Some guy is selling a Millermatic 200 welder, made in 1992. Comes with

it would be for myself and not for resale.

Does "and everything" include a bottle with regulator and flowmeter? What kind
of gas? Spoolgun? You can get a manual from Miller, in fact it's
http://www.millerwelds.com/om/o1303p_mil.pdf for the generic one or you can go
to their manual page http://www.millerwelds.com/service/ownersmanuals.php and
type in the serial number of the machine and then you'll get a manual specific
to your machine (Miller revs their machines all the time). The manual shows the
machine comes with an optional spot pulse timer panel.

It looks like that machine has a 14-pin spoolgun connection.

OK, guessing. I don't know where you are, or if the machine has a bottle and a
reg/flowmeter or a spoolgun. Assuming it does not, nor has the optional spot
panel, I'd say $350-450.

Look closely at the mig gun. A gun that old might be absolutely beat to death. A
new MIG gun would run you about $150.

If it has the bottle/flowmeter, I'd add $100. If it has a working spoolgun I'd
add $200.

That's my best take. I'm pretty new to the wirefeed world, though.

At this site http://www.keithcompany.com/Welding%20Equipment-184.asp
there are several MM 200's for $300 with no cable, no gun and estimated
repairs less than $300 more. There is a MM 250 for $900, used.
A brand-new Miller 210 is available for $1250.

If everything is there and it works, I would say $400-$500 could be a
reasonable price.

Thanks. Makes perfect sense. Do they need 30A at 220V?

Read the manual! Since I looked at it and still have it, I took a quick look.
No, it uses 40 amps at 220V.

When you go look at it, if you don't buy it on the spot and you take away
unresolved questions, be sure to write down the serial number as any Miller
person will instantly ask you for that number if you call to inquire about part
availability. Number from the machine, number from the gun (if it has one).

This welder is a CV machine. It stabilizes the voltage with a large bank of huge
electrolytic capacitors. Such large capacitors are known to dry out and fail
anywhere from 10-30 years. Since this machine was last manufactured in 1991,
it's conceivable that it may need some caps replaced. They might be expensive.

Miller blue paint is pretty easy to match. I found a can of Zynolyte Deep Blue
that matched the color real well, but sadly that color has been discontinued.

What kinds of caps are those?
