Overview of Features

Smooth Start: Millers smooth start technology ensures the welder can be started without producing splatter, creating a stable arc ready for use instantly.

Lightweight and Portable: Weighing an impressive 38lbs unboxed (17.24 kg), this unit is easily portable compared to similar models on the market. It measures 11.25 Inches in width, 12.5 Inches in height and 20.5 inches in length, ideal if needing to move between workplaces or storing. Thanks to inverter technology it makes this unit more compact and lightweight, whilst also being able to use a 10lb spool. In addition to this, there’s a handle on top or at the front and back for easy transportation.

Dual Voltage Inputs: Supporting 110/115/120 V as well as 220/230/240 V inputs, you can use this machine on a commercial site or on a home power input. In order to switch between the two different voltage types, all you need to do is rotate the ring on the back of the plug and remove it. Then replace with the other supplied plug. When using 120V you can weld 24ga – 3/16″ steel and 18ga – 1/8″ aluminum in a single pass, with a duty cycle of 20% @ 115A. Alternatively at 240V input power you can weld 24ga – 3/8″ steel and 18ga – 3/8″ aluminum. The duty cycle is 40% @ 150A output.

Fan on Demand: The cooling system is on demand – which means it operates when the unit needs to be cooled. This reduces noise, energy consumption as well as airborne contaminants drawn through the machine.

Millermatic 211 Settings Chart: A detailed settings chart can be found on the inside of the door,

Autoset: Instead of having to manually set the voltage and feed speed, then having to test these settings on scrap material you can use the autoset feature to remove the guesswork. To use you need to select the wire diameter you plan to use (0.24″, 0.30″ and 0.35″), as well as the material thickness. You’ll see on the front of the control panel a blue autoset light will illuminate, which requires you to select the process type – Flux-cored, MIG Stainless Steel, MIG Steel C25 (25% carbon shielding gas), MIG Steel C100 (100% carbon shielding gas) or MIG Aluminum. Finally you need to select the material thickness, and the autoset feature will setup the parameters for you perfectly.

Inverter: There are two types of welders on the market, inverter and transformer. Due to advances in technology the vast majority of units on the market make use of inverters due to their increased energy efficiency, arc performance, arc stability and portability.

Quick Select Drive Roll: Featuring three grooves with one suitable for flux-cored, and two grooves for different sized solid wire. This makes switching wire types simple and easy, and can be completed in a matter of seconds.

Auto Spool/Gun Detect: When connecting a gun to this welder, it will automatically detect if it’s a MIG or Spool Gun and adjust accordingly. Reducing the need for user input, and remembering another setting to change.

Thermal Cut Out: When the machine reaches it’s maximum operating temperature, it will cut the arc and prevent you from continuing to weld. This is an automatic feature to protect the unit, and prolong it’s operating life.


Will this welder suit my needs?

The features and specification of this model are well suited towards DIY/Home Hobbyists, Farm work or beginner commercial work. The output and features of this welder ensure you can weld with a variety of metals and thicknesses, as well as the units portability and compact design mean it’s easy to move between jobs or store when not in use.

For a setting which requires high workload, this unit may not be the best solution due to the lower power output and duty cycle. A water cooled unit which can sustain higher output amperage for longer periods of time would be a better solution.

Can This Weld Stainless Steel?

Yes this welder can weld stainless steel. It’s important to use the correct shielding gas mixture and wire to ensure quality welds.

What Size Breaker Should I use?

A 30A breaker using 10 gauge wire will run this welder with no problems, as its rated amp draw @ 220V 150A output is 24.3A. This is a guideline and you should consult a qualified electrician to be completely certain your wiring is safe.
