Portable gas shield welding wire dehumidification and dampproof device

The utility model discloses a portable gas shield welding wire dehumidification and dampproof device which comprises a welding wire box, an insulation and heat preservation layer, a heating resistance wire, a temperature sensor, a humidity sensor and a control panel. The insulation and heat preservation layer is arranged on the inner wall of the welding wire box, and the heating resistance wire is mounted on the inner wall of the insulation and heat preservation layer and is controlled to be turned on and off through the control panel. The temperature sensor and the humidity sensor are both mounted in the welding wire box, and the signal output end of the temperature sensor and the signal output end of the humidity sensor are connected with the signal input end of the control panel. The control panel is mounted on the outer wall of the welding wire box, and an air exhausting opening which is communicated with the inside and the outside is formed in the wall of the welding wire box. According to the portable gas shield welding wire dehumidification and dampproof device, welding wires in the welding wire box are subjected to real-time temperature and humidity detection, dehumidification and dampproof treatment is automatically conducted on the welding wires according to a preset temperature value and/or a preset humidity value, it is guaranteed that the welding wires are kept dry for a long time, when the welding wires are used for gas shield welding, cold cracks and bubbles can not be generated, and the gas shield welding quality is improved.
