BWSVTR-18 - 18 Series Water-Cooled TIG Torch Body with Gas Valve (350A)

Technical Overview of the VTR-18 Torch Body

The VTR-18 is a specialized replacement torch body designed for the 18 Series TIG torch platform. It is engineered to support high-amperage welding operations, rated at 350 Amps DC and approximately 260 Amps AC. The defining characteristic of this model is the 'VTR' designation, which indicates a Valve, Torch, Rigid configuration. This unit integrates a manual gas control valve directly onto the torch body, providing the operator with direct control over shielding gas flow. This feature is particularly critical for welding power sources that lack an internal gas solenoid or for field applications where simplified gas management is required.

Constructed for durability and thermal efficiency, the VTR-18 utilizes a water-cooling system to dissipate the intense heat generated during heavy-duty welding cycles. The internal water chambers are designed to maximize flow rate and thermal transfer, ensuring the torch handle remains cool even during prolonged use at maximum amperage. The body is insulated with high-dielectric silicone rubber, offering superior resistance to high-frequency voltage leakage and physical abrasion. The rigid neck angle is fixed to standard industry specifications, providing a stable and consistent torch orientation favored in automated or repetitive manual welding tasks.

Compatibility is a key strength of the VTR-18. It accepts standard 18 Series front-end consumables, including collets, collet bodies, gas lenses, and alumina cups (10N and 57N series parts). The rear connections utilize standard threading for water-cooled power cables, water-in hoses, and gas-in hoses, making it a drop-in replacement for most generic and brand-name 18 Series torch assemblies. This component is essential for maintaining the operational integrity of water-cooled TIG setups requiring manual gas intervention.
