Miller Millermatic 142 MIG Welder (907838)
If you're looking for a high-quality, lightweight, and affordable Miller 120V MIG welder, look no further than the Millermatic 142. The American-made multi-process Millermatic 142 welder is loaded with features and so easy to set up that you'll be welding in no time — perfect for hobbyists, small fabrication jobs, or those needing a versatile welding machine.
Auto Set Modes:
A breakthrough synergic control that automatically sets your welder to the proper parameters. Auto-Set offers an all-in-one MIG, minus the hassle of finding parameters. Simply set the wire diameter and material thickness, and start welding.
Manual Mode:
It allows you to manually set the machine when welding aluminum, stainless steel, or any time you want to set custom parameters on mild steel. This is great for users who want complete control over their welding process.
Angled All-Aluminum Drive System:
Robust wire drive with Quick Select drive roll and calibrated tension knob creates consistent feeding speed and easy setup for up to 15-foot MIG guns.
Quick Select Drive Roll:
It makes setup quicker by offering three grooves — two for different-sized solid wire and a third for flux core wire. This makes it ideal for switching between MIG and flux core without changing rollers.
120V Input Power:
This dual voltage-compatible Miller welder uses 120V household input power, so no special power source requirements exist. It is flexible enough to be used in any location, whether in your shop, garage, or out in the field.
Smooth-Start:
This technology provides a smooth, spatter-free start. The Millermatic 142 welder is the best entry-level welder in the 120V MIG category! There is no more pop-gun starts or spatter to clean up — just solid welding performance from the start.
Auto Spoolgun Detect:
It automatically detects when a MIG gun or spool gun is connected, eliminating the need for a manual switch. This saves time and simplifies setup for aluminum welding.
Thermal Overload & 'Tip Saver' Short Circuit Protection:
Shuts down the unit and activates the over-temperature light if the airflow is blocked or the duty cycle is exceeded. Tip Saver shuts down output when the tip is shorted, extending tip life and protecting internal components from damage — a feature ensures welding safety and machine longevity.
