Duty cycle...Can you super cool?

[BigBurban350]

I was reading the manual for my welder and read about duty cycle. I can only weld 2 minutes outta 10 and wait 8 minutes to cool. If I add like two decent sized fans to aid the existing fan can I increase the duty cycle or just to decrease cooling time? /forums/images/graemlins/thinking.gif

My little 110 volt welder has a thermal shutdown if you exceed the duty cycle. With a fan or any good airflow near the welder it will weld much longer before deciding it needs a rest /forums/images/graemlins/smile.gif

The stock fan in that craftsman is pretty powerfull. More fans won't help much. I almost never hit the auto cut off on my welder. Make sure you leave it on in between welds and you should be fine.

Rated duty cycle is at maximum amperage. As amps go down, duty cycle goes up proportionally. So unless you weld at the upper limits of the machine, I wouldn't worry much about it.
