  • Is there a conversion kit for this......

    I have a Miller Econo-Twin Arc welder, can I use it as the power source for wire welding? Is there such thing as a mig accessory that will attach to an arc welder for power?

    The processes are different. Stick uses a Constant Current source, while MIG is a Constant Voltage source.

    You can get spoolguns, like a ReadyWelder, or expensive voltage-sensing portable wirefeeders but these are usually for flux-cored wires, and not the thin stuff that MIG is generally preferred for.

    I've never actually used a ReadyWelder spoolgun, so maybe do a search for more specific info on whether or not they are worth anything.

      Both of my VS feeders are capable of running SMAW or FCAW and I was welding 20ga today with .035 NR 211 MP using one of them. You won't get as good a result with cc as with cv and it will take some getting used to. If you look around you can find them pretty reasonable. I gave 450 for my Hefty cc/cv and ln-25 together.
      Lincoln: Eagle 10,000, Weld-Pak HD, Weld-Pak 155, AC-225, LN-25 wirefeeder
      Miller: Syncrowave 250DX Tigrunner
      Westinghouse: 400+ amp AC
      ThermalArc Handy wirefeeder
      1 Harris, 3 Victor O/A rigs
      Arcair gouger
      Too many other power toys to list.

      Do it right, do it once. And in all things ya get what ya pay for.

        I'm sure you meant GMAW.
