Note:

Before welding, it's necessary to clean the work piece and remove the impurityes such as oil, grease rust and moisture, bake the electrode at the terperature of about 350 degree C for one hour, carried out under short arc and suitable for narow path. Using DC, the electrode must be connected with positive polarity.
