Welding Electrodes custody, paying particular attention to the environmental temperature. The air relative humidity and the higher the temperature, the higher the water vapor partial pressure, the drug skin more easily the absorbent. When the partial pressure of water vapor in air ≤ 5mmHg, the small amount of drug skin absorbent, but is generally recommended in the air relative humidity is below 60%, and to leave a certain distance of the floors and walls. (About 30 cm) to distinguish between the ast Iron Welding Rod models, specifications, you can not mix the wrong. Transport electrode, stacking process should be careful not to damage the drug skin, the poor welding rod on drug skin strength: high strength steel welding rod, stainless steel welding rod, welding electrodes, cast iron welding rod and so on, more should be careful. Electrode stack can not be too high.
