E300 3+2 Multi-Operator Paks

E300 3+2 Multi-Operator Paks

Top Features

  • 2,000 Watts, 115 VAC Auxiliary Power per Module
  • Available in 4Pak and 6Pak Configurations
  • Built to Red-D-Arc Extreme-Duty Specifications
  • Arc Force, Hot Start, Continuous Output Control
  • Full Remote Control Capabilities
  • Processes: Stick (SMAW), MIG (GMAW), Multiprocess, Multioperator, Air Carbon Arc Cutting, Flux-Cored (FCAW)

The highly efficient design of the E300 3+2 permits the 4Pak version to be operated with a 60 amp service and the 6Pak version from a 100 amp service with either 460V or 575V 3 phase power. With up to 350 amps of DC welding current, full welding output controls, 115 VAC auxiliary power for tools, compact size, and multi-process capability, these Paks are the ideal choice for multiple operator use.
