To increase the heat of the welding process.
To provide a decorative finish to the weld.
How should electrodes be stored to maintain their quality?
Store electrodes in a cool, dry place, in airtight containers.
Keep electrodes in a humid environment to prevent drying out.
Store electrodes in direct sunlight to enhance performance.
Store electrodes in open containers to allow air circulation.
