Miller are a well-known and respected brand in the Welding space. In our comparison we will be looking at the Millermatic 211, and the Multimatic 215 which is miller’s Multi-process welder range.

The Millermatic 211 is a mid range MIG welder, compatible with 110V and 220V input voltages, with many goodies from Miller such as their advanced Auto-Set feature and Smooth Start technology making welding much easier.

The second model we will be looking at is the Multimatic 215, a great Multiprocess welder capable of MIG (GMAW), Flux-Cored (FCAW), Stick (SMAW) and TIG DC (GTAW). Also compatible with 110V and 220V input voltages. What’s great about the Multiprocess range is incorporating multiple welding processes within one unit.

Breaking it down

In our comparison we will compare both models by their specification and experience using each model.

As one unit incorporates multiple processes we will focus mainly on MIG, however when making the final decision it’s important to factor this into the final decision.

We will be comparing each main aspect of these welders to give you an idea what to expect, in terms of performance from each machine.

Bigger isn’t always better therefore this provides you a transparent and direct comparison, to find the best fit for you!

 

Weight

As inverter welders are significantly lighter than their transformer counterparts, more operators are becoming interested in the weight of their machinery. Portability of equipment has become more important to buyers, as one machine has the potential to fulfil all of a welders desired applications.

A products weight will depend on many factors such as build quality, output amperage, features and size. Depending on what you want from a machine, a heavier therefore less portable machine isn’t necessarily a bad choice. Some machines can weigh less than 10lb, however their capability will be less than a heavier machine.

 

Millermatic 211

This unit weighs 38lb/17.2KG, making it light enough to carry whilst maintaining build quality.

Multimatic 215

This model weighs the same at 38lb/17.2KG, also light enough to transport and carry comfortably.

 

Winner: Tie!

 

Duty Cycle

Duty Cycle is the amount of time as a percentage, that a welder can produce the stated output (typically referencing a total period of 10 minutes). For example a 20% Duty Cycle @ 90A means 90A continuous output for 2 minutes, with 8 minutes cooling off.

The working section of the duty cycle will be lower, the closer to the maximum output amperage of the welder.

Duty Cycle is a good metric for comparison because a short duty cycle affects productivity, therefore giving you less arc time the more you demand from your equipment.

 

Millermatic 211

Has a duty cycle of 40% @ 150A on 220V input voltage, and 20% @ 115A on 110V input voltage.

 

Multimatic 215

The Multimatic has a 40% Duty Cycle at 150A (220V Input voltage), and 20% @ 115A using 110V (20A) input voltage.

 

Winner: Tie!

 

Material Thickness

The range of thickness a material can join in one pass is a key point in buying a welder. There’s no point purchasing a welder that can’t join material you want to work with!

The lowest thickness is also important to note too. Although the upper limit of material thickness is important, being able to weld thinner sheets such as auto body panels without blowing holes though the material is also important.

In our comparison we will look at what each machine can weld in one pass, and whether one unit is unsuitable from their specification.

 

Millermatic 211

The handler 140 has a lower limit of 24 ga, and an upper limit of 3/8” Inch when working with steel. When welding Aluminum you can join material between 18 ga. – 3/8” thick.

It can also weld thicker material with multiple passes, however for this comparison we will look at a single pass only.

 

Multimatic 215

Our Multimatic model can weld a variety of material, as it incorporates multiple processes into one machine.

 

MIG: 24 ga. – 3/8” Steel

18 ga. 3/8” Aluminum

 

TIG: 24 ga. – ¼” Steel

Stick: 16 ga. – 3/8” Steel

 

Winner: Multimatic, due to it’s ability to work with more material as it’s a multiprocess model.

 

Output Amperage Range

Output Amperage and Material Thickness go hand in hand, as more amperage allows you to weld a thicker piece of material.

The slight difference comes with the types of material you want to work with, for example steel will require a slightly higher amperage compared to aluminium despite both pieces of material being the same thickness.

By comparing the amperage range, you can see which machine is more suitable to your desired work material.

 

Millermatic 211

The Millermatic can output between 30-230A on 220V, and between 30-130A using 110V input voltage.

 

Multimatic 215

Depending on the welding process used, the 215 can weld:

 

MIG/Flux-Cored: 30-230A

TIG: 20-210A

Stick: 30-200A

 

Winner: Miller Multimatic 215

 

 

Warranty

A brand confident in their products quality will have a long warranty, giving you confidence that it will be repaired if the worst happens.

Especially if you rely on your welding equipment to generate income, you don’t want to worry about your equipment’s ability to perform properly for the long term. Sometimes the cheaper option can become the most expensive!

Most equipment is covered by at least a years manufacturers warranty, assuming the equipment hasn’t suffered water damage and has been serviced by an approved service center.

 

Millermatic 211/Multimatic 215

Miller offers a 3 year parts and labour on the welder itself, providing it’s serviced by a Miller authorised service centre.

 

The peripherals such as torches/guns have a standard 1 year warranty, reduced to 90 days if used in an industrial application. Generally they don’t include labour in their peripheral warranty, however their warranty information can be found here for clarification.

Welding Processes

The capability of a machine will dictate what you can do with it. Everyone’s requirements differ slightly, therefore finding the perfect purchase for you is essential.

A machine that can’t keep up with your requirements isn’t a good purchase, so let’s see what each machine can do – and what this means for you!

 

Millermatic 211

Capable of MIG and Flux-Cored welding processes only. A well rounded machine and a perfect purchase if you only wish to MIG weld.

 

Multimatic 215

Capable of MIG, Flux-Cored, DC TIG and Stick. Although this model has a wider range of processes, it’s important to note:

 

  • Requires a TIG torch and associated equipment (bundled from factory by Miller) in order to TIG weld.
  • Cannot TIG Aluminum, as this requires AC TIG.

 

Winner: Miller Multimatic 215
