Electrode numbers...

admin

So I understand the "E". The 1st and 2nd digits in a 4 digit number and 1st, 2nd and 3rd in a 5 digit number mean tensile strength in ksi, the fourth is position, (1= all, 2 = flat/horiz, 3=flat only) So what does the last digit mean? Is there a way to tell? I've looked it up, but I can't find a "If you see this number it means this" type chart.

Reply:LAST DIGIT:0 = D.C.+ (Cellulose Sodium)1 = A.C. (Cellulose Potassium)2 = D.C.- (or A.C.) (Titania Sodium)3 = A.C. (or D.C. + or D.C.-) (Titania Potassium)4 = A.C. (or D.C.- or D.C.+) (Iron powder Titania)5 = D.C.+ (Low hydrogen sodium)6 = A.C. (or D.C.+) (Low hydrogen potassium)7 = A.C. (or D.C.+) (Iron powder, Iron oxide)8 = A.C. (or D.C.+) (Iron powder, Low hydrogen)I'll be the LAST one to let you down !
