OK Femax 39.50
SMAW
Type Acid

OK Femax 39.50 is a very fast, high-recovery, acid electrode for horizontal-vertical fillets, lap and butt joints in mild steels. The electrode gives a nice profile with a very good slag cover. The slag is porous and easy to deslag. Tolerates a wide range of bead run-out lengths.
