Item Details

  • MIG and flux cored 120 V welder that welds from 24 gauge - 3/16 in. mild steel.


  • Auto-Set™ automatically provides predefined weld settings for mild steel and aluminum while infinite voltage control allows the flexibility to manually set your own parameters with a digital readout.
  • Angled cast-aluminum drive system with calibrated tension knob creates consistent feeding and easy setup
  • Quick Select™ drive roll makes setup quicker by offering three grooves -” two for different size solid wire and a third for flux-cored wire
  • Auto Spool Gun Detect™ automatically detects when a MIG gun or spool gun is connected, eliminating the need for a switch
  • Smooth-Start™ provides a smooth, spatter-free start. It's the best-starting machine in the small MIG machine category
  • Thermal overload protection shuts down unit if airflow is blocked or duty cycle is exceeded
  • Automatically resets when unit cools
  • Fan-On-Demand™ cooling system only operates when needed, reducing noise, energy use and the amount of contaminants pulled though the machine
  • Uses 4- or 8-inch (102 or 203 mm) spools and can be set up to weld with .024-.030 inch (0.6-0.8 mm) solid wire and .030 - .035 inch (0.8-0.9 mm) flux-cored wire.
