Ignition uses ~ power supply, Can be supplied by AC power via transformer. A voltage-adjusting rheostat and an indicator light or ammeter to indicate the ignition status should be connected in series to the circuit.
The ignition voltage should be determined by testing in advance. Method: Connect the ignition wire and conduct the test in the air. In the case of fuse ignition, adjust the voltage so that the ignition wire reaches bright red within ~. In the case of cotton wire ignition, adjust the voltage so that the ignition wire reaches dark red within ~. After the voltage and time are determined, the voltage, current and power-on time should be accurately measured in order to calculate the heat generated by the electrical energy.
If cotton wire is used for ignition, connect a section of nickel-chromium wire with a diameter of about 50% between the two electrode posts above the flame shield. The middle part of the wire is pre-wound into a spiral several times to concentrate the heat. Then clamp one end of the cotton thread in the spiral and the other end is connected to the sample through the small hole (diameter ~) in the center of the flame shield. According to the difficulty of igniting the sample, adjust the amount of cotton thread overlap.
