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

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.

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

Modular Handle Sets with plug and play control options

Liners

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 to prevent accidental loss.
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

Single circuit with secondary nozzle seat cooling
Reduced weight and maximized cooling
Overmoulded body armour for improved insulation and impact strength
Neck ridges provide ‘finger grip’ under the welders glvoe

Key Benefits

Compact handle design
Utilizes air gap technology, isolating radiated heat for cooler running handles
Minimized handle to torch body interface isolates conducted heat

Key Benefits

Steel liners for steel wire, steel metal core and flux core wires
Stainless Steel liners for high duty steel applications, stainless steel, stainless steel metal core anf flux core wires.
Combi-liners for aluminium, stainless steel, stainless steel metal core and flux core wires
Soft wire liners for aluminium, aluminium alloy and copper alloy wires

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
