  • Includes running gear/cylinder rack.
  • Light industrial products are suitable for the home hobbyist or occasional user. They are designed to be easy to operate, are affordably priced and typically have a 20% duty cycle and rated output of 230 amps or lower.
  • Unit requires single-phase input power.
  • Unit supplies constant voltage weld output.
  • Unit supplies direct current weld output.
  • Auto-Set™ automatically provides the right settings to weld mild steel while infinite voltage control allows the flexibility to manually set your own parameters: Set the wire diameter (.024 or .030" diameter solid steel wire), a blue light shows Auto-Set is activated; Dial in the thickness of what you're welding; Start welding with the exact parameters you need!
  • Angled cast-aluminum drive system with calibrated tension knob creates consistent feeding and easy setup with included 10 ft. (3 m) MIG gun or optional 15 ft. (4.6 m) MIG gun.
  • 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 and activates the over temperature light if airflow is blocked or duty cycle is exceeded. Automatically resets when unit cools.
  • Uses 4" or 8" (102 or 203 mm) spools.
  • Processes: MIG (GMAW) Flux-Cored (FCAW).
  • Comes Complete with: 10 ft. (3 m) M-100 MIG gun and cable assembly (#248282), 10-ft. (3 m) work cable with clamp, 6.5-ft. (2 m) power cord with plug, Quick Select™ drive roll for .024" (0.6 mm) or .030/.035" (0.8/0.9 mm) solid wire, and .030/.035" (0.8/0.9 mm) flux-cored wire, Flow gauge regulator and gas hose for argon or AR/CO2 mix, two .030" contact tips, Hobart® spool of .030" solid wire, hook-and-loop cord wraps, and material thickness gauge (#229895).
