  • Miller Bobcat 225 question

    I have a Miller Bobcat 225 machine that I bought new in 2011 that has very low hours on it. I went out to the shop the other day to doublecheck the hours on the machine and I turned the power switch on to read the hour meter. When done, I forgot to turn the switch off. I discovered this goof the next day so it was probably on for about 12 hrs. Did I screw anything up?? I have a battery charger maintainer on the machine so I doubt it drained the battery down. Anyone ever done this before? In my mind I don't think it harmed anything. Am going to start it and run it later on this week. to see if it runs ok.

    Check and see if it will weld.

      Probably like leaving the ignition in your car on, just sat there waiting for someone to push the start button.

        Just charge or repalce the battery. Don't jump it. You should be ok

          Yes it will weld but not feed wire. I talked to Miller Technical support and they said the board needs to be replaced...ordered a replacement board from Miller Service Parts for $700 which was bad I just received an email saying they are backordered and dont know when they'll have any..

          Would anyone know which relay/component on the board supplies voltage to the drive motor? Maybe I'll take a shot at trying to replace it.....

          Thanks for the responses
