    Default Duty Cycle, how often you really exceed it?

    I know I don't weld as hard as the professionals but I can't remember ever exceeding my duty cycle. My lil Blue Star Jr. is a tank. It says only 60% @90a but I know it runs hotter than its max 100a and have definitely exceeded the 6 min on "MAX". Haven't seen the light on my mm211 either. Anyway I know most of you guys probably have,I'm just throwing the topic out there.

    I had a blue star.. it was a nice lil machine. I wish i still had it for little stuff, i liked how light it was. I really dont know what happens to a blue star if you exceed the duty cycle.. i dont think it shuts off the arc but i dunno... does it? I know the millermatics shut of... they shut off for about 15 minutes, i do it all the time with my 180

    Yeah that lil thing is my dude. I wouldn't sell it for nothin'!! I think it's really underrated. I mean Miller makes a helluva engine drive, so doesn't surprise me.

    Hard to do as a hobby weldor.

    Even a 20% duty cycle 2mins out of 10

    watch your clock for 2 minutes straight


    Most of the time you are moving around, starting and stopping so hitting the duty cycle is rare. If you are then you need a bigger machine.

    My girl has always said my duty cycle needed to be longer and that I really do need a bigger machine.

    Lol, Boobcat! I hit my duty cycle on my Diversion 180 all the time on aluminum, and quite a few times on my 211 as well, the spool gun can't keep up at all! Been through 100 tips in a year!! But gonna love the upgrades!! :-)

    Default Duty cycle... or Thermal shutdown

    It seems like a lot of us are confusing duty-cycle with thermal shut-down.

    Hit the 50 amp breaker in the electrical panel with the Syncrowave so many times, I upgraded to a Dynasty.

    Aluminum takes beaucoup amps.

    Have never tripped a machine's thermal protection shutdown, even the little 150 Maxstar's.
