Miller 141 Vs 211

How are these two welders similar?

Process Type: The basic process goes through for both Millermatic 141 and 211 MIG welders using MIG or metal inert gas and flux-cored welding. You can weld steel, stainless steel, and iron by this method with these machines. And with the help of a Spool gun, you can weld Aluminum as well.

Auto Spool gun detect system automatically detects when a MIG gun or spool gun is connected. So, you don’t have to worry about switching systems manually.

Smooth Start Technology: Both the machines come with smooth start technology. This technology allows a smooth and spatter-free start than other welders in the market. This eliminates the mess to clean and no more pop-gun starts. The blue LED light indicates the auto-set activation.

Quick Select Drive Roll: The set-up time for these two machines is roughly half an hour. After selecting the wire type (solid wire/flux-cored wire), you just need to put it on the proper grooves. The machine includes a roll with three different groves.

What are the key differences between these two welders?

Inverter Technology: Even though Miller 141 and 211 have similar features, Millermatic 211 serves a much wider range of wire feed speed because of its built-in inverter technology. For 211, the speed extends from 60 IPM in 1.5m/min to 600 IPM in 15.2 m/min while for 141; it differs from 15 IPM- 360 IPM (0.4-9.1)m/min.

This technology also allows the machine to weigh only 38-pounds and Miller 141 weighs almost 65-pounds. Therefore, in terms of portability and travel speed, Miller 211 serves the best.

Fan-On-Demand: This system activates only when it is needed. And that helps to reduce noise and energy uses and controls the amount of contaminants that the machine pulls insides. Not to mention, this is an exclusive feature for Miller 211.

Input Power: Miller 211 operates on a dual 120 and 240V which provides 40% of duty cycle at 150 Amps. Whereas Miller 141 operates on a single 120V provides 20% duty cycle at 90 Amps.

You can weld for 2 minutes straight and then cool down for 8 minutes.

Material thickness: The Metal thickness to be weld is diverse for 211 than 141. Using Miller 211 you can weld

  • Mild Steel 24 ga. -3/8 in.
  • Aluminum 18 ga. -3/8 in. 

And using Miller 141 it changes as follows:

  • Mild Steel 24 ga (0.8 mm) – 3/16 in. (4.8 mm)
  • Aluminum 18ga (1.2 mm) -14 ga (1.9 mm).
