[0001] The invention relates to the technical field of welding accessory equipment, and in particular to a welding rod insulation barrel. Background Art

[0002] In the welding process, especially when welding pressure vessels, boilers, and nuclear power equipment, the drying requirements for welding materials are very strict. After drying, the welding materials have a strong ability to absorb moisture. The solution is to store the welding materials in an insulated container at 80℃-100℃ after drying to prevent them from losing temperature and getting damp. Therefore, the welding material insulation barrel is an important storage container for moisture-proofing welding materials at the work site to ensure welding quality.

[0003] The welding material insulation barrels currently on the market are not equipped with power supply after power outages. They cannot be powered for insulation when used away from a power source. They are also unable to automatically detect and alarm whether the insulation barrel lid is closed after the welder takes the welding material. This causes the welding material to be exposed for a long time, causing the welding material insulation barrel to lose its insulation function, resulting in the welding material losing its protective effect, which is not conducive to the subsequent use of the welding material.

[0004] Therefore, it is necessary to provide a welding rod insulation barrel to remind the closing of the insulation barrel cover and the loss of temperature of the welding material insulation barrel, so as to remind the welder to close the insulation barrel cover in time and ensure effective protection of the welding material.
