  • 10-ft. (3 m) work cable with clamp
  • 6.5-ft. (2 m) power cord with plug
  • Argon and AR/CO2 mix flow gauge regulator with gas hose
  • Hobart® spool of .030-in. (0.8 mm) solid wire
  • Two contact tips for .030-in. (0.8 mm) wire
  • Quick Select drive rolls for .024-in (0.6 mm) or .030/.035-in. (0.8/0.9 mm) solid wire, and .030/.035-in. (0.8/0.9 mm) flux-cored wire
  • Material thickness gauge (#229 895)

Auto-Set™
A breakthrough control that automatically sets your welder to the proper  parameters.  Auto-Set offers all-in-one MIG minus the hassle of finding parameters.  Simply set the wire diameter, set the material thickness, and start welding!
Segmented Display
Easy to read display gives you the flexibility to set the machine precisely and accurately in Manual and Auto-Set modes.
120V Input Power
Uses 120V input power so there is no special power requirements.  Flexible to use in any location!
Smooth-Start™
This technology provides a smooth, spatter-free start. No more pop-gun starts or spatter to clean up.
Thermal Overload & 'Tip Saver' Short Circuit Protection
Shuts down the unit and activates the over-temperature light if the airflow is blocked or duty cycle is exceeded.  Tip Saver shuts down output when the tip is shorted to the work extending tip life and protecting internal components from damage.
Auto Spool Gun Detect™
Automatically detects when a MIG gun or spool gun is connected eliminating the need for a switch.
Generator Compatible
The Millermatic 142 will be able to operate and provide full output when powered by generators with 5,000-watt (5.0K) output or higher, such as a Miller Blue Star 185 (6200 watts) or Fusion 185 (6200 watts) engine-driven welder. Limited output will occur when used with smaller generators.
Quick Select™ Drive Roll
Makes setup quicker by offering three grooves - two for different size solid wire and a third for flux-cored wire.

Not Included

  • Shielding gas for welding with solid wire (GMAW)
  • Spool Gun for welding aluminum
  • Small running gear/cylinder rack
