60W electric soldering power interpretation

60W electric soldering power interpretation ：
60W means the maximum power is 60W, when the soldering iron is just plugged into AC. The soldering iron changes from cold to hot, and the maximum at the beginning is up to 60W. We can see from the power meter that the constant power is about 25W when the temperature rises and reaches the maximum temperature. However, when you weld a relatively cold object, the temperature will drop, and the power will rise. When AC is first plugged in, the temperature rises rapidly and the power drops rapidly.
