Storage and Handling
- Storage: Store the wire in a dry, cool place, away from moisture and contamination. Keep it in its original packaging until ready for use to prevent oxidation and debris buildup on the wire surface.
- Handling: Handle with care, preferably with clean gloves, to avoid contamination. Ensure the welding area is free of contaminants such as rust, oil, and dirt. Clean the workpiece before welding to ensure high-quality welds.
