The Miller Multimatic 215 is made by Miller Electric Mfg. LLC. Miller Electric has worked its way up to be the world’s largest manufacturer of arc welding products. The company has been around for a whole 90 years, hence why they make such good welders, they’ve had plenty of time to work out the kinks. They have many different types and sizes of welders. Some of them are MIG, TIG, Multiprocess, and Submerged Arc, along with many others.

In this article, we will be focusing on the Miller Multimatic 215, exclusively. It is one of their smaller, lightweight options that they make. This is the welder to get if you need something powerful and reliable, but small for portability.

The Miller Multimatic 215 is fairly small, but not tiny. The dimensions are 20.5” x 11.2” x 12.5”. It weighs only 38 lbs., which isn’t too heavy compared to normal for a welder of this size. This is one of the smaller miller welders.

It can be connected to 120 Volts or 240 Volts of input power. 240 Volts of electricity is better because the welder will run smoother and easier and will reach the appropriate heat quicker. The duty cycle will also be improved by a larger Voltage.

The Multimatic can weld up to 3/8” mild steel but doesn’t do well with metals thicker than that. It can also weld easily on stainless steel or aluminum. You can use this welder for multiple types of welding, including Gas Metal Arc Welding (GMAW), Flux-Cored Arc Welding (FCAW), DC Stick welding or DC Tungsten Inert Gas Welding (DC TIG).

The gas needed for some types of welding, like for DC TIG, does not come included with the welder; it must be purchased separately. The TIG kit is also not included, which is needed to do the TIG welding. One of the pieces that does come with it, however, are a couple of contact tips. The size of the contact tip that comes with this welder fits a 0.30 inch wire.

It has an automatic fan to help keep the internal temperature of the welder regulated. You will want your welder to be cool to prevent the risk of a serious accident occurring due to explosion or overheating.

What TIG Kit to Buy

The TIG kit that is recommended by Miller Electric is the TIG Contractor Kit for Multimatic 215. It is specially designed for the Miller Multimatic 215 welder.

It comes with a Weldcraft A-150 TIG torch, a foot control pedal, a flow gauge regulator and the torch accessory kit. The gas hose is 12 feet long.

Buying the TIG kit is important if you plan on doing any TIG welding with the Multimatic welder. TIG welding is usually used for working on aluminum or chrome-moly steel. The electric torch is used with a filler rod. This kit doesn’t come with the gas you’ll need, and neither does the Multimatic welder, so you will have to purchase that as well.

Welder Review

This welder, along with other welders made by Miller Electric, is expensive. For the size of the machine, it costs considerably more than similar welders made by other brands. However, there are loads of people that say it is more than worth it. Miller has an incredible reputation for the creation of great welders that last a long time.

In other words, there is a legitimate reason why they are so expensive. This is a good welder to go with if you want something reliable and relatively small in size.

It is best used for at-home DIY projects, art sculpture or restorations, it’s not necessarily best for taking on the road to job sites and such.

No matter what you decide to use it for, the welds produced by this welder should always come out nice and clean, at least the majority of the time. If they do not, then it’s probably user error. There is such a huge following and awareness of how good Miller welders work.

However, if a problem does come about or you are not happy with the results, this welder comes with a 3-year warranty through Miller Electric. Even if you buy it with another retailer, the customer service at Miller will work with you on solving the existing problem or give you a refund.

Portability is not an issue at all for this welder because of the double handles and lightweight. It is also very easy to set up and start using.

There is an LCD screen on the front of it, which makes it easy to read what you are looking at. And just in case you are worried about the damage being caused to the screen, an extra protective cover for the screen comes with the welder.


Miller Electric makes very good welders, for all types of welding. Some of their products are huge and made for commercial jobs. Other products, like this one, are small and portable for easy, private use. Typically, welders like this are used for hobbies that involve small amounts of welding.

Use this welder to create outstanding metal sculptures or small artwork. Minor repairs can be done with ease as well. Miller welders create quality welds that will hold for a lifetime. As long as you don’t turn the power up too high, in which case you may burn straight through the metal you are welding, your welds should be at least decent even without having much experience.

This can be a good welder to start with when you begin learning how to weld. Although, not everyone thinks it’s a good idea to spend this much on their first welder. If you are just starting out, get a welder that you can mess around with and will be cheap to replace. Once you get more experience and time under your belt, step up to this welder or another Miller welder to help you further learn.
