Pro-source 18 Water Cooled Tig Welding Torch 350A

Product Description

The PRO-SOURCE 18 is a water cooled TIG welding torch rated at 350 amps, designed for high-amperage GTAW (gas tungsten arc welding) applications where sustained duty cycles generate heat that air cooling cannot manage. The body is constructed from silicone rubber, which provides flexibility and resistance to the heat and oil exposure common in production welding environments. At approximately 9 inches in overall length, the torch offers a compact profile suited to work in tighter joint configurations. This torch is installed and serviced by licensed welding technicians and maintenance professionals in fabrication shops, pipe welding operations, and industrial maintenance settings.

The PRO-SOURCE 18 is intended for water cooled TIG welding setups where a recirculating water cooler is already part of the system. It is appropriate for both light industrial and heavy fabrication environments requiring continuous or high duty cycle TIG welding. The 350 A rating supports work on thicker base metals such as heavy plate steel, stainless, and aluminum. No gas valve is included with this torch, so the gas flow must be controlled upstream at the regulator or through a solenoid in the welding power source.

Key Features

• 350 A amperage rating supports high-amperage, high duty cycle TIG welding
• Water cooled design dissipates heat through a recirculating coolant loop rather than the gas stream
• Silicone rubber body construction resists heat, oils, and flex fatigue in production environments
• Compact torch length of approximately 9 inches for access in confined joint areas
• No integrated gas valve — compatible with upstream gas control configurations

Compatibility

Designed as an OEM-style replacement or equivalent TIG welding torch for water cooled GTAW systems requiring a 350 A rated torch body.

Installation Notes

Installation should be performed by a qualified welding technician familiar with water cooled GTAW torch systems. Before connecting or disconnecting the torch, shut off the welding power source and stop the water cooler to relieve coolant pressure in the lines. Verify that all coolant fittings are leak-free before resuming operation, as coolant contamination of the tungsten or work area will disrupt the weld. Follow the welding equipment manufacturer guidelines and applicable AWS safety standards for torch assembly and gas connections.
