Electrode from the electrode core and drug skin, one of the welding electrode core role as electrode conductivity, it is also the formation of the weld metal materials, the quality of the welding rod core directly affect the performance of the weld, the material is specially manufactured high-quality steel electrode welding of carbon steel core is typically 0.08% C low carbon steel, the most throughout the H08 and H08A carbon content and sulfur, phosphorus and harmful impurities have a very harsh restrictions on the common electrode diameter ( electrode core diameter) for 2.5 to 6 mm, length 350 ~ 450mm. Although the welding rod in the general case the resistance to external damage, but can not be ignored due to the custody of poor vulnerable to damage. The electrode is a ceramic product, he can not impact resistant as steel core, loading and unloading can not throw him. Cartons electrode can not be used can not be linked to handling. Certain models of electrode such as the special drying requirements of basic welding rod coatings more than the normal electrode to be handled with care. Under normal circumstances, welding of plastic bags and carton packaging, in order to prevent moisture absorption in the Carbon Steel Electrodes before use, can not be arbitrarily apart, as far as possible be done now with now demolished, it is possible to welding after the remaining electrode sealed . Acid electrode is not sensitive to water, organic rutile type electrode can tolerate higher water content. According to the specific circumstances of the damp, drying at 70-150 ° for one hour, short storage time and good packing, generally from time to dry before use. The basic low-hydrogen electrodes must be dried before use, to reduce the hydrogen content of the electrode, to prevent the pores, cracks and other defects, the general drying temperature of 350 ° C, one hour. Not be in a furnace electrode suddenly placed in a sudden cooling in order to avoid skin dry. There are special requirements on the hydrogen content, drying temperature should be raised to 400-500 ° C, one to the amount of one hour. Drying the alkaline electrode is best placed in another temperature control 50-100 ° C and low temperature drying box, stored and used with the check. Drying  Welding Electrodes, each electrode can not be stacked too thick (typically 1-3) in order to avoid uneven heating in the electrode drying and moisture is not easy to exclude. Open operation, overnight electrode proper custody, does not allow open storage should be stored constant temperature in the cold box, otherwise the next day must be re-dried before use.
