Maintenance-free ignition device without welding rod

The utility model discloses a maintenance-free welding-rod-free ignition device which comprises an ignition device body and a high-voltage ignition head arranged in the welding-rod-free ignition device body, and an igniter is arranged in a shell of the ignition device body. When in use, the end cover of the igniter is unscrewed, the igniter switch button is pressed down, the igniter generates highvoltage, the high-voltage ignition head is excited to generate flame, and then the non-welding electrode can be ignited. When the device is used, the device does not need to be supported by externalenergy equipment. Ignition is conducted in a mechanical mode, daily maintenance is not needed, use is available at any time, the application effect is not affected by external factors, and action reliability is high. The high-voltage ignition device can be ignited only by generating a high voltage of more than 1KV, and is high in safety. The ignition device is low in cost, simple in structure andeasy to implement, and has
