Soldering iron came in a $14 USD kit off eBay. Lots of neat stuff, but the iron became so hot as to badly damage a DIY Kit. After a 2nd chance w/ the same results, it was hacked, Heating element of 216 Ohms directly connected to two "hot" wires of VAC ! Has to be runaway current. After much research but before any purchases, it was decided to add a CURRENT LIMITING Xc Capacitor of X2 class to one of the wires, 6uF should do the trick to maintain 5oo mA and 120 volts @ 60Hz.
Will this work?
Did lots and lots of research, and is better than impedance of shaving off 1 to 10 watts to heat energy. The capacitive reactance becomes the current limithing "resistor", but cannot find any schematic or datasheet to show how it is properly done.
