Homebrew PCBs

Copier fusers can be up to a 800-900 hundred watts, much more powerful than
most laminators. It might even work better. Copier fusers are high powered
in order to reduce warmup time, vs a laminator is on all of the time. You
will have to tweak with the controller though, as the parameters are going
to be a lot different with copper as compared to normal paper handling. The
copier controller is designed for very fast ramp rates, I don't know if you
can slow it down so that it will deal with the slow changes caused by copper
laminate.

Good luck
