Overview

Extreme performance in a single compact system. This system includes all the power you need on the jobsite to complete your work. This self-contained system is ideal for mechanic’s trucks with electric or electric over hydraulic cranes.  The Compressor-Generator-Welder system can operate electrical equipment, air tools and welding accessories.

Components included:

  • 45 CFM Rotary Screw Air Compressor
  • 8 kW Continuous AC Generator
  • 250 A DC Welder (adjustable)
  • 12-48 V Battery Booster (adjustable)
  • 12-48 V Battery Charger (adjustable)
  • Factory-installed Cold Climate Kit – 120 V, tested to -40°F (-40°C)

Applications – Common jobs that use the Compressor-Generator-Welder Power System:

  • Mobile heavy duty mechanics
  • Welding trucks
  • Heavy equipment repair technicians
  • Remote access jobs in mining, logging and oil & gas

Components

AIR COMPRESSOR

High airflow, 100% duty cycle with the reliability of the global leader in mobile compressed air.

WELDER

Multi-process welding including gouging, constant current, constant voltage and the ability to run a suit-case style wire feeder.

BATTERY CHARGER

Keep your customers up and running with a mobile battery charger.

BATTERY BOOSTER

Boost anything from a car to a haul truck.

GENERATOR

Proven mobile power solution to run your electronic equipment and electric tools.

COLD CLIMATE PROTECTION FOR -40º

Cold Climate Protection recommended if ambient temperatures frequently drop below -10C (14F). Combine with optional 1000W inverter and warm the system on the way to the job site.
