Features precise temperature control by using a thumbwheel potentiometer with a 1-to-10 setting. Tip temperature adjusts from 150°F to 850°F with ±2% accuracy. The lightweight, slim-line 25-watt soldering iron is ideal for delicate soldering applications. It features a 54" silicone cord that terminates with a 5-pin connector for easy plug-in to the power unit. Tips easily slide-on over the heating element, providing fast heat-up, optimum thermal efficiency, and quick tip replacement. Solid state circuitry converts 115VAC line voltage to 24 volts, and zero crossing electronic switching eliminates RF interference and magnetic fields. All this combined with a positively grounded tip, make the Model 660TC25 ideal for use with heat and voltage-sensitive components. Comes complete with power unit, iron holder and sponge tray, soldering iron with 2IC tip, and 3-wire power cord cord.
