Just found the booklet, Welding Technique - the Repair of Armour Plate in the Field, dated 1943.
The rods they describe are Austenitic, but it does state;
"if armour plate electrodes are not available welding may be attempted with ordinary 'stainless steel' electrodes of 18% Cr and 8% Ni type"
"All austeniitc armour plate electrodes should be operated on reverse polarity (ie. electrode positive = work negative) at approx the following values;
6 SWG rod size ; 120-180 amps
8 SWG ; 100-140 amps
10 SWG ; 80-100 amps "
Hope this is of help.
