  • Difference between Maxstar 200sd and CST 280

    Can anyone tell me the differences between the Miller Maxstar 200sd and the Miller CST 280?

    I know the CST 280 operates on 220 and up. Does the Maxstar 200sd operate on 115?

    Any other differences?

    Which is the choice to own?

    Here's MILLER'S info 200

    CST 280

    The 200 will run 115 volts and Max AMPS is 200. At 115 volts you have 100 % duty cycle at 90 amps with stick and at 220 volts 100 % is 125 amps with stick.
    This also has digital readout and is better for tig

    The CST 280 at 220 volts has 100% with stick is 150 amps. Dial adjustments for settings and it will do tig.

    As far as choice, what type of work and material will you be using ? Are you gonna be tig welding much or more stick welding. What about a mig ? We need more info on your usage.
    To make it easy, get a Miller 211 mig for thin material or the 252 for thick, CST 280 for stick, the ''NEW'' 210 syncro , and throw in a TRAILBLAZER engine drive.
    Ok, now go spend some money.

      As stated, the CST will not run on 120v. The max star will run on 120v at reduced welding amperage.
      The CST 280 is a 280 amp machine on 3 phase power only. On 230 single phase power, the CST 280 maxes out at 200 amps weld output.
