Notes on usage:
1. Clean up the contaminations on the base metal to avoid porosity and crack.
2. Dry the electrodes at 300-350℃ for 60 minutes, and keep at 100-150℃ before using.
3. For vertical downward welding, manipulate the electrode as shown in figure, Do not use balance arc.
4. Do not exceed the range of proper currents. Over heat input decrease hurt the impact toughness.
