9SS19259-1 - Lincoln Electric LA-17 TIG Torch Body Replacement with Gaskets

OEM Quality Replacement for Lincoln TIG Systems

The Lincoln Electric 9SS19259-1 is a genuine OEM replacement torch body designed specifically for the LA-17 series of air-cooled TIG torches. As a critical component of the welding assembly, the torch body serves as the structural and electrical hub for the tungsten electrode, collet, and gas nozzle. This particular unit is engineered to meet the rigorous manufacturing standards of Lincoln Electric, ensuring seamless integration with compatible power sources and torch cable assemblies. The body is constructed from high-grade copper alloys to facilitate efficient current transfer while minimizing resistive heating, a crucial factor in maintaining the 150-amp duty cycle rating typical of the 17-series classification.

One of the primary failure points in TIG torches involves the degradation of insulating materials and gas seals. This replacement body comes pre-fitted with the necessary gaskets, addressing common issues such as shielding gas leakage and atmospheric contamination of the weld pool. The insulation is composed of durable, heat-resistant silicone rubber that protects the operator from electrical shock and withstands the high radiant heat generated during the welding process. The threading on the head is precision-machined to accept standard 17-series consumables, including collet bodies, gas lenses, and alumina cups, ensuring that operators can continue to use their existing inventory of TIG accessories.

For industrial MRO applications, utilizing OEM parts like the 9SS19259-1 is essential for maintaining equipment warranty compliance and operational safety. Generic replacements may suffer from poor tolerance control, leading to thread stripping or poor electrical contact, which can cause arc instability and overheating. This Lincoln Electric torch body restores the LA-17 torch to factory specifications, providing a reliable solution for maintenance teams repairing welding equipment in fabrication shops, automotive repair facilities, and manufacturing plants.
