  • Wattage drawn on welders

    Is there a Miller engine driven welder generator capable of powering a dynasty 280?

    A Bobcat 250 will run it.. Not really understanding the question, I guess. Unit takes 230 power, so multiply it by the amps you'll likely need to get the watts. Then figure the machine you'll need out.

      Welcome to the forum obiewelds,

      as Cruizer mentioned WATTS= Amps x Voltage

      You'll have to look at the specs of the machines you are interested in.

      1- Miller Dynasty 280
      http://www.millerwelds.com/pdf/spec_sheets/AD4-9.pdf
      rated specs 235 WELDING amps will draw 30amps at 230v

      30amps x 230v = 6900watts.

      You need an engine drive with at least 6900watts of auxiliary generator power.

        Thank you fellas. I'm sorry for my lack of explanation I have little knowledge when it comes to electrical and hooking the welders up. This was a big help.

          The watts that enter in the wellder can be calculated as LINE VOLTS x WELDER INPUT CURRENT . ( example: 230V X 55 amper = 12650 watts )

          This is the max power required by the welder machine.


          If you want to convert to HP , just divide by 750 (example: 12650 : 750 =16.86 HP.)

          However if you are not using the full welder current a gen of 7.5 HP or less can supply the power required .

              Not 100% sure what relevance electrical motor hp has to do with this case. . Unsure why we would even bother with Electrical HP. Soooo, whats the reasoning behind your suggestion?[/QUOTE]
