), which dictates the size of the tungsten electrode or collet it can accommodate (though typically the gas lens size refers to the tungsten diameter it supports, please verify your tungsten size matches). *Note: In some contexts, 1/4" might refer to the orifice, but standard naming conventions usually link part numbers to tungsten size. Ensure compatibility with your specific setup.*

Yes, gas lenses are excellent for aluminum welding as they provide a wider, more stable area of cleaning action and shielding.

This product is sold as a single unit (1 per package).

Often, yes. Because the laminar flow is more efficient and less prone to being disturbed by cross-drafts, you can sometimes reduce your CFH (cubic feet per hour) settings while maintaining adequate coverage.

No, the 49V28 is specific to the 27 series. Torches like the 17, 18, and 26 use different series of consumables (typically 45V series gas lenses).
