Works on single or 3-phase power, and is packaged in a durable, 40 pound aluminum case. Simple to operate with a process selector knob that automatically sets the proper Dig setting for Stick. Can be used alone or rack-mounted in 4-pack racks convenient for construction and shipyards.


  • Inverter-based, DC power source has a SIMPLE-TO-USE OPERATOR INTERFACE providing ony the necessary controls in a compact machine.

  • PROCESS SELECTOR KNOB automatically sets the PROPER DIG setting on E6010 & E7018 and adjusts amperage.

  • Superior Stick arc performance even on difficult-to-run electrodes like E6010.

  • DURABLE & PORTABLE, 40 LB aluminum case is easy to install with 230 V or combination 460/575 V input.

  • Adaptive HOT STARTT for Stick arc starts automatically increases the output amperage at the start of a weld should the start require it. Prevents the electrode from sticking and creating an inclusion.

  • Lift-ArcT start provides TIG arc starting without the use of high frequency.

  • Remote amperage control provided through 14-pin receptacle on front of machine. This permits use of standard amperage control devices.
