OK Femax 38.65
SMAW
Type Zirconium-basic

OK Femax 38.65 is a high-recovery LMA electrode, which gives a weld metal of high quality and very low content of hydrogen. OK Femax 38.65 is designed for welding of ordinary and high strength ships plate A, D and E qualities. When using AC, an open circuit voltage of 65 V is necessary.
