All position welding in shipbuilding, machinery, bridges, buildings, vehicles using mild and higher
strength steels.
Characteristics on Usage
 is the most widely used titania type flux cored wire for all position welding with CO₂
shielding gas. As deposition rate is higher than solid wire and manual metal arc electrode, highly
efficient welding can be performed.
Arc stability is excellent. Spatter loss is low and slag covering is uniform with good removability.
Fume generation is lower than conventional flux cored wires.
SF-71LF is effective for use in insufficient ventilation areas.

DC +                                                CO₂
Notes on Usage
① Proper preheating(50~150°C)(122~302°F) and interpass temperature must be used in order to
release hydrogen which may cause cracking in weld metal when electrodes are used for
medium and heavy plates.
② One-side welding defects such as hot cracking may occur with wrong welding parameter such
as high welding speed.
③ Use 100% CO₂gas.
