JW Signature Series TIG 350 High-Purity TIG Torch Package

Premium Rigid Head 350 Amp Water-Cooled Torch Package. Compact torch body with 25' (7.6m) SuperFlex™ Power, water hoses & SuperGasHose™ Non Permeable High-density Gas Hose and Proprietary One-Way Gas Flow technology. 

The Highest Quality TIG Welds Guaranteed! 

  • Designed to deliver the highest quality welds with no gas contamination
  • SuperGasHose™ high density matrial will not kink or flatten - ensuring continuous gas flow.  More importantly, the material is non permeable, so it will not aspirate, or draw in atmosphere like rubber gas hoses are proven to do.

SuperGasHose™ Saves Up to 50% on Shield Gas

  • SuperGasHose™ Improves TIG weld quality with Proprietary SuperHose™ material and Proprietary One-Way Gas Flow technology - guaranteed to stop your TIG torch from back filling with atmosphere when you stop welding.
  • SuperGasHose™ saves money on inert gas.  Think about how many times a day you Start and Stop a weld, and how much Argon is being WASTED to purge atmosphere out of your torch leads.
  •  Change fewer gas cylinders saving you time and money!
