I recently purchased a very nice Teledyne TW-1 Stripall thermal stripper. Mine is the version without the temperature controller and just heats up to Max when the button is pressed.
http://www.teledyneinterconnect.com/products/wire_strippers/wirestrip.aspThe TW-1 also has the option of a controller that sits in line with the 110V supply. I thought it likely that this is just a simple light dinner circuit using a Triac to chop the mains waveform. I am no longer so sure though as the TW-1 is a transformer, so inductive load, as opposed to the resistive load expected by a lamp dimmer.
IIRC simple dimmer circuits do not work well with motors and transformers. Back EMF can even kill the Triac.
Does anyone have the Stripall controller that they can open and photograph please. I would like to know what Teledyne have done to control the voltage fed to the transformer.
The TW-1 is also available with the controller hard wired to it, under the model name TWC-1.
Maybe it is just a simple lamp dimmer circuit with some back EMF protection ? That would surely make the transformer in the handpiece buzz though?
Thanks in advance
