Miller Enterprises 18V 350 A Water-Cooled TIG Torch Body

SKU CH-4H41-771VW MPN 18V

Water-cooled TIG torch body rated for 350 A at 100 percent duty cycle with a rigid neck for 5/32 in. electrodes

  • TypeWelding Parts & Supplies
  • Continuous 350 A output with 100 % duty cycle
  • Water-cooled design handles sustained high-amperage TIG work
  • Rigid neck gives precise control on aluminium and exotic metals
  • Accepts electrodes up to 5/32 in for thick-section welding
  • Built for shipbuilding, pressure-vessel and heavy-fabrication environments

Application Suitability

The Miller Enterprises 18V torch body is a water-cooled TIG welding component rated for 350 A at a 100 percent duty cycle. Its rigid neck and 5/32 in maximum electrode capacity suit aluminium fabrication, ship repair, automotive work and general metal fabrication. Professional welders gain a durable tool for continuous high-amperage TIG welding (GTAW) across heavy manufacturing and pressure vessel projects.

Cooling Requirement

This body suits operators who already have or can install a water-cooling system for the torch. It will not suit workshops limited to air-cooled equipment or buyers who need a flexible neck for tight joint access. The rigid design also limits manoeuvrability compared with flexible-neck alternatives.

Current Rating

The 350 A maximum current at 100 percent duty cycle is the decisive specification. Match this rating to your power source output and the joint demands; if the application requires higher amperage or a different cooling method, a different torch body is needed.

Questions about this item

What mounting interface does the 18V torch body use to connect to a water-cooled TIG power source?

The 18V body uses the standard WP-18 series mechanical fitting and water, gas, and power connections compatible with 350 A water-cooled TIG systems.

How is the rigid neck positioned during installation, and what step avoids coolant leaks?

The rigid neck is fixed; install the body onto the power source, connect water inlet and outlet hoses securely, then pressurise the cooling system to check for leaks before welding.

Which consumables for the 18V body must be replaced when the 5/32 in. electrode maximum is reached or the 100 % duty cycle drops?

Replace the collet, collet body, gas lens, and ceramic cup when they show wear or when you change to a different electrode size up to the 5/32 in. limit.
