can I use a wall dimmer switch to control the heat of my soldering iron Answered

or a strip heater for bending plastic made from about 12 inches of heater element from an old toaster or hair dyer? do they use PWM,or just a big variable resitor?

Yes, you can. The soldering iron is just a resistor, like a light bulb, so which type of dimmer you get doesn't matter. On mine only the upper third or so gives a usable amount of heat for wax sculpting with a low power (10 watt?) iron, so you might want to have a high power iron for more accurate control.
