Same Great Reliability Plus:

  • Dual operator capability
  • Three Phase Power
  • Lower running costs
  • More Weld & Auxiliary Power
  • Vandal Proof Doors
  • Factory Fitted VRD

Dual Operator

Two independent arcs, with up to 400 Amps each. Now two operators can work off one power source.

Lower Running Costs

A dual operator engine drive cuts running costs:

  • Engine Servicing
  • Fuel
  • Compressor Servicing
  • Compliance Testing

Three Phase Power

Run lighting and tools onsite or an XMT Inverter giving you three arcs up to 260 Amps each.

Model Upgrade Options

Reduce mine spec modification costs. Model upgrade packages include: double polarity battery isolator, 'E' stop and/or bash frame and spill tray.

Serious Power

  • 800 Amps of weld output.
  • 27,000 watts of three phase, 415V power (dependent of weld output).
  • 5,500 watts of single phase, 240V power (independent of weld output).

Deutz Turbocharged Engine

Consumes as little as 1.4 L/hour at idle speed.

Lower Capital Investment

Cut initial capital investment costs in half by reducing the number of engine drives in a standard fleet.

Vandal Proof Doors

For onsite security.

Infinite Arc Control

Change the arc characteristics for specific applications in Stick, MIG and FCAW.

Ingersoll Rand Compressor

Ultra-reliable Ingersoll Rand industrial rotary screw compressor has a life expectancy of 30,000 hours, resulting in longer service intervals.

Increased Efficiency

More arcs and better fuel economy equal increased profits for your business. Estimated savings are 34 percent with a dual-operator unit versus two single-operator units.

Electronic Engine Display

Simultaneously displays fuel level, engine hours, coolant temperature, oil pressure, battery volts, engine RPM, air pressure, and compressor hours. Also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.

VRD Standard (Cat.C AS1674.2)

Reduces the open-circuit Voltage to 15 Volts when the welding power source is not in use, increasing operator safety without compromising arc starts.

Auto Remote Sense

(ARS) detects if a remote control is plugged into the 14-pin receptacle and eliminates confusion of a remote/panel switch.

Thermal Overload Protection

Prevents machine damage if the duty cycle is exceeded or airflow is blocked.

Standard Features

  • Digital weld meters.
  • Automatic idle.
  • Anti Vandalism Kit.
  • Lockout/tagout battery disconnect switch.

Auxiliary Power

  • 1 x 380 V 32 Amp Sockets.
  • 2 X 240 V 15 Amp Sockets.
  • RCD.

Generator auxiliary power is 60Hz, and intended for operating equipment associated with welding, such as angle grinders, drills and floodlights. Some Australian 50Hz equipment incorporating induction motors, such as pumps, fans, air compressors, refrigeration or air-conditioners, may not operate correctly and could be damaged. Refer to appliance supplier or manufacturer to confirm suitability.
