Introduction:Â W**7Ni is a kind of low
temperature steel electrode containing Ni with low-hydrogen natrium
type coating. DCRP (Direct Current Reversed Polarity). All-position
welding. The weld metal still has excellent impact toughness under
**0°C.
Uses:Â Used for welding low temperature steel
structures under **0°C, such as *9Mn2V, *6MnVAl, 3.5Ni, etc.

Instructions:
1.The electrodes must be baked under about **0°C for an hour
before welding, and used as soon as baking is completed.
2.The stains on the weldments, such as rust, oil stains, moisture,
etc., must be cleared away before welding.
3.When welding, short arc must be used and stringer bead is
suitable.
