OK Femax 38.48
SMAW
Type Rutile-basic

OK Femax 38.48 is a high-recovery, iron powder, LMA electrode, which gives extremely smooth fillets of equal leg length and a very low emission of fume and spatter. It is very easy to weld and is especially well fitted for horizontal fillets with a leg length of 4-6.4 mm. OK Femax 38.48 is as easy to use as a rutile electrode but the weld metal quality corresponds to that of the basic electrodes. The slag is easy to remove. Also available in Fematic length.
