GBC H200 Laminator Temperature Control Circuit mods
2011-06-06 by Terry Ilardi
I have a GBC H200 laminator that I have modded with the Pulsar mods. I've measured the temperatures on mine and determined that at the higher heat setting the rollers heat up to about 300 F. I use the laminator these days mainly for applying photoresist to aluminum panels and toner transfer for silk screen. For both uses I think would need fewer passes if I could raise the temperature a bit (I've read that the unit is supposed to get up around 183 C-mine is nowhere near that high). I have seen other GBC laminators modded to increase the temperature (generally by adding some resistance into the temperature control circuit). Has anyone tried that with this model? Or has anyone reverse engineered a schematic for the temp control circuit? (I haven't been able to find that on the web). Thanks. Terry
