  • Portable wire feeding at its best, the improved 12VS provides wire feed speed accuracy that rivals the best benchtop feeders.
  • Polypropylene case with built-in slide rails has door for changing wire with the feeder in a vertical position.
  • Potted and trayed main printed circuit board for the harshest environments adds exceptional reliability. Board has full-trigger isolation so a shorted gun trigger will not affect feeder operation.
  • Improved contactor for high-amperage, high-duty-cycle applications.
  • Digital meters with SunVision™ technology can display voltage, wire feed speed, and also amperage if desired. Meters can be seen clearly even in direct sunlight.
  • Wider voltage range for small and large wires with no contactor chatter or arc outages.
  • Double-filtered gas valve helps keep dirt from clogging and affecting gas flow.
  • Excellent starts and superior arc performance for all types and sizes of wires whether using CV or CC power supply. (CV is recommended for best arc performance.)
