Licensed welders and fabrication shops rely on properly fitted adapters to maintain arc stability and prevent connection failures during high-heat, precision welding work.
This adapter is compatible with HW-17, HW-20A, and HW-20AF TIG torch models. It is suited for professional welding environments including fabrication shops, maintenance and repair operations, and field service work where ESAB TIG torches are in use.

Installation should be performed by a qualified welder or welding equipment technician. Always disconnect the welding power source completely before servicing torch components or replacing cable adapters. Inspect the mating connector surfaces for wear or damage before installing the new adapter. Follow the torch manufacturer's assembly guidelines to ensure a proper mechanical and electrical connection before returning the unit to service.
