After we installed our UPS system a couple of years ago - we noticed that
our lasers were lasting much longer - 4500-6000 hours versus 2000-3000
hours. Don't know if it has a impact on frequency of remelts though.

We have always been told to do triple remelts as follows:
   1) Hit reset button and wait to hear laser fan kick back in
   2) Hit reset button again and wait to hear fan kick in
   3) Hit reset button again
   4) after fan kicks in - monitor laser power until it stablizes
       and then initiate build.
Hope this helps... Regards, Todd Stahlhut
