Vertical Welding φ1.2 150~250 24~28 20

Instructions:
1.The oil stains and rust on the weldments should be cleared away.
2.When welding, the gas flow rate is generally 20~25L/min.
3.When welding with flux-cored welding wires, the extension elongation should be 15~25mm.
4.The humidity of the welding wire storerooms should be preserved below 60%.
5.It is not suitable for non-vacuum-packed welding wires to be stored for more than half a year, and it is not suitable for vacuum-packed welding wires to be stored for more than a year.
