OVERVIEW

Keep Your Fronius Torch Running Smoothly

Every TIG welder knows the frustration of a cracked or lost back cap right in the middle of a job. The Fronius Medium Back Cap L64 (44.0350.0337) is the reliable replacement you need to get your rig back up and running. Designed to fit the popular Accupocket 1600 and the widely used TTG and TTW torch series, this cap is the workhorse of the TIG accessory world. It provides the perfect balance for your setup, allowing you to use standard-length tungsten electrodes without adding unnecessary bulk to the back of your torch handle.

Why choose the medium cap? It's all about versatility. When you are welding in a relatively open area but still need to maneuver around fixtures or jigs, the long cap can sometimes get in the way. The short cap is great for tight spots but forces you to snap your expensive tungsten in half. The Medium L64 cap sits right in the sweet spot. It gives you enough room to consume a good portion of your electrode before needing a fresh grind, but it stays out of your way when you are manipulating the torch in out-of-position welds.

This cap is built tough. We know that torch parts take a beating—they get dropped, tossed on tables, and exposed to high heat. This replacement part is made from high-quality impact-resistant material that resists cracking and thread damage. It screws on smoothly to the back of your TTG1200A, TTG2200A, TTW2500A, or TTW3000A torch, locking your tungsten firmly in place for a steady, flutter-free arc. A loose tungsten or a gas leak at the back cap can ruin a perfect bead; don't let worn-out consumables hold you back.

Whether you are working on precision stainless steel, aluminum fabrication, or general repairs with your Accupocket, having a fresh back cap ensures your shielding gas goes exactly where it's supposed to—the weld pool. Don't wait until your current cap fails. Keep a spare 44.0350.0337 in your kit and ensure your Fronius torch is always ready for the next arc start.

FAQ

This back cap (44.0350.0337) is designed for Fronius torches including the Accupocket 1600, TTG1200A, TTG2200A, TTW2500A, and TTW3000A.

A medium back cap (L64) is shorter than a long cap, allowing for better access in tighter spaces while still accommodating a reasonable length of tungsten electrode compared to a short cap.

Most TIG back caps rely on an O-ring for sealing. While the O-ring is typically included on the cap assembly, it is always good practice to check if your specific package includes a spare or if the pre-installed one is intact.

This product is identified by the Fronius part number 44.0350.0337. Please check the specific listing details to confirm if it is a genuine OEM part or a high-quality aftermarket replacement compatible with Fronius systems.

If you notice gas leaking from the back of the torch, if the threads are stripped, or if the cap is cracked (often from dropping the torch), it needs to be replaced immediately to prevent weld contamination.

Yes, this cap fits the TTW2500A and TTW3000A, which are water-cooled Fronius TIG torches.

Usually, a medium back cap cannot hold a brand new full-length 7-inch tungsten. You typically need a long cap for that. The medium cap requires the tungsten to be cut down slightly or used after it has been ground down from previous use.

TIG back caps are generally made from a high-temperature phenolic or plastic compound to insulate the welder from the electrical current and withstand the heat of the torch head.
