The Miller brand has an impressive catalogue of welding machines under its name. Started in 1929, Miller Electric is one of the most experienced welding machines manufacturers. And you can never go wrong with a Miller welding machine.
Miller welding machines are some of the best on the market. However, they are also some of the priciest. With some costing as much as $5,000. At such hefty price tags are they worth it? In this article, we are going to be comparing two of the company’s pricey machines.
These are miller 211 vs 215. The latter is the pricier of the two and has most to offer. The 215 is a multi-process welder while the 211 is a MIG welder. So are they worth their hefty price tags?

Miller 211 vs 215 :other considerations on which to choose
As mentioned above, the Miller 215 is the costlier of the two and for good reasons. It is capable of performing Mig; flux cored Mig, stick and TIG welding. On the other hand, the 211 is a MIG welder with advanced features.
In regards to size, height to be more specific, the two are equal. Both measure 12.5 inches in height. Thus are both compact and will not require a lot of storage space.
As with the height, the two also share the same length. They both measure 20.5 inches long. As such, they are not as big as some of their competitors.
In regards to dimensions, these two machines are virtually of the same size. They both measure 11.25 inches in width. Thus while the miller mig 211 does come with a cart, their overall dimensions are the same.
One of the most important factors to consider when purchasing a welding machine is the duty cycle. This is one area where these two machines differ. The miller 211 has a duty cycle of 40% at 150 amps.
The miller multimatic 215 duty cycle, on the other hand, is not standard. Due to the machine being capable of different welding processes. For MIG flux-cored welding it offers a duty cycle of 20% at 200 amps and a 60% duty cycle at 110 amps.
For TIG welding, you get a duty cycle of 20% at 190 amps and 40% at 140 amps. For stick welding, the duty cycle is 20% at 190 amps and 40% at 90 amps. It is not fair to compare the duty cycle of these two machines due to how different they are.
For MIG welding, however, the miller 211 is the better option. This is especially since it costs less and can weld both steel and aluminum sheets.
When you are spending thousands of dollars on a machine, you will want it to be compatible with both your home’s 120v socket as well as a high power 220v socket. Thankfully, both machines have a dual voltage plug.
Thus, you can plug them into 110v, 115, and 120v power receptacles. For more heavy-duty welding you can plug them into either a 220,230 or 240 v socket.
The miller 211 is a MIG welding machine. It can perform both flux-cored mig and non-flux cored MIG welding. The miller 215 multimatic on its part is a multi-process welding machine. It can be used for MIG, Stick and TIG welding applications.
As such, as part of the package, you get a miller 215 tig kit. As with the 211, the 215 can perform both flux-cored and solid wire MIG welding. This is one of the reasons why the 215 is the costlier of the two.
It removes the need for owning three different welding machines. And gives you the freedom to perform a wide array of welding applications. Also, since it is capable of stick welding, it can easily be used outside in windy and rainy conditions.
One area where both machines excel is in the weight department. As discussed above both machines are pretty compact. In addition to this, they are also relatively lightweight. Both weigh 38pounds.
Thus they are portable. The 211 is slightly more portable though as it comes with a cart included. The wheeled cart makes it easy to transport. And when you consider it’s the cheaper of the two, it’s easy to see why I rank it as the more portable of the two.
Nonetheless, the pricier 215 multimatic can be carried with relative ease. It features a handle that makes it easy to carry.
How well do these two do on metals of varying thickness? The Miller 211 can weld metals of up to 3/8 inches in thickness. It can also handle thinner metals of up to 24 gauge in thickness. For the Miller 215, it depends on the welding process.
For MIG welding you can weld steel sheets of between 24 gauge and 3/8 inches thick. On the other hand, you can weld aluminum sheets of between 16 gauge and 3/8 inches thick. When it comes to TIG welding, you can weld metals of between 24 gauge and ¼ inches thick.
With stick welding, you can weld metal of between 16 gauge and 3/8 inches in thickness.
Wire feed speed range
The drive rolls on both machines are designed to offer you hassle-free, reliable and smooth wire feed. When it comes to the wire feed speed, the 215 multimatic has a wire feed speed range of 60 to 600 ipm. Similar to the 215 the miller 211 also has a wire feed speed range of 60 to 600 ipm or 1.5m/min to 15.2m/min.
Welding Amperage Range
The welding amperage range of these two machines differs. The miller 215 has an amperage range of 20 to 230 amps. On the other hand, the miller 211 has an amperage range of 30 to 230 amps.
One of the best things about these two Miller welding machines is that they can weld almost all types of metals. The two can weld both ferrous and non-ferrous metals. Thus, you can weld mild steel as well as aluminum.
One of the main differences between these two machines is in the polarity they use. The Miller 211 can weld with both DC and AC. However, the Miller 215 is a DC only machine. And it is for this reason that it is not suited to welding aluminum.
Value for money
When it comes to value for money, the Miller 215 is the better of the two. It does the work of three machines. Thus, with it you do not have to buy an additional machines. With the Miller 211 you may have to buy another machine for stick and TIG welding.
Which one is best for what?
Both are excellent machines that offer value for your money. However, each has its own unique strong points. While the 215 is ideal for multipurpose work the 211 is ideal for MIG welding. The less costly Miller 211 is ideal for MIG welders.
Thus if you need a welding machine for fabrication works the Miller 211 is best. It can weld both ferrous and non-ferrous metals. Also, it can weld metals of varying thicknesses from 24 gauge to ⅜ inch thick.
However, if you are looking to splash money on a high quality machine that does the work of three machines go for the 215. The latter can perform TIG, stick and MIG welding. This makes it ideal for professionals who engage in different kinds of welding applications.
The Miller 211 will also appeal more to people who do alot of aluminum welding. The 215 is not capable of TIG aluminum welding.
Which is the best?
The Miller 211 comes with an impressive set of features. The auto-set feature in particular. As already stated its a dual voltage welder. As such, you can plug it to a standard 120V power receptacle as well as a to a 240V one.
As for its advanced auto-set feature you do not have to guess the right voltage settings. Just choose the material thickness and wire diameter and the machine will do the rest. Compared to other Miller welders this is quite lightweight. It weighs 38 pounds, which is significantly lighter than most similar products.
The Miller 215 on the other hand offers almost the same features you get from the 211. However, it has one big advantage over its counterpart. Unlike the 211, the Millermatic 215 can handle stick, MIG and TIG welding.
The only complaint about the 215 is that it is not suited to aluminum TIG welding. But for other materials it performs excellently. This gives it an edge over the Miller 211.
So which is the better of the two? When you compare the miller 211 vs 215, it is clear that the 215 has more to offer. Hence why it is the pricier of the two. However, if you are looking for a good welding machine for MIG welding, the 211 will be ideal.
The 215 offers everything that the 211 offers with some added features. It is worth the investment as it combines the capabilities of three different welding machines.
