Glad to see that it's an .030 wire.

Based on the info you have provided, you are running the MM 210 at lower output settings then what the 1/2" .035 doorchart setting on the MM 251 produce. If you want the MM 251 to output similar voltage and amperage values, which could possibly result is similar results to what you are achieving with the 210, you need to set your voltage around 21-22 V and your wire speed probably somewhere in the 380- 400 range. The wirespeed meter on the MM 251 isn't exact, so you might have to go higher yet. The meter on my unit is off by about 20 IPM.

Dan,

Do you think the wire speed variance is due to your higher voltage, or does Miller compensate for voltage?

[Bulldog]

Hi guys,
I went out this morning and tried the settings that Dan suggested and it was pretty good. I wound up at 22.5 volts and a wire speed of 393. It still isn't perfect but it's pretty good. I think that some of the trouble is me. I'm finding that I'm so wrapped up in the look of the weld I'm going slower then I normally do. I guess I need to get a bit more comfortable with the machine and things will be fine.

Alan,

The difference has nothing to do with my higher input voltage. On my unit the IPM the machine feeds is actually lower then the value on the meter.
The difference more then likely has to do with the fact that the circuit board that regulates this has fixed resistances on it, that have a + or - tolerance range. If Miller went with resistances that have a 10% + or - tolerance for there value, this can create a fair amount of error. To make the tolerance on this circuit tighter, i wish Miller would have used a vqariable resistor in the circuit so that the meter could be calibrated for each unit.

Dan,

Thnaks for the clarification.

So once a guy figures out the variance, (assuming it's constant), and figures out which circuit, and which resistor on which board could be changed to a POT (potentiometer) then life is good eh?

I'm sure most guys find it easy to put little marks or stickers next to the voltage and WFS controls for those commonly used settings anywho.

So can't a guy just run the wire out, and measure how much wire comes out in 10 seconds? or does the wire feed speed change when your shorting to a work piece and loading the machine?

BULLDOG: If you lived closer (I live in Raleigh, NC) I would buy the MM 210 from you. I was planning to buy a MM 251, but the MM210 would serve my needs.

Bulldog,

You said that your using Spray Transfer Mode, and using C-25 gas? Which is 75%AR/25%Co2. If this is the case you might want to switch your gas or buy a smaller tank of 95%Ar/5%Co2, this is a perfect mix for Spray Transfer with the MM251. I know some guys can get spray with C-25 gas, but the MM251 in my mind just isn't big enough to do it. You might want to look into this, also there are some guys who think they're in spray when they aren't, i'm not sure what your welding background is but i just want to cover all areas, you know i've always gone to weld and the weld will look like $%[email protected], and you know what i forgot to turn the gas on. So sometimes it's the simple things. Just a few suggestions.

210

Hey Bulldog

Do you have all the original stuff that came with the 210 like paperwork, video etc?

I guess it would still be under warranty?

What all comes with it - consumables, tank?

Thanks
Dave

Hi guys,
Well the MM251 and I are getting along pretty good these days. I guess I'm getting the hang of the thing. Thanks for all the help! Now about the MM210, I have decided to hang on to it. I can think of alot of reasons to keep it and not alot of reasons to sell it. I have received alot of e-mails about it and I appreciate all the interest but it would be best if I hung onto it.

Hey Bulldog,

Why did you go with the MM251 after having the MM210 for such a short time? I have read a lot of great things about the MM210 and assume that the MM251 is a better machine, but I am courious as to why you choose to upgrade? Is there something you now don't like about the MM210 that the MM251 corrected or is it just more output that you require?

Just courious.

Thanks!
Bill
