Electrode numbers...

[bomberz1qr20]

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.

7018= 70,000......all position.....what shield coat is made of(have to track down my chart to tell you what each # of shield coat is )

Thanks.

Yeah I understand most of it.

Ex: E7024 is 70,000 PSI flat/horiz - what's the 4 mean? I've used this with DCEP.

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)
