OK Femax 33.80
SMAW
Type Rutile
OK Femax 33.80 is a high-speed, high-recovery, iron powder electrode giving a metal recovery of approx. 180%, particularly suitable for fillet welds. On alternating current an open circuit voltage of ²50 V is necessary. OK Femax 33.80 is very easy to strike and restrike and the slag is easy to remove. Also available in long length for gravity welding.
