D&H 1280 is a basic coated electrode depositing a pure nickel weld metal, ideally suited for welding wrought and cast of commercially pure nickel to themselves, welding nickel to carbon steels, overlays on steels to resist corrosion in caustic soda service and marine atmosphere.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300-325°C for one hour.
2. Clean the weld area thoroughly free from all contamination.
3. Use short arc and minimise heat input.
4. Wherever possible weld in flat position only.
