The Generic 41V35 Medium Back Cap is an essential consumable for welders using the popular 9 and 20 series TIG torches. Designed to meet standard industry specifications, this back cap serves as a direct replacement for the Weldcraft 41V35 and compatible models. It plays a critical role in the TIG torch assembly by applying pressure to the collet, which in turn secures the tungsten electrode in place. This medium-sized variant is often preferred by welders who need a balance between the compactness of a short cap and the electrode capacity of a long cap.
Constructed from high-quality, heat-resistant phenolic material, this back cap is built to withstand the thermal stresses of continuous welding operations. Whether you are operating an air-cooled WP-9 torch or a water-cooled WP-20 torch, this component maintains its structural integrity and prevents thread deformation. The inclusion of a high-quality O-ring is vital for maintaining the shielding gas envelope; it creates a positive seal against the torch body to prevent atmospheric contamination (porosity) in your welds.
This back cap is engineered for versatility, fitting a wide range of TIG torch models including the WP-9, WP-20, WP-25, and their equivalents (HW-20, HW-9). It is rated for the full amperage range of these torches, supporting up to 250 amps in water-cooled applications. The medium length allows for the use of tungsten electrodes that have been sharpened multiple times but are not yet short enough to require a short back cap, maximizing the lifespan of your expensive tungsten consumables.
