Additional Features

Wind tunnel technology protects electrical components and PC boards from contamination. Fan-On-Demand cooling system operates only when needed reducing noise, energy use and amount of contaminates pulled through the machine. Lift-Arc allows TIG starting without the use of high-frequency. Adaptive Hot Start increases the output amperage at the start of the weld if necessary, eliminating electrode sticking. Line voltage compensation keeps power constant even if power varies by +/- 10%. Process selector switch reduces the number of control setup combinations without reducing any features. Dual digital meters are included. 115 VAC auxiliary power.

Voltage Input
Individual Units: Auto-Line Power Management Technology allows for operation with any type of primary power from 208 to 575 VAC, single- or three-phase, 50 or 60 hertz, with no manual linking required - ideal for dirty or unreliable input power. 4Pak and 8Pak Multioperator units include DP120 Panels and operate with 460/575/3/60 input power.

Features

  • CC/CV welding processes with full remote-control capability
  • Auto Remote Sense enables unit to automatically use remote control if connected to remote control receptacle
  • Potentiometer-type remote control
  • Exceptional electrical efficiency (87.24% efficiency at 400A)
  • Power factor of .95 enables smaller fuses/breakers and primary wiring
  • Selectable Low-OCV Stick mode reduces open circuit voltage to nearly 15 volts when welding power source is not in use
  • Extreme-Duty environmental protection with ultra-tough, poly carbonate-blended control panel cover
  • Tweco style output terminals
  • Wind Tunnel Technology protects electrical components and PC boards from contamination
  • Line Voltage Compensation keeps welding output constant with power variations of +/- 10%
  • CSA certified to both U.S. and Canadian Standards for welding equipment
