OVERVIEW

Optimize Your Torch Setup with the Weldcraft 41V35 Medium Back Cap

Every TIG welder knows the struggle: you are trying to weld inside a roll cage, a manifold collector, or a tight corner of a stainless box, and your torch just won't fit. The standard long back cap keeps hitting the obstruction, forcing you to change your angle and compromise the weld. On the other hand, switching to a short button cap means you have to take your perfectly good tungsten and snap it down to a tiny stub, wasting valuable material and time. The Weldcraft 41V35 Medium Back Cap is the solution to this common headache. It is the "Goldilocks" of torch accessories—not too long, not too short, but just right for versatile fabrication work.

Designed to fit the popular WP-9 air-cooled and WP-20 water-cooled torches, this medium cap reduces the overall length of your torch handle, giving you that extra inch or two of clearance you need to maneuver comfortably. Unlike the button cap, which requires a tiny piece of tungsten, the medium cap allows you to use a decent length of electrode (approximately 3 inches), so you aren't constantly running to the grinder or throwing away half-used rods. It is the perfect upgrade for pipe welders, motorsports fabricators, and maintenance techs who encounter awkward welding positions daily.

When you buy Weldcraft, you are buying the industry standard for quality. Cheap generic caps often have poorly molded threads that can strip out your torch head or brittle plastic that cracks the first time you drop the torch. These 41V35 caps are made from durable, heat-resistant material that stands up to the abuse of a busy shop. They screw in smoothly and tighten down securely, ensuring your collet grips the tungsten firmly for stable arc starts. Plus, the high-quality O-ring ensures you don't get any mystery gas leaks ruining your weld appearance.

This convenient 2-pack ensures you always have a backup. Back caps are easy to lose, and O-rings eventually wear out or get nicked. By keeping a spare 41V35 in your kit, you ensure that a small plastic part never shuts down your production. Whether you are welding at 50 amps on thin aluminum or 250 amps on heavy plate, these caps deliver the reliability and clearance you need to lay down perfect beads.

FAQ

The 41V35 medium back cap is compatible with 9 Series (air-cooled) and 20/25 Series (water-cooled) TIG torches, including models WP-9, WP-20, HW-20, and equivalent torches from other major brands.

This product is sold as a package of 2 medium back caps.

Yes, each 41V35 back cap in the package comes with a factory-installed O-ring to ensure a proper gas seal.

A medium back cap offers a balance between accessibility and tungsten life. It allows you to fit into tighter spaces than a long cap permits, but lets you use longer tungsten electrodes than a short button cap, reducing waste.

The cap is constructed from a high-temperature phenolic compound designed to resist heat and impact while providing electrical insulation.

Yes, the 41V35 is designed to handle the heat associated with the amperage ratings of WP-20 torches, which are typically rated up to 250 amps.

No, the WP-17, WP-18, and WP-26 torches use the 3 Series consumables (like the 57Y02 cap). The 41V35 is specifically for the smaller 2 Series (9/20) torches.

You will need to cut a standard 7-inch tungsten electrode roughly in half (to about 3-3.5 inches) to fit inside the medium back cap.
