,               Soldering iron maintenance and use:   1, iron temperature: it will reduce function when temperature is high, so please low temperature. With strong recover temperature function. Lower temperature weld enough and protect the temperature sensitive components.    2, clean-up: clean soldering iron with cleaning sponge. After welding, iron oxide and iron carbide welding damage it, heat conduction will decrease. Please clean iron oxide to prevent damage and low the temperature.    3, when not use: please keep lower temperature when don't use it, high temperature will generate oxide and reduce thermal conductivity function.  4, after using: clean solder iron after using, plate tin to prevent oxidation.    Model : 858D  Type : LED digital display  Power consumption: 700W  Output voltage:(AC24V)  Yemperature range: 100°C-450℃  Heating components: chinaware  Handle length: 110cm  Dimension:138mm(H)*10mm(W)*150mm(L)  Weight: 1.45kg            SET-1 Package list :   1pcs 858D(3pcs nozzles)  1pcs Air gun handle  1pcs Power Cable            SET-2 Package list :   1pcs 858D(3pcs nozzles)  1pcs air gun handle  1pcs Power Cable  1pcs Heater            SET-3 Package list :   1pcs 858D(3pcs nozzles)  1pcs air gun handle  1pcs Power Cable  1pcs Heater  3pcs Tweezers            SET-4 Package list :   1pcs 858D(3pcs nozzles)  1pcs air gun handle  1pcs Power Cable  1pcs Heater  3pcs Tweezers  1pcs Solder Wire  1pcs 6-in-1 Solder Assist Tools            SET-5 Package list :   1pcs 858D(3pcs nozzles)  1pcs air gun handle  1pcs Power Cable  1pcs Heater  3pcs Tweezers  1pcs Solder Wire  1pcs 6-in-1 Solder Assist Tools  1pcs Solder Wick            SET-6 Package list :   1pcs 858D(3pcs nozzles)  1pcs air gun handle  1pcs Power Cable  1pcs Solder Iron  1pcs Iron Stand  1pcs Sponge  5pcs Iron Tips (I B K 2.4D 3C)            SET-7 Package list :   1pcs 858D(3pcs nozzles)  1pcs air gun handle  1pcs Power Cable  3pcs Tweezers  1pcs Solder Wire  1pcs 6-in-1 Solder Assist Tools            SET-8 Package list :   1pcs 858D(3pcs nozzles)  1pcs air gun handle  1pcs Power Cable  1pcs Heater  5pcs nozzles            Physical display
