OVERVIEW

Weldcraft Short Back Cap for CS310 Torches – 2 Pack

When your TIG welding job demands precision in tight quarters, the Weldcraft CS110-BCS Short Back Cap is the accessory you need in your kit. Designed for the heavy-duty Crafter Series 310 (CS310) and W-310 water-cooled torches, this short back cap transforms the profile of your torch. Standard long back caps are excellent for holding full-length tungsten, but they can be a hindrance when you are welding inside a manifold, a roll cage, or a tight pipe cluster. This short cap allows the back of the torch to clear obstructions that would otherwise make the weld impossible.

This convenient 2-pack ensures you always have a spare in your toolbox. TIG back caps are subject to heat stress and mechanical wear, and the threads can eventually degrade or the cap can be dropped and cracked. Having a backup ready means you don't have to stop your work to source a replacement. Furthermore, each cap includes the essential 98W77 O-Ring. A fresh O-ring is critical for preventing atmospheric contamination of your shielding gas. If you are experiencing unexplained porosity or your tungsten is turning black/blue despite good gas flow at the regulator, a faulty back cap seal is often the culprit.

Usage Note: Because this is a short back cap, it requires the use of shorter tungsten electrodes. You will need to cut your tungsten down to size to fit within the shallow depth of the cap. This is a standard trade-off for the massive gain in maneuverability and access provided by the CS110-BCS. Trust genuine Weldcraft components to withstand the high amperage heat associated with the CS310 series torches and to provide the reliable performance professional welders expect.

Features & Benefits:

  • Access Tight Spots: Reduces torch length significantly compared to long caps.
  • Secure Fit: Precision threads prevent cross-threading on your expensive torch body.
  • Gas Integrity: High-quality O-ring ensures a hermetic seal for pure argon coverage.
  • Value Pack: Includes two caps per order.

FAQ

The CS110-BCS is designed specifically for the Weldcraft Crafter Series 310 (CS310) and the W-310 water-cooled TIG torches.

This product is sold as a pack of 2. You will receive two short back caps.

Yes, each CS110-BCS back cap includes the 98W77 O-Ring already installed.

No, because the cap is short, you must cut your tungsten electrode down to a shorter length to fit inside the cap.

A short back cap reduces the overall length of the torch, making it much easier to weld in tight spaces or awkward angles where a long cap would hit obstructions.

Yes, this is a genuine Weldcraft (Miller Electric) replacement part, ensuring proper fit and safety.

The replacement O-ring for this back cap is part number 98W77.
