D&H 1250 is a basic coated electrode depositing monel weld metal. Ideal for welding of monel to monel, Ni-Cu alloys to themselves, Ni-Cu alloy to steels, for welding clad side of Ni-Cu clad steel and for surfacing on steel parts for service against corrosion by sea water, chlorinated solvents, sulphuric acid and alkalies; ideal for marine, chemical, food, dairy and oil refining industries.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300-325°C for one hour.
2. Use DC(+) and minimise heat input by using low current and stringer bead.
