That's a clue there then, the one I have is quite "cool" and the manual
states that it's 120C. I think 140C is what's needed, at least for
press'n'peel paper.

I've had excellent results by tacking the p'n'p paper to the copper by
running it through the laminator then putting it face-up on a newspaper,
kitchen paper on top and then resting an iron (set to Linen) on top for a
minute. Then back through the laminator but corners first otherwise it
doesn't get an even press.

Sure, makes it a quick and easy process.

I didn't find any of the fine detail that I needed :-(

One of their laminators is listed in the Yahoo database, but there's no
detail on how to modify the drive mech to accept the thicker than pouch
thickness PCB material.
