Flux Cored (FCAW)
Garages/ Body Shops
Farm and Ranch
is a breakthrough control that automatically sets your welder to the proper parameters. Auto-Set makes set up very simple and gives you precise settings instantly. Manual Mode allows you to manually set weld parameters for broader applications.
Infinite voltage control
replaces "tap" settings which means you can now "dial in" precise weld voltage and wirefeed speed when using the Manual Mode.
Compatible with Spoolmate 200 spool gun!
The Spoolmate 200 with wire feed speed control on the gun saves time for the operator by eliminating the need to go back to the machine to change the spool gun wirefeed speed.
Line Voltage Compensation
keeps welding output constant even if power input varies by +/- 10%.
No more replacing mechanical output contactors.
Our built-in solid-state contactor circuit makes wire electrically "cold" until the trigger is pulled, and gives you life-long welding output and performance.
Reduce Maintenance and Operating Costs with our Fan-On-Demand™
cooling system that only operates when needed, reducing power consumption and contaminants drawn into the machine.
EZ-Access™ Consumable Compartment and Parameter Chart -
convenient new flip-down compartment that provides fast access to parameter chart and consumables.
Larger work area -
now with longer 15-ft M-25 gun.
EZ-Change™ Low Cylinder Rack
allows operators to easily roll cylinders on and off of rack - no need to lift cylinders.
Compatible with Bobcat™ welder/generators.

Great machine, great price, fast delivery.
December 22, 2016
I love it. We rarely deal with anything over 1/4", but I prefer to have a machine that has a greater capacity than I need.
Miller welders are the best. I have purchased 3 migs, and 2 tigs in the past 26 years for my restoration shop. The migs have rolled many miles of wire without any problems ever. I only replace them for insurance sake, and keep 2 at all times. Cyberweld has the best prices, and fast, free delivery can't be beat. I just bought my new Miller 212 this month (Dec. 2016)

Extremely pleased. The welder works great and exceeds all my expectations! Whether I'm welding thick steel plate or installing patch panels on another classic truck project, my Miller 212 steps up to task without hesitation! Once again, Miller has met and exceeded my expectations!
The ability to switch between auto-set and manual mode makes for greater versatility. The run-in setting is really nice once I had it set to my preferences. It comes set as 50% from the factory.
I didn't buy it sooner!
really good product

It is absolutely everything Miller says it is. Well worth the price. Cyberweld delivered on price and on time and was very prompt with rebate paperwork. Will definitely use them again.
Wish it had a better way of storing cables like some of the older Millermatics.
Great mig welder

Great machine - makes me weld like a pro
September 2, 2015
My miller 212 is the perfect set for a hobbiest and arrived on a pallet, set up was easy 20 min from box to welding.
Easy set up and use
220 line could be longer, all lines would be more convenient if 3 or 4 ft longer
Great product but terrible shipping.
August 13, 2015
Item exactly as described. Emailed for an eta on shipping and gave my zip code. Was told it would take about 3 days being I was in Texas and it shipped from in state. Took over two weeks due to first carrier subbing it out to another carrier. Be careful if you are in a hurry. This aside, good product, great price, and customer service that responds quickly.
Price, free shipping

Love this machine!
March 13, 2015
I burned a few miles of wire using commercial MIG machines in a farm equipment plant while in college. Having that experience, I wasn't expecting much from the little Millermatic 212. That turned out to be wrong. I found this machine to be easy to set up, and a dream to use. The commercial equipment I was familiar with were strictly manual adjustment machines so, again, I was skeptical of this Auto-Set business. That also turned out to be wrong. I was pleased to discover how well the Auto-Set feature works. Dialing in the wire dimension and base metal thickness is giving me close to perfect welds with only minor tweaking, if any.The only thing I found irritating about this machine was the Mickey Mouse method Miller provides for accommodating small wire spools. I set this machine up on Sunday and I all had was a 2 lb. spool. Unfortunately, I could not find a local source of 10 or 11 pound spools. Miller's solution is to remove most of the spool hub parts and replace them with a 2" piece of PVC. I didn't have the right diameter PVC so had to beg a piece from my neighbor, which fit the 2# spool but was a loose fit on the spindle. It worked, but reminds me of using knock-off parts on a BMW. Miller might want to consider at least providing the dimensionally correct PVC with the machine. This is admittedly a minor whine, but it just seemed cheesy to me. Oh, I should point out that CyberWeld did a great job getting the machine to me on time and in one piece.
This is an Awesome machine.
March 5, 2015
I was given this welder for my birthday 2 years ago. I have used the hell out of it, and it has performed flawlessly.
Easy set controls, easy set up, and the aluminum spool gun operates very well on this unit.
I wish all welders came with a better way to store the ground and feed cord.
Cant go wrong
August 15, 2014
Great price, great unit, can not ask for much more!
Very Happy with my welder
July 3, 2014
have had this welder for about 2 yrs. now, still feel that it was a good investment. Had a little trouble with a circuit about 3 months after i got it,but had it repaired and no trouble since. Also purchased the 140/120volt model,and it does a great job too.
One of the best welders today
March 26, 2014
Used it yesterday for the first time. I am very happy with the product. Duty cycle was important to me and this machine is doing the job for me.
November 15, 2013
Very satisfied with this item.
June 15, 2013
I purchased this machine to do repairs on my construction equipment and trailers it has more than paid for its self, I don't have any formal training but it made welding easy and affordable, I built a attachment for my Bobcat and I welded for 2 hours on it highest setting and it never hit the thermal overload and got the job done. I used the attachment to demo concrete slab and had a piece 5'X7' 4" thick and looked at all welds no problems, great machine would tell any one to buy Miller.
very simple to use the Auto-Set and weld
cant think of any
February 1, 2013
This review deals mainly with the Cyberweld buying experience, which I rate a 10 star evaluation. Everything ordered was delivered and packaged well enough to avoid damage. Cyberweld has a lot of merchandise to pick from, the price and shipping are without equal. All in all a great buying experience. I bought the miller212 with the spool gun and it arrived in 5 days dropped shipped from Cal to AZ with no damage. The assembly of the dual cylinder cart was a pita due to crappy instructions and miss identified threads on the fasteners and the heads of the fasteners being 3 different sizes. Gimme a break! Also the ground clamp (made in china) is a real cheapie, but easily replaced with a Twecko copper ground clamp bought from Cyberweld!!! But that is a Miller problem.....Not Cyberweld. Would I buy from Cyberweld again? You betcha.....as a matter of fact I look forward to it!

Owner of the welder.
October 8, 2012
The unit is much more robust that the last unit I owner. The operation is quieter and mobility is excellent. I am much more pleased with this welder.
1) Mobility - bottles and all on one carriage. 2) Ease of operation. 3) Better duty cycle.
Nothing so far.

thank you cyberweld for fast shipping. i got the machine before there delivery date. the only thing now is that i bought the machine about a month ago. i did not used it as soon as it arrive. i left it on the crate for 3 weeks and the day i used it, i notice that the rear wheel did not have the locks. and the wheels kept falling off. then after 30 minutes the spool gun started squirting wire by itself before it quit welding. i turned it off and look it up on the owners manuel i did not find anything on the trouble shooting section so i called miller and they told me to take it to the service center its been a week and they havent fix/replace it. it very frustrating that i spend that kind of money on a welder that i cannot use. the miller service center said it would be another week before they would get to it. if i would of known that miller did not take care of there customers i would of gone a different route.
Fast freindly service from cyber weld
They are trying to fix a lemon machine that clearly should be replace

Great Mig Welder, Takes a little while to get it dialed in.
Always recommend Miller products
July 23, 2012
The MIG is used mostly for assembly of cranks on a volunteer project involving a 3 wheel hand cranked wheelchair for leg handicapped people. (giftofmobility.org) In addition I do general job shop projects such as make antique motorcycle parts. Since some work is delicate, I bought the smaller MIG torch for greater flexibility. I am very pleased with Miller products and always recommend them.

I currently own a Bobcat 250 NT welder, will this have a stable enough power output to run a 212 MIG machine or should I consider a purchasing a 12vs and running it off the welder output? Thanks John
Millermatic 212 MIG Welder Auto-Set 907405 would run of your Bobcat. The 212 is the biggest machine miller recommends running off a Bobcat.

You did not indicate the thickness of the materials you will be welding.. If the material is 3/8" or less the Millermatic 212 MIG Welder Auto-Set 907405 can weld it with one pass.. If the material is thicker than that you may want to consider a Millermatic 252

March 31, 2015
I'm considering the Millermatic 212 vs the Hobart Handler 230. What are the advantages of the Miller and the Hobart?
The Millermatic 212 MIG Welder Auto-Set 907405 and the Hobart Ironman 230 MIG Welder 500536 are comparable .. Hobart has a little more power than the Miller.. The duty cycle on the Hobart is 60% @ 175 amps.. The Miller duty cycle is 60% @ 160 amps. The max output for the Hobart is 250 amps while the Miller is 210 amps.The Hobart has a 12 position tap switch for voltage control.. The voltage control on the Miller is infinitely variable which provides more precise control .. The Miller also has Auto Set which automatically sets the wire feed speed and voltage parameters. The Hobart does not have Auto Set feature The Hobart Mig Gun is 15ft rated at 200amps.. the Miller Mig Gun is also 15ft long but is heavier duty gun rated at 250 amps.Both machines are spool gun ready. The recommended spool gun for the Hobart is the Hobart DP 3545-20 while the recommended Miller spool gun is the heavier duty Spoolmate 200

from Central Washington asked:
January 19, 2015
I'd like to have the flexibility to use the MM 212 remotely, while using my portable generator as the power source. The 212 power cord terminates with a NEMA 6-50 plug and my generator includes a 240v NEMA L14-30 (30amp, twist-lock) outlet. If I [have my qualified electrician] make up a pigtail to adapt from the 212's NEMA 6-50 plug to the generator's NEMA L14-30 outlet, will I be good to go?
You did not indicate the KW rating of your generator. The Millermatic 212 MIG Welder Auto-Set 907405 will require 5.5 kw in order to operate.. On 230 volt the unit will draw 27.1 amps. If your breaker is rated at 30 amps and your generator is capable of approx 6 kw the 212 should run using your pig tail. You are going border line on this set up and may find that you cannot get full output from the 212 without tripping the breaker

from Columbus, Ms asked:
December 6, 2013
I saw in your power accessory section that you have the following extension cords...Direct Wire Extension Cord - 230 Volt , 25' or 50' 8/3 Would these be compatible with the Millermatic 212 Mig Welder throughout its application range? Since my only source of 230 volts is my dryer outlet I would love to be able to use it and not have to pay for additional 230 outlet installation.
Thanks for the info.
The Millermatic 212 MIG Welder Auto-Set 907405 will work properly with the Extension Cords. The only question that needs to answered is what type of receptacle you have on your dryer.. The Extension Cords have a NEMA 6-50 p style plug if your dryer has this type of receptacle then it is a direct plug in.

from Lake Asbury Fl asked:
July 19, 2013
In the information sheet it says the package comes with 15-ft 250-amp M-25 MIG gun for .030/.035-in wire. Does this mean that if you want to run .023 or the .045 you have to buy a new gun, is my in-experience making me miss something?
The Millermatic 212 MIG Welder Auto-Set 907405 comes set to run 030/035 wire .. If you plan on running .023 wire you will need to replace the gun liner (194010) the drive roll set (087131) and the contact tips (087299). The Millermatic 212 would not be a good choice to run .045 wire

Will my spoolmate 100 hook up directly and work OK for this light duty? Thanks... Steve
The Spoolmate 100 spool gun cannot be used with the Millermatic 212 MIG Welder Auto-Set 907405.. The 212 is designed to work with the Spoolmatic 30a /15a or the Spoolmate 200
