Northern Industrial Welders MIG 140I Wire-Feed MIG Welder — Spoolgun-Ready, 140 Amp Output

Easy to Use — Ready for Action

Ready to Use Right Out of the Box

This complete welding package is ready for you to dive right into the flux core welding process. And a regulator with gas hose are also supplied for MIG welding. Just hook up your bottle of shielding gas and you are in business.

The Ultimate in Voltage Control

Avoid the hassles of constantly adjusting voltage. The 4-position voltage control includes ranges that allow for automatic handsfree voltage adjustments by the machine while you control the wire feed speed. Infinite voltage control also allows you to fine tune the voltage independently of the wire feed speed for the ultimate in welding performance.

Handy Onboard Settings Guidance

A quick setup guide is located right on the door of the welder, offering easy reference to the preferred settings and other tips you'll appreciate to help you get your project started on the right foot.

Spoolgun-Ready Design

Now you can add a spoolgun to a 115V machine – without the need for any additional equipment! The MIG140i accepts the optional Northern Industrial Welders add-on spoolgun (Item #22224, sold separately) designed specifically for welding aluminum. No more messy and frustrating aluminum projects.

Tough, Capable and Versatile

Ready to Handle the Tough Projects

When it comes to serious work, this welder has some serious capabilities, welding up to 3/16-in. steel in a single pass! Need to weld even thicker materials? You can take care of that, too, by using multiple passes.

Delivers Process Flexibility

Built-in polarity control allows you to set the stage for working in the shop or out in the field. Adjust the polarity control for good, clean welds using MIG welding with a shielding gas. When you're work takes you out and about, the polarity control offers the flexibility to set up for flux core welding almost anywhere.

On-the-Spot Control

When your project requires multiple spot welds where consistent welding is essential, the MIG 140i delivers with an adjustable spot timer for precise welding control. This spot timer offers the consistency you need, helping you avoid costly scrap and timely reworks.

Works with a Variety of Materials

A wirefeed welder that can only handle one kind of metal can really limit your capabilities. That's why you'll appreciate the versatility of the MIG 140i – it allows you to weld steel, stainless steel and even aluminum with ease.

Safety Matters

No More Overheating

Whether you're welding on a hot day or trying to complete an extensive welding project, the thermal overload protection ensures that your welder will stay safe no matter how hard you run it. A built-in thermostat prevents the unit from overheating, delaying welding power until the unit has sufficiently cooled.

Arc Control at Your Fingertips

From seasoned pro to newcomer on the welding scene, you’ll appreciate the safety and security of a trigger activated arc. No need to worry about an accidental arc flash — when you are ready to weld, simply pull the torch trigger and get started.
