I recently ran across a Miller 250 for sale for what seems like a reasonable
price. I have a couple questions though.
Does it have dual solenoid valves like my 212?
Will the dual tank platform and axle kit fit on it?
Are there any headaches to watch out for?
Can I use the same spool gun I use on my 212?
Can I leave both a spool gun and a regular gun hooked up at the same time
like on my 212?
I know. I know. My 212 is a great welder, but I have already run up
against its limits a couple time.
I take it this is a Millermatic 250 and not a DialArc 250?
Don't know about dual solenoid valves, generally questions like these can
be answered by reading the manual, obtainable from the Miller web site.
The Millermatic 250 is the last of the analog-controlled 200-amp MIG
welders in the big rollaround case. It has the same basic specs as
the 251 and 252, but it isn't digital and of course doesn't have things
like pulsers. More to the point, it does not have built-in spoolgun
support. You have to add the spoolgun module, part no. 043084, currently
selling for $227.20 on miller4less.com. Then a 30A spoolgun will hook
right up. Don't know if your 212 spoolgun will fit. Yes, you can then use
both the spoolgun and the regular gun at the same time, assuming your
gas connections are made to both. The regular gun's gas connection is
at the back of the welder, while the spoolgun's gas connection goes
directly to the regulator on your cylinder.
I love my MM250. I got mine for $500 with a cylinder of gas, added the
spoolgun module and a 30A spoolgun, and have made about $100k with it
