Applications
All position welding of building, shipbuilding, bridge construction machinery and vehicles.
Characteristics on Usage
is a titania type flux cored wire for all position welding. It has extra low hydrogen
level(H5) and provides an exceptionally smooth and stable arc with a fast freezing slag system.
Welding Position Current Shielding Gas
DC + Ar + 20~25% 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 Ar + 20~25% CO₂gas.
