DESCRIPTION
A long back cap is an essential TIG torch accessory that screws into the rear of the torch body, holding the tungsten electrode securely and sealing the torch. The "long" version provides maximum reach and allows for the use of full-length (e.g., 150 mm) tungsten electrodes without trimming. It is commonly used for general TIG welding where maximum flexibility and access are not restricted.
