Miller Multimatic 200 Review - (2024)

Not sure if this is the right place for this thread, but thought it was a good place to start. I've always had a Lincoln Weldpak Mig welder for the weekend'er welding projects I had with light steel. Now that I'm doing a lot more welding I'm looking to upgrade. I would like to learn to Tig weld but also like the ease of Mig welding mild steel. A buddy let me try his Multimatic 200 and I was impressed with how smooth the Mig welding feature was. He did not have a spool gun for aluminum or a Tig torch so I couldn't try those features. Anyone have any experience with a Multimatic 200 and if they really are good for Tig welding Steel and Mig Welding (with spool gun) Aluminum?

90% of what I do is weld 11ga steel that I plasma cut. But every once in awhile I will do an aluminum or stainless project and need to hire a buddy to do the welding. It would be nice to keep those in house. I don't believe I would need to weld Stainless or Aluminum over 1/8".

I thought about buying the multimatic a while back, but ended up with the millermatic 211 instead. I don't have a spool gun for aluminum yet, but will be getting one soon.

I have welded stainless and mild steel with it, did great on the stainless with .035 stainless wire and a tri mix gas. I would say that if you don't weld a lot of really thin stainless or aluminum, just save your money and get the 211 instead of the multimatic. 211 is around $1200, and the 200 is over $2k, but it does mig tig and stick, which is nice.

Both machines have similar duty cycles and both have the multi voltage plug, which is one thing I love about the machine. I only have one 230v plug in my garage for my 211, but because I can plug it into 110v, I can use it anywhere. Obviously you can only weld about 1/4" thick material when using 110v, but it comes in handy. And when using 230v, that baby will weld just as thick as the bigger Miller 252's. You can run .045 flux cored wire thru it as well, just change the liner.

Not trying to talk you out of the 200, it is definitely a great machine with a lot of nice features, but if you don't think you will use every function quite often, save your $$ and get the 211.

I would love to get an AC/DC Tig but for welding anything over 3/16 I think i'm looking at $4k+ for an inverter style machine. I'm limited to 60amps input at 220V so the Syncrowaves and other transformer style Tigs would be hard to run.

The material thickness or composition I use does not denote what process I am going to use. I just love to TIG and everytime I flip my helmet down I always strive to improve. I used to MIG all the time but now I try and TIG as much as I can. Yes it takes a little more time for prep and such but the results and heat control are so much better IMHO. Plus while tigging this table together I was forced to swtich hand. Boy that was fun.

I have a Dynasty 350 and LOVE IT! Highly recommend it.

A couple things to think about before shelling out 4K+ on a good Tig (I wouldn't even bother buying a bargain one).

Mig welding is easier and faster than a Tig. Tig takes a lot more time to weld and learning time to make a presentable weld is usually longer as well. For welding structural steel like 1/4" angle iron or square tubing etc..., Mig welding is faster and easier to do and works perfectly fine. There is nearly zero advantage with a Tig over a Mig for a lot of materials that just need a weld. For welding metals that are of different thicknesses, especially thinner gauge material, a Tig is a lot better because of the control you have over the heat and flow. Also, for clean, beautiful artistic welds, a Tig is hard to beat.

I use both regularly. For structural things that aren't going to be that visible or not matter as much or are going to be ground down, I usually mig them because it is fast and simple. For artistic welds that are going to be visible or need to be cleaned up for finish work, or for welds that are on multi thickness materials or thing gauge materials, I usually grab the TIG. I personally like Tig welding better, but time is money.

Spool guns work ok for Aluminum but for the best welds (strength and looks) Tig is the only way to go. For stainless, either will work fine.
