THIS IS MINI Portable OLED T12 solder iron station, you need to prepare a DC 24V 3A-5A power by yourself. Size: 88mm*41mm*38mm NOTE: Iron tip do not work high temperature continuously, the tips will be damage easier. Solder melting point is 183°C, lead-free solder melting point is 227°C, the welding temperature is 300-380°C. 380°C is the temperature of the dividing line. When the temperature is higher than 380°C, iron head oxidation and loss is fast, affect the life of heating core. Higer than 380°C, temperature display also will be beating, the higher the temperature, the greater the beating! Recommended in the 300-380°C for welding work, most of the work can be carried out, the temperature beating is normal.
