When put side by side, it can be seen that the Millermatic 211 is a lighter but more powerful machine as compared to the 141, when it comes to voltage input, speed range of wire feed, amperage range, and weld thickness. As it is a more advanced model compared to the Millermatic 141, it features a number of better specs.

Usability

For the Millermatic 141, the highly incredible feature that results in great ease of use is its auto-set control that welders in the 140 Amp class do not have. As soon as the auto-set control is activated, the blue light on the front panel turns on. After that, you simply have to choose the measurement of the wire and the material thickness right on the front of the welder. Now, you are all ready to start your welding project. This is a great way to save up on your time. This is even better for beginners who face difficulty in setting up the welder. With the Millermatic 141’s auto-set control feature, you do not need to go for manual setups anymore, which is really comfortable.

However, if you like to put in some physical effort in your welding tasks, you can decide to go for manual settings as well. With the Millermatic 141, the welder can weld both steel and stainless steel ranging from 24 gauge to 3/16 inch. For aluminum, this range is from 14 gauge to 18 gauge.  It is slightly less powerful than some of the other inverter-based 140A welders since only flux core wire will give you the ability to reach a full 3/16 inch of penetration.

As for the Millermatic 211, the powerful feature is available in this machine as well. On the front side of the machine, you will find a couple of simple options that make setting it up a breeze. It gets you to welding in no time. First of all, the diameter is selected for the wire that ranges from 0.24″, 0.30″ and 0.35″. Once you select the diameter of the wire, a blue LED comes on by the right corner of the panel to indicate that Auto-set is in place.  Then you choose the process type which has a total of five core actions. They include Flux-cored, MIG stainless steel, and MIG steel C25; which is for 25% carbon shielding gas, along with MIG steel C100 which is for 100% carbon shielding gas or MIG aluminum.

last but not least, the metal thickness is selected. Once you have completed your input, the auto-set feature works perfectly to do the welding job. As a user, it is nearly the most perfect user experience that you can get, along with the performance of the arc. The setup is much easier as well as faster compared to other machines on the market.  It is simple to open and assemble. The wire drive system is well designed using cast aluminum and is slightly raised at an angle. It comes with a drive roll which has three grooves to make the wire change possible with the least effort.

Power

The Millermatic 141 features an amperage range from 30A to 140A. The duty cycle for Millermatic 141 stands at 20% at 90A, and 100% at 40A. This means that the welding time at 90A is two minutes and the cooling downtime is 8 minutes long. The machine comes with a prevention mechanism that will make sure that you do not exceed the welding time.

The Millermatic 141 utilizes a 120V power supply, which means that it goes perfectly with the standard residential voltage supply. However, you should know that it is not going to work with generators.

With regards to the 211, it is a dual voltage machine which means that it can be used for both residential 120 V as well as 240V power input. This makes it suitable for all kinds of environments. This means that you can use it indoors as well as outdoors and with the generators as well. This makes it beneficial if you weld in different environments.

It is designed in a way that makes it really easy to switch between the two modes. You just simply need to plug it in, and the machine understands automatically what input you are using. No extra tools are needed to do the replacing and it can be done within seconds.  The weld for a 120V can be around 24ga – 3/16″ steel, and 18ga – 1/8″ for aluminum in during a single pass. The duty cycle is pretty decent; 20% @115A. At 240V input, the weld can be expected around 24ga – 3/8″ for steel and 18ga – 3/8″ for aluminum. The duty cycle is decent here as well, which is 40% @150A. It also has a user-controlled power cooling system which either the user turns on or it turns on itself when the welder needs to be cooled. This is present for the reduction of waste energy as well as noise reduction.

Features

The Millermatic 141 incorporates a number of advanced features. If you are going to deal with mild steel, the Millermatic 141 comes with pre-set mild steel settings. The drive roll is really easy to switch between wire thicknesses and types as well due to its ‘quick select’ system and other pre-set functions.

Furthermore, it has auto-spool gun detection, which eliminates the requirement of a switch. It can be easily used with a 10ft. spool gun. The Millermatic 141 features a smooth arc start at the beginning that is spatter-free, which helps to make cleaner welds. Another good thing about the Millermatic 141 is the entryway outline that allows manual settings. Due to its 120V control, you can easily use it for household welding jobs.

There are just too many good things to name in this post. Better check out the details yourself:
