A breakthrough control that automatically sets your welder to the proper  parametersAuto-Set offers all-in-one MIG minus the hassle of finding parametersSimply 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 household input power so there is no special power requirementsFlexible to use in any location! 



This technology provides a smooth, spatter-free startThe best starting machine in the 120V MIG categoryNo 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 exceededTip 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. 


Quick Select™ Drive Roll 

Makes setup quicker by offering three grooves - two for different size solid wire and a third for flux-cored wire. 


Generator Compatible 

The Millermatic 141 will be able to operate and provide full output when powered by generators with 4500 Watt (4.5K) output or higher, such as a Miller Blue Star 185 (6200 watts) or Fusion 160 (6200 watts) generator. Limited output will occur when used with smaller generators.
