Regarding covered electrodes; diameters not covered by the consumable classification standard shall be welded with 70 % to 90 % of the maximum welding current recommended by the manufacturer. Furthermore, the number of layers shall be adjusted to common welding practice as recommended. When qualification is for both direct current (d.c.) and alternating current (a.c.) operation then testing shall be carried out using alternating current (a.c.). When qualification is for d.c. operation with both polarities then the polarity recommended by the manufacturer shall be tested.
