BWSVTR-17 - Replacement 17 Series TIG Torch Body with Gas Valve - 150A Air Cooled

Technical Overview of the VTR-17 TIG Torch Body

The VTR-17 is a high-quality replacement torch body designed for the widely used 17-series air-cooled TIG torch platform. Engineered to meet industrial standards, this torch body is rated for a maximum output of 150 Amps DC and 115 Amps AC at a 60% duty cycle. It serves as the core structural and conductive component of the torch assembly, connecting the power cable to the front-end consumables. The body is constructed from high-grade copper components to ensure efficient current transfer and minimal heat buildup during prolonged welding operations.

A key feature of the VTR-17 is its integrated gas control valve. This rotary valve is located on the neck of the torch body, allowing the operator to manually open and close the shielding gas flow directly at the torch. This functionality is essential for welding setups where the power source does not possess an internal gas solenoid, common in portable inverter welders or when adapting stick welding machines for TIG processes (scratch-start or lift-arc). The valve mechanism is designed for smooth operation and a positive seal to prevent gas leakage.

The exterior of the torch body is encased in a durable, high-temperature silicone rubber molding. This insulation provides excellent dielectric strength, protecting the welder from electrical shock and high-frequency interference. It also offers resistance to impact and abrasion, extending the service life of the torch in harsh shop environments. The rigid head angle is set to the industry-standard 70 degrees, providing a comfortable ergonomic position for most bench and out-of-position welding tasks. The VTR-17 is fully compatible with standard 10N series consumables, including collets, collet bodies, and alumina cups, as well as 57Y back caps.

Installation is straightforward, utilizing standard threading to mate with 17-series power cables. This unit is an ideal replacement part for maintenance departments and repair operations looking to restore the functionality of existing air-cooled TIG equipment without the expense of replacing the entire torch assembly.
