Several matters that must be paid attention to before using a soldering iron
1) Before using the electric soldering iron, make sure that the power cord and protective ground wire are in good condition.
2) The soldering iron should not be air-heated for a long time during use, so as not to burn the soldering iron tip and core.
3) When the soldering iron is not in use, put it on the soldering iron stand to avoid scalding other items.
4) During the use of the soldering iron, it is necessary to regularly check the temperature of the soldering iron and whether there is leakage. If the temperature exceeds or falls below the specified range or the leakage should stop using, check twice a day and fill in the record.
5) When the soldering iron is not in use, turn off the power and unplug it.
