The Vintage is no longer a current offering for Miller. It is a pulsed GMAW all in one power source producing 200 amps at 60 percent and capable of welding 1/2" steel in a single pass.
================================================== ======
The Vintage was NOT a pulse machine. It was the bigger brother to the MM210 with the same type of Tapped transformer control. It never had the provisions to do pulse mig as that would need a solid state or inverter unit. The Vintage is old school tranformer/rectifier. A great machine....We just have too many units in or near that product size and with the new solid state digital units like the 251, sales of the Vintage have been fair at best.
Thanks.
Andy

Thanks! I wonder why Miller discontinued this machine? They also ditched the 252 Tapped Slope machine. There are 2 great GMAW machines gone from the product line.
I know where there may be a new Vintage for $1419.00. Roberts Oxygen has had one listed on their website for awhile.

If my PowCon died that's the first machine I would try to find. Plenty of MM251s around.

Yes, it will do spray arc just fine. I believe I would choose the 98% argon / 2% oxygen and that way you will have it if you decide to try a gas- shielded stainless wire. The Vintage will probably spray with 92% argon / 8% ccarbon dioxide, but the 98/2 will be hotter and a more versatile choice. My guess is your have access to roughly 28-30 volts with the Vintage power source.

No. The MM210 maximum voltage output is arund 25 volts. It does not have enough voltage behind it to spray with 75/25. Also the 75/25 Ar/CO2 mix is not designed for spray. Add another 5% to 10% argon and it will be more suited to spray transfer. I have sprayed with 75/25, but your really must have the higher CV output to do it. It will start into the spray mode around 36-38 volts. One of the hotter gases is your best bet.

Thanks all solid info I have done spray in school but with a lot more machine Invision 354mp Argon and Helium mix not sure what mix. I will be switching to a little hotter gas after this tank, it'll be nice to be able to push the mm210 if I need to, Don't do much heavy work mostly mild tube and Al tube and plate.

Re: Dan, what settings

Thanks

Paul, I can t give you an exact answer to your question because I was just playing with machine, and was paying more attention to the arc quality then my actual weld results. About the only help that I can supply for now is with the wire speed meter reading about 420 , i had to set the voltage between 26 and 27 to produce a good spray with 90/10. Sorry i can t help more then this.
