Additional information:

• Store in a cool and dry place, away from moisture and humidity
• Re-dry the electrodes at 350°C for one hour before use
• Remove rust, oil, grease and dirt from the base metal before welding
• Use a short arc length and a weaving technique to avoid slag entrapment
• Clean the slag and spatter after each pass
