Electrode exposed in the air for a long time, will absorb the moisture in the air, let the electrode be exposed to moisture, in the welding process, the high temperature will be generated, water molecules will be decomposed, oxygen combustion, hydrogen left in the weld, forming irregular small pores, over time will produce cracks, is now we say hydrogen cracks.Therefore, the existing welding electrode is mostly installed in the insulation box. The common insulation box is composed of the main body and the cover. The upper cover should be opened and taken out, and then the cover should be covered so that the welding electrode can be kept in the insulation state
 

The design of TD-5 incubator can reduce the welder's working procedure. It only needs one hand to shake the rod to produce a heated electrode without opening and closing the lid section. The colleague does not need to open the lid frequently and the heat inside cannot be lost, which can better ensure that the temperature of each electrode can achieve energy-saving effect.Because it is not necessary to open the cover to remove the electrode can effectively prevent the welding rod because the welder forgot to close the cover caused by secondary moisture.At the same time, two stainless steel heating tubes are built into the tank of the heat preservation box, which can ensure that each welding rod is heated proportionally, and more effectively prevent secondary moisture exposure.
