  • Voltage Quandary

    I removed the cover from my old DialArc AC-DC 250 to check for dirt daubers and to blow it out.
    The power line configuration jumper was was set for 208 volts. The other choices were for 460V and 230V.
    Obviously, I know very little about electricity by having to ask whether the proper setting is 208V or 230V. Both are close to 220V which I believe to be the incoming line voltage.
    Which setting is correct for standard 220V single phase 80 amp service?
    Also, while cleaning the welder, I noticed that the control panel, in bold letters, labeled the unit as an "AC-DC Power Source"
    I can buy a practically new Miller XR-A Extended Reach Wire Feeder without a gun for $700.00. Would this work with the DialArc?
    If so, does the XR-A unit require a $700.00 gun or can I use an ordinary M series gun and would this be a sensible way to go?
    I need a more powerful MIG than my MM 135. If I could assemble a MIG using this old welder for $700.00, it would be great.
    I really like the old DialArc. It's the sweetest stick welder I have ever used.

    The Dialarc is a great stick welder... it will make a lousy MIG supply...

    for MIG you want a Constant Voltage supply... the Dialarc is a Constant Current supply

    If your line power is 220vac... then strap the machine for 230vac.. (because that is what you really have)

      Thanks for the info.

      What is the 208 volt option for? Where would you commonly find this voltage in the US?

        Here is the link to the Wiki on single phase power... it explains it better than I could..
