Notes on usage:

1. Clean up the contaminations on the base metal, groove and pass to pass with stainless steel brush.
2. Maintain short arc length. Moving range should be controlled within 2.5 times of the wire's dia when you are welding with weave method.

3. Dry the electrodes at 300—350℃ for 60 minutes before using. Take out consumables for half day consumption and keep in the environment at 100—150℃ during welding process.

4. Use lower current to prevent from crack and minimize base metal dilution.
