This welder is appropriate for both professionals and hobbyists and is well known for its ability to produce neat welds without spatter. When it comes to usability, the Miller Millermatic 141 is in a class of its own, particularly due to its minimalistic design.

Weighing an impressive 51lbs, this welder is highly mobile and can be carried around. Its compact design also helps it to fit into your car or work truck without occupying much space. With an input voltage of 120V, you can use this highly capable machine around your garage or at home without having to worry about voltage restrictions.

Before examining the features of the Miller Millermatic 141, let`s take a quick look at its performance based on usability, power, price and portability.

The Miller Millermatic 141 in a Nutshell


Although the Miller Millermatic 141 does not rank up as one of the most powerful welders, it has some state-of-the art features that make it a superior welder to have in your garage or workshop. This bad boy comes with an auto-set control feature which helps reduce the effort required when setting up to weld.

A blue light appears when you activate auto-set. Once the blue light appears, your work is to select the material thickness and wire diameter and then proceed to weld. This feature is convenient for professionals looking to save time and first timers with little experience in welding.

You can also choose to set the machine manually if you prefer taking a hands-on approach. Just check the usage chart on the inside of the welder`s door and select the controls from the available options. It comes with 10 wired feed speed settings and an infinite voltage control as well. The Miller Millermatic 141 can weld stainless steel and 14-18 gauge aluminum.


The Millermatic 141 boasts of a duty cycle of 20% at 90A, meaning you will have to give the welder an 8 minute break if you weld for 2 minutes. At 40A, the duty cycle stands at 100%. This modern welder has an amperage range of 30A to 140 A, which allows you to perform a variety of welding tasks in your garage.

The infinite voltage control settings give you maximum control and help improve your welding outcomes. And since the Millermatic 141 runs on a 120V outlet, it shouldn’t be too hard to find a compatible outlet within your home or garage.

Price and Warranty

Expect to get a 3 year Millers True Blue warranty once you purchase this product. Of course, due to its tech upgrades and additional features, the Miller Millermatic 141 costs more than the handler 140.

The voltage control and auto set features contribute to the slightly expensive cost of this welder. However, the price is totally worth it if you consider the neat welds it produces as well as its superior performance.
