Note:
1. The flux must be baked at 350ºC and kept warm for one hour before use.
2. Rust, oil, moisture and other impurities must be removed from the workpiece before welding.
3. Small current and slow welding speed are required when the groove welding is done to prevent cracking.
4. When using recycled flux, appropriate amount of new flux should be added for mixed use to avoid welding defects and poor bead surface forming.
