Using microcomputer processor PID programmable temperature control technology. Preheating station is to use a glaze layer having a high thermal effect, good thermal shock resistance of the ceramic as the substrate, high-quality nickel branded alloy wire once sintering.It has a high thermal effect, overall good, good thermal stability, uniform heating, high dielectric sngth, clean, easy to install and so on features. Air Gun heater use ceramic heater.heating elements firmly wrapped around the model ceramic, rapid and uniform heating.Use the upgraded version fan, the airflow larger than the ordinary fan, spiral out of the wind, long life. Soldering iron part using Imported heater.heating up rapidly, temperature stability, long service life; antistatic design to prevent electrostatic damag to delicate SMD components. The machine has a self-test function.full intelligent over temperature, short-circuit, open circuit, overload and fault display and protection functions., Manufacturer: JTRRDDEW
