Precautions for the use of constant temperature electric soldering iron
1. Before using the soldering iron, check whether the voltage used is consistent with the nominal voltage of the soldering iron;
2. The electric soldering iron should be grounded;
3. After the electric soldering iron is energized, it is not allowed to knock, disassemble and install its electric heating parts arbitrarily;
4. The electric soldering iron should be kept dry and should not be used in excessively humid or rainy environments;
5. When removing the soldering iron head, cut off the power supply;
6. After cutting off the power supply, it is best to use the residual heat to put a layer of tin on the tip of the soldering iron to protect the tip of the soldering iron;
7. When there is a black oxide layer on the tip of the soldering iron, it can be wiped off with abrasive cloth, then powered on, and tinned immediately;
8. The sponge is used to collect tin slag and tin beads, and it is appropriate to pinch it with your hands so that the water does not come out;
Nine, do "5S" well before welding, and do "5S" after welding.
