Notes on usage:
1. Dry the electrodes at 150℃ for 30-60 minutes before using.
2. Clean up the contaminations on the base metal to avoid porosity and crack.
3. Use back-step method to prevent arc starting from blowholes.
Do not exceed the range of proper currents. Over heat input might decrease the impact toughness.
