As a result, the heater wires tend to suffer from poor electrical insulation, causing current leakage from the tip of the soldering iron to the object to be soldered, resulting in destruction of electronic components such as ICs. In addition, because the heat conduction loss due to electrical insulators is large, it is necessary to heat the heating element higher than the required temperature of the soldering iron tip, which increases power consumption and causes the handle of the electric soldering iron to become hot. was there.
