Notes:

1.The welding electrode is very easy to damp, it should be stored in a dry sealed container, in order to prevent deterioration; Before welding the welding electrode must be baked at about 150 ℃ for 1h.

2.Before welding should be the plate, and according to the welding thickness preheated to 200 200~300℃ then welding, the welding process, welding should be vertical welding surface, the arc should be as short as possible, the replacement of electrodes must be done quickly.

3.Before welding must remove grease and impurities, after welding slag should be carefully removed, and with steam or hot water washed clean.
