This very affordable 100 watt soldering iron for the stained glass novice features an ON/OFF switch for safer and more convenient control. Should be used with a temperature controller, for flexibility as well as so not to overheat the tip. Comes with 3/8" shank chisel tip (#6867T). Made with a heat-resistant polyoxybenzylmethylenglycolanhydride handle (Bakelite, for you non-scientists).
