Why you should use the Arc T5W

Core Technologies

Bi-Flow Technology

Higher powered performance from a much smaller footprint

Force Cooling Technology

The cooler running collet assembly maximizes conductivity and extends consumable life

HZI Technology

Cooler running torches with increased power to weight performance ratios

TRS Technology

Quick and easy extension of the electrode without the removal of any other wear parts

Increased Capacity Liquid Cooling Systems

Re-engineered high-capacity cooling chambers remove excessive heat at source.

Gas Stream Cooling

A highly effective series of passages and wells force cools the collet.

The cooler running collet assembly maximizes conductivity and extends consumable life.

Heat Zone Isolation Technology

Transferred heat from the ceramic cup is isolated by a unique external barrier.

Conducted heat is isolated using large air pockets within the torch body structure resulting in cooler running torches with increased power to weight performance ratios.

Tungsten Release System

Trouble free extension of the electrode with 180° twist of the back cap.

Key Elements

Wear Parts

Every component delivers superior performance for increased Arc time and lower overall production costs

Torch Bodies and Back Caps

Step change performance levels achieved with the development of revolutionary cooling and heat zone isolation techniques

Handle Sets

Fits seamlessly into the hand. 'Plug and play' switch options for machine control functionality and Point of Sale configuration

Cable Systems

Clever material selection combines flexibility, durability and performance

Key Benefits

  • Push-on / easy grip ceramics
  • One piece collet/collet body – no twisting
  • Heat Zone Isolator ensures 100% ceramic and electrode alignment
  • Optional large gas lens for increased gas envelope

Key Benefits

  • Cooler running torch bodies at elevated power levels

  • Cooler running components increase wear parts life expectancy

  • Advanced material selection and component design enhances flex neck life expectancy

  • Superior grade phenolics for maximum thermal resistance and improved durability of back caps


  • Liquid-Cooled Flex Life > 50 Flexes – Double the life of a standard Liquid-Cooled flex body

Key Benefits

  • Utilizes air gap technology for cooler running handles
  • Hard and soft material elements for an effortless grip
  • Fully interchangeable ‘plug and play’ modules with analogue and digital control options
  • Infinite adjustment of welding parameters from the torch handle
  • Optional integrated handle readout displays all welding and machine parameters in “real time”

Key Benefits

  • Rapid fit and modular rear end systems ensure point of use reconfiguration of power input, water/gas hose and control lead terminations

  • Superior grade rubbers ensure cable termination integrity and hose package longevity – (Lab tested to over 1 million flexes)

  • Front end leather cover and knuckle joint combine for a really supple cable at the welders wrist.
