The Weller WLC100 soldering station adjustable heat dial often goes bad because of a failure of the TRIAC switch on the adjustable heat board. To fix the adjustable heat dial we can replace this inexpensive switch. We will need to use the existing Weller iron to de-solder the TRIAC switch and re-solder in the new switch. However, if you own a Weller you most likely have experience using soldering irons, and this process presents little opportunity for injury.  This repair should take less than two hours depending on skill set. There is always a possibility of being burned when using a soldering iron. Care must be used when handling hot soldering irons.
