  • Is this Normal? /Millermatic

    I turned on my millermatic 175 just a while ago and I noticed that right when I turned it on the green colored temperature light made a very quick flash probaly less than a second but did not stay on though.I was just wondering if this was normal? I know it probaly don't amount to nothing but so anyways I turned off the machine and turned it on again and it didn't happen.I just wonder why it made a real quick flash when I turned it on the other time.It probaly flashed about a millisecond but I wonder why it did that.I guess it probaly wont hurt the machine but Im just so overprotective of my new welder because I just shelled out 700 bucks you know but I never let my welder get overheated by welding too much and not paying attention to the duty cycle anyway!

    Thanks In Advance!

    I sure hope so

    I sure hope so, since I just got my MM135 to go along with my Syncrowave 180SD tonight...plugged it in, turned it on and the over temp light did the same thing...blinked once.

      If it didn't blink, then how would you know the lamp was working!!!!

      "bulb check"

        When you turn on a cold machine, the thermal light will flash quickly as caps on the board charge and turn on a protection relay on the board. That is the reason for the quick flash.

          i agree. just the initial power surge. the cap was charged the second time.
