Precautions:
1 welding workpiece should be degreasing, rust treatment.
2. Welding, the gas flow is generally 20 ~ 25L / min.
3 flux cored welding, dry elongation should be 15 ~ 25mm.
4 wire warehouse humidity should be maintained at less than 60%
5 non-vacuum packaging wire storage time should not exceed six months, vacuum packaging wire storage time should not exceed one year.
