Miller and Lincoln are two large brands manufacturing a wide range of welding equipment. We will be comparing the 210MP, a multiprocess machine incorporating MIG, Flux Cored, DC Stick and DC TIG.
Our second unit is the Millermatic 211, a MIG/Flux-Cored welder compatible with both 120V and 240V input voltages.
But which is the best purchase for you??
Breaking it down
In our comparison we will look at both models by their specification and our experience using each model.
We will compare “deal breakers”, these are factors that either make or break a purchase, and how this will affect your applications with each model.
Bigger isn’t always better therefore this provides you a transparent and direct comparison, to find the best fit for you!
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.
This model weighs 40lb/18.14KG, easy to transport between jobs and not a hassle to carry.
This unit weighs 38lb/17.23KG, also transportable and could be classed as lightweight.
Winner: Millermatic 211… Just!
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.
Duty cycle of:
Winner: Millermatic 211. Despite the lower duty cycle at 240V input voltage, the 120V duty cycle is extremely impressive, and larger by a wide margin.
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 as important.
In our comparison we will look at what each machine can weld in one pass, therefore determining whether one unit is unsuitable from their specification.
The 210MP has a maximum output of 210A, which should satisfy the vast majority of welders out there. This means you can weld 3/8-inch-thick steel and stainless materials or 3/16-inch-thick aluminium.
It can also weld thicker material with multiple passes, however for this comparison we will look at a single pass only.
The Miller 211 can join 24 ga.–3/16 in. steel in one pass, as well as 18 ga.–1/8 in. aluminum when using 120V input voltage.
When using 240V Input Voltage, the 211 can weld 24 ga.–3/8 in. steel as well as 18 ga.–3/8 in. aluminium in one pass.
Winner: Millermatic 211.
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.
Using 120V Input Voltage, the 210MP has an output range between 20-140A DC.
When using 240V Input Voltage, the output range becomes 20-220A DC.
Our second model can output between 30-130A on 120V Input Voltage, and 30-230A using 230V.
Winner: Millermatic 211.
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!
A 3 year warranty is offered on all welding machines, and 1 year on accessories such as gas flow regulators, wire and flux.
A simple and straightforward policy, if you want to read more you can find the warranty PDF under “Industrial Limited Warranty” here(https://www.lincolnelectric.com/en-us/support/Pages/warranty.aspx).
Miller boasts the “Best Coverage” in the industry, according to their warranty page(https://www.millerwelds.com/support/warranty). They offer 3 year parts and labour on inverter machines, and 1 year on accessories (reduced to 90 days if used in an industrial setting).
Miller also specify they guarantee to ship all available warranty items to your Miller service distributors hands within 24 hours, neat!
Lincoln 210MP: 0/5 (1 Tie)
Millermatic 211: 4/5 (1 Tie)
Despite the 210MP performing “poorly” in our comparison, the Miller is a great all round machine. One aspect the Lincoln performs great at is the ability to perform multiple welding processes within one machine.
If you want to have more convenience by incorporating all of your processes into one machine, the Lincoln 210MP is the best choice.
If a well rounded MIG welder is on your shopping list, the Millermatic 211 is the best purchase for you!
