Set-Up Guide

Key Elements

Wear Parts

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

Liners

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

Cable Sets

Clever material selection combines flexibility, durability and performance

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

  • 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

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

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’
