Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. Iron tip do not work continuously high temperature, high temperature work is easy to damage the tip! Ordinary solder melting point is 183℃, lead-free solder melting point is 227℃, usually the welding temperature is 300-380℃, 380℃ is the temperature of the dividing line, higher than 380℃, iron oxidation and loss is extremely fast, seriously affect the heating core life, The Higher than 380℃ temperature display will be beating, the higher the temperature, the greater the beating! The soldering iron used in this soldering station is a new soldering iron tip. Due to the unstable resistance of the new soldering iron tip, the temperature will jump or ERROR, which is normal. After several times of use, the stability will gradually stabilize. Recommended in the 300-380℃ for welding work, most of the work can be carried out, the temperature beating is normal, does not affect the use!
