Core Technologies

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

Spatter Isolation Chamber

Spatter created by the arc is held within a unique chamber that collects the molten metal droplets

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

Exacting component design improves performance to weight ratios and wear parts durability

Swan Necks

Cutting edge material selection push the boundaries of established swan neck design

Handle Sets

Control of simple welding parameters via the torch handle by interfacing 2 & 4 way digital control modules

Liners

Developed from in-depth studies of wire types, process and gas coverage

Cable Sets

Improvements in welder comfort and reductions in welder fatigue

Key Benefits

  • Contact Tips made from CuCrZr with M8 thread
  • Increased area pick up points on contact tips reduce power loss and improve current transfer
  • Left hand threaded tip adaptors negate accidental removal when spatter is embedded at the base of the nozzle
  • All wear parts are laser marked for ease of identification

Key Benefits

  • High tech polymers for improved insulation properties, impact strength and weight reduction
  • Neck to handle interface minimizes transfer of conducted heat to the handle
  • Neck ridges provide ‘finger grip’ under the glove

Key Benefits

  • Welding parameters can be changed via ‘Plug and Play’ 2 or 4 way control modules
  • Torch and machine are digitally interfaced via the switch leads and gun plug body pins

  • Utilizes air gap technology, isolating radiated heat for cooler running handles
  • Knuckle joints and short cable support systems for improved positioning

Key Benefits

  • Steel liners for steel wire, steel metal core and flux core wires
  • Combi-liners for aluminum, stainless steel, stainless steel metal core and flux core wires
  • Unique sealing ring solution for effective sealing from impurities in argon gas processes

Key Benefits

  • New cable structures for improved flexibility and weight reduction
  • SuperSoft -20 Premium power cables, perfect for extreme subzero working temperatures, and up to 40% lighter than standard cables
  • Specified and constructed to last over 1 million flexes in life cycle testing
