• Arcair gouging carbons are used for the efficient gouging, back gouging, plate edge preparation, touching up and removal of old or defective hardfacing and stainless steel weld deposits
  • Used for reworking plates, dies, castings, pipes, armour plating etc
  • They gouge and sever ferrous and non-ferrous metals such as carbon steel, low alloy steel, stainless steel, cast iron, nickel alloys (nickel less than 80%), magnesium alloys and aluminium on DCEP Copper alloys, aluminium bronze alloys and aluminium nickel bronze alloys can be gouged using DCEN


General Arcair Gouging Carbons as used for the efficient gouging, back gouging, plate edge preparation, touching up and removal of old or defective HardFacing and stainless steel weld deposits.
Applications Used in many industries such as agriculture, automotive, heavy fabrication, construction, foundries, maintenance and repair shops, mining and quarrying, military, shipyards, power plants, railroads,

  • Reliable torch design – market leader for over 60+ years
  • Natural 15 degree torch angle – greater operator comfort
  • Positive grip handle – greater operator feel and ease in positioning torch
  • Durable front insulators – high impact and heat resistant, protects the torch metal parts
  • Swivel cable – less cable twist and less strain on the operator
  • Reduced weight – optimum cable and torch weight to minimize fatigue
  • High quality cable hose – best quality cable hose offers high heat and abrasion resistance, non-conductive
  • Power and air connection fully enclosed – protects the electrical connection from touching the work when in operation and eliminates the need to insulated with electrical tape
