Glow plugs consist of a threaded body and a heating element built into the body.
When the glow plug is turned on, a current of 30 A flows through it. At the same time, the heating coil heats up the candle. The control coil during heating limits the current to 15-25 A and limits the heating temperature of the candle, which helps to increase the service life of the candles.
