Who has one and what do you think about it?

Do a search, there is a ton of good info about the mm200.

Not the MM200 of old the New Multi Matic 200 that just came out. The numbers system is a bit confusing...Bob

So far so good

I got one, have only used the spool gun on aluminum. 1/8" to 3/16". I am a beginner and doing OK.

Our school just got two of them finally got a welding stand built will be using them tomorrow. Only thing i dont like so far is the access door how it lifts up the machine when opened

Elevation of Base for Door Clearance

I took a couple of short 2X4s and made 2 dadoes in each one to elevate my Multimatic a bit. This way, I can open the door without lifting the machine off of its base. You can also see an extension cord that I made out of previous 110V 10-3 extension cord. This cord was 50' originally and I cut it down about fifteen years ago to work on a 220 3 HP Air Compressor. Then I installed new plugs and receptacles on it and it's now about 45'.

Note, I bought my Multimatic 200 in September from Baker gas when the offer for the free FX welding table was available. I really like the table too. The machine welds like a dream on MIG and C25. I plan to try some stick welding and flux core welding when the weather gets better here. Previously, I had never done any MIG welding. However, I did do some Ox Acetylene welding and stick welding about 40 years ago when I worked as a diesel mechanic.

Multi Matic 200

Dude I got this machine, 3 days ago and it is bad ASS! It stick welds like no other welder I have ever used, the mig welds excellent and the tig is in the mail... With a full spool of ER70S in it and the leads it wieghs about 45-50 Lbs (ground and factory mig steup.) The MVP feature is also pretty freaking sweet to, Like I said I just got it but I love it!!!!!

I've had mine since February. I really love it. I'm just a hobby welder, but I've used the Mig, Stick & Tig and am thoroughly pleased with it. Best welder I've had. I really like the auto-set elite feature.

For any of you multimatic 200 owners;

Lift TIG?
AC/DC TIG?
How does it do with AL on TIG

thanks

The Multimatic 200 is a dc only machine. It will not tig weld aluminum. It is lift start dc tig only. You have to use a spool gun to mig weld aluminum.
What I don't like about the Multimatic 200 is that it is a 200 amp machine in mig (CV) mode only. It stick and tig mode (CC), it is only a 150 amp machine. Not sure why Miller designed the machine with such a de rating between cc and cv modes.

I have one and love it....haven't used the spoolgun yet but I'm sure I'll screw with that soon

Thanks for the 2x4 idea. It worked out great. Someone went to a lot of trouble to design that bottom to lock into some kind of mounting base. I was going to try and make the dadoes narrower until I realized the bottom is designed to dovetail into something. So, unless I wanted to measure and cut angled dadoes then I just needed to make them wide enough for the dovetailed flanges to fit into. I sent a note to Miller asking if there was some sort of mounting adapter and they answered that the best way to do it is basically just as you recommend. They said ------- "No, we do not have a slotted assembly to mount to a cart However, you could use two blocks of wood and slide them between the dovetail flanges. Then mount the blocks of wood to the cart. Then drill holes through the flanges and fasten the welder to the blocks of wood with screws."

Derating between CC and CV Modes

What I don't like about the Multimatic 200 is that it is a 200 amp machine in mig (CV) mode only. It stick and tig mode (CC), it is only a 150 amp machine. Not sure why Miller designed the machine with such a de rating between cc and cv modes.

My guess is that the CC part uses the circuitry of a Maxstar 150STL while the CV circuitry is new.
