The ESAB Heliarc 34015 medium torch cap is a precision replacement consumable for air and water-cooled TIG welding torches. This medium back cap is suitable for use with Genuine Heliarc HW-17, HW-18 and HW-26 TIG torches. The medium-length back cap holds the tungsten in place and includes an installed O-ring seal, ensuring consistent arc starts and reliable electrode retention during production welding. The product comes packaged with 2 caps per bag, providing stock for backup or multiple torch setups.
Key Features
