Arc Liquid-Cooled Mig Set-up Guide

Core Technologies

Bi-Flow2 Technology

Lighter and cooler running torches with increased power to weight performance ratios

NRS Technology

Trouble free fitting and removal of the nozzle with a highly efficient transfer of heat between the base of the nozzle and the dual circuit chamber

SIC Technology

Accumulated spatter breaks free when the nozzle is released

OSW Technology

From drive roll to contact tip every small detail that affects soft wire welding has been considered

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

Nozzle, tip adaptor and contacts tips are all force cooled.

Nozzle Retention System
NRS Technology combines a Liquid-Cooled nozzle seat and a push-on nozzle with a threaded retention system.

The design solutions force cool the nozzle, aid spatter removal and increase front-end wear parts durability.

Spatter Isolation Chamber

A uniquely designed spatter “well” accumulates molten metal particles safely and works in conjunction with the nozzle retention system for trouble free removal of the nozzle and spatter ring.

Optimized for Soft Wire Welding

Technical design solutions have resulted in a more efficient delivery of the filler metal from the machine to the torch head.

  • Smooth transfer of the filler metal from the drive rolls to the tip
  • Improved laminar gas and reduced downtime from ‘post weld clean up’

Key Elements

Wear Parts

Superior performance wear parts have pushed the performance levels way beyond currently accepted norms

Swan Necks

Cooler running torches with increased power to weight performance ratios

Handle Sets

Control of simple machine commands via analogue switches from the torch handle


From drive roll to contact tip every small detail that affects soft wire welding has been considered

Cable Sets

Clever material selection combines flexibility, durability and performance

Key Benefits

  • Large area tapered face on contact tips improves current transfer.
  • Insulator ‘snap fits’ onto the tip adaptor.
  • A 360° turn on the nozzle ring forces the nozzle forward and breaks off accumulated spatter.
  • All wear parts are laser marked for ease of identification.

Key Benefits

  • Double circuit conductor and nozzle seat cooling
  • Overmoulded body armour for improved insulation and impact strength
  • Neck ridges provide ‘finger grip’ under the welders glove

Key Benefits

  • The easiest system to integrate and suitable for after-market torch replacement of OEM products
  • Welding parameters can be changed via ‘Plug and Play’ 2 or 4 way control modules
  • Signals are sent through a 5-core switch lead and separate control plug


  • Utilizes air gap technology, isolating radiated heat for cooler running handles
  • Standard and retrofit pistol grip handles

Key Benefits

  • Soft wire liners for aluminium, aluminium alloy and copper alloy wires
  • Combi-liners for heavy duty aluminium welding, stainless steel, stainless steel metal core and flux core wires
  • Steel liners for steel wire, steel metal core and flux core wires
  • Optional stainless steel liners for high deposition stainless wire applications

Key Benefits

  • Power cables utilize superior grade copper conductors for added protection against poor water quality and contaminants
  • Specified and constructed to last over 1 million flexes in life cycle testing
  • Modular designed housing allows exit easy cable reconfiguration
