E6011 A lightly coated, all position electrode. It is recommended for general purpose work with 225 amp AC welders.
E6013 Intended primarily for sheet metal welding when superior bead appearance and easy operation are more important than speed. Especially suited for downhill and vertical down sheet metal welding using a drag technique. AC operation is excellent even with 225 amp (low open circuit voltage) welders.
E7018 An efficient general purpose electrode suggested for all the "General Applications" listed above. Iron powder in the coating provides high deposit rates consistent with out-of- position welding.
