Additional Features


  • 3 welding mode selector switch: CV Wirefeed, CC Stick/TIG, and CC Pipe Welding
  • Single, full-range output control dial provides continuous CC current control from 20 amps to 300 amps in the CC Stick/TIG and CC Pipe Welding modes and continuous CV welding arc voltage control from 12 volts to 32 volts in the CV Wirefeed mode
  • Arc control operates in the CC Stick/TIG mode providing adjustment of the short circuit (arc force) current which prevents sticking of the electrode at low welding currents and also operates in the CV Wirefeed mode acting as an inductance control providing a "softer" arc (lower setting) for MIG Welding and a "crisp" arc (higher setting) for Innershield welding
  • 3 pin Amphenol remote control connection, 14 pin Amphenol 42 volt and 115 volt wirefeed connection
  • Output at welding terminals can be switched to "Always On" or "Contactor Controlled" providing convenience and added safety when welding in electrically hazardous conditions
  • Extreme-Duty™ construction includes stainless steel body panels, powder coated protective frames, E-Coat primer on laminations, additional dippings of critical internal components in protective sealants and R.T.V. coated P.C. boards for enhanced protection in harsh environments
  • "Chopper" technology electronic controls provide excellent arc welding characteristics
  • Engine hour meter, ammeter, electric starter
  • Automatic engine idler for better fuel economy, automatic engine shutdown protection for low oil pressure
  • Certified to ISO 9002 requirements, CSA approved
  • 3 year warranty on welding components, engine warranted by engine manufacturer
