Specification: Controller: STM32 V3.1S Input: AC100-240V Temperature: 50-480 Max Power: 120W Display: 1.3inch Power Supply: 24V 5A Tin Lelting Time: <8s Battery: 3V Size: 175 x 11.5 x 9.5cm Note: The tip is not continuously working at high temperature, which is easy to damage the tip The melting point of common solder is 183, the melting point of lead-free solder is 227, and the general welding temperature is 300-380 . 380C is the boundary of temperature. When the temperature is higher than 380C, the iron head will oxidize and lose rapidly, which will seriously affect the life of heating core The temperature display above 380 C will jump, the higher the temperature, the greater the jump It is recommended to carry out welding at 300-380, most of the work can be carried out, and the temperature beating is normal, which will not affect the use The soldering iron used in this welding station is a brand new soldering iron head. Because the resistance of the new iron head is not stable, the temperature will jump or error, which is a normal phenomenon. After multiple use, the stability will gradually stabilize.
