Features: OOTDTY This is a MINI portable T12 OLED soldering kit, You need to prepare the DC 24V 4A power supply by yourself. Note: the iron drill does not work continuously at high temperature, high temperature operation is easy to damage the tip! The usual melting point of solder is 183 ° c, the melting point of lead-free solder is 227 ° c, usually the welding temperature is 300-380 ° c, 380 ° c is the parting line temperature, higher than 380 ° c, the oxidation and loss of the iron head is extremely fast, the heating core is seriously affected, and the display of temperature higher than 380 ° c will beat, The higher the temperature, the greater the runout! Recommended at 300-380°c for welding, most of the work can be carried out, temperature runout is normal, no effect on use! If low temperature can be used, then not high temperature: T12 is a fixed temperature control, recommended operating temperature control between 300 °C - 380 °C, higher than 380 °C damage the coating of the soldering tip and reduce the service life of the PTC! Package Included: 1 x T14 Iron Handle 1 x MINI OLED T12 Controller 1 x T12 Soldering Iron Tip (T12-K by default)
