Ordinary solder melting point is 183C, normal solder melting point is 227C, usually the welding temperature is 300-380C, 380C is the temperature of the dividing line, higher than 380C, iron head oxidation and loss is extremely fast, seriously affect the heating core life.The Higher than 380C temperature display will be beating, the higher the temperature, the greater the beating Recommended in the 300-380C for welding work, most of the work can be carried out, the temperature beating is normal, does not affect the use Set: AOutput Power: 65WTemperature Stability: 2 degrees CelsiusOutput Temperature: 100-400 degrees CelsiusInput Voltagle: 12-24VTotal Length: 168mmInput:DC24VMaterial: Plastic + Metalcolour: As shownPackage Contents:1 x Soldering iron control terminal1 x wrench3 x Soldering Iron Tip(-I,-BC2 ,-K)Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
