Looks like it can be driven at 100 to 200W but depending on the resistance this might be a 220V or 120V unit. The problem with running a 220V unit at 120V is that you only get 30% of the power output-- probably will be difficult to get it hot enough.<br>
Could you please quickly touch the wires with a multimeter?<br>
From the color of the thermocouple wires, it seems that it is probably a K type thermocouple-- per http://en.wikipedia.org/wiki/Thermocouple<br>
and Sparkfun does cell a thermocouple amp.</p>

I would imagine starting at 12 volts to be safe, treat it like a big resistor. Once you get a measure of resistance you can figure out how much power to start with. What would be nice is to know the maximum operating temp, both at the tip, and of the coil its self. Then again this is asking a lot for a replacement part, we clearly have less conventional...purposes in mind.<br>
Chad, i know his is a late reply, but did you ever get this? and if so did you learn any thing about it?</p>

I'm currently making a reflow soldering element, which involves a 240V PWM'd output (and also a 12V 20A pwm'd output, but this would only give 240W). Note that the base station is separate from the actual hot-plate element. It would be nice if I could just use this element and a tip to create a cheap add-on for the base station that would allow me to do Hot-air reworking.</p>
