Purpose
① General fabrication
Attribute
① Suitable for butt and fillet welding of thin plates ② Good restriking
② Good bead appearance
③ Easy to remove slag
④ Smooth arc and low fume
⑤ AC welding with low ocv
Caution
① Dry the electrodes at 70~100℃(158~212℉) for 30~60 minutes before use.
② Pay attention not to exceed the recommended range of currents.
Purpose
① Suitable for butt and fillet welding of thin plates
② Good restriking properties and high welding efficiency
③ Suitable for tack welding
④ Good mechanical properties
Attribute
① S-4303.T is a lime-titania type electrode used for welding in all positions. Iron powder contained in
the coating ensures both good restriking properties and high welding efficiency.
② It is suitable for tack welding and intermittent welding.
③ Mechanical properties of all-weld metal are also good.
Caution
① Dry the electrodes at 70~100℃ (158~212℉ ) for 30~60 minutes before use.
② As arc-restriking properties are not so good, it is suitable for intermittent welding.
Purpose
