Applications Butt and fillet welding of carbon steel for pressure vessels, tubes, ships. Characteristics on Usage 1. Use welding grade Ar 100% gas. 2. All position welding and steel sheet welding can be performed quite easily. 3. Most suitable for one- side welding of tubes.

Applications Butt and fillet welding of steel structures such as vehicles, machinery and bridges. Characteristics on Usage SM-70 is a solid wire designed for all position welding by short-circuiting type transfer. As the deposition efficiency is high and penetration is deep, highly efficient welding can be performed. Notes on Usage 1. Use with CO 2 /Argon+15~25% CO 2 gas. 2. The Flow of quantity of shielding gas should be approximately 25 Q/min. 3. Use wind screen against wind. 4. Keep distance between tip and base metal 6~15mm for less than 250A, and 15~25mm for more than 250A of welding current.

Applications S-6013.LF can be used for welding of machinery, vehicles and light structural steels, and surface dressing of heavy steel structures. Characteristics on Usage S-6013.LF is a low fume, high titania type electrode. Fume generation is about 20% less than conventional high titania type electrodes and whose usability is excellent in all position welding. S-6013.LF is suitable for welding of light structural steels because of its stable arc, shallow penetration and smooth welding bead. Notes on Usage 1. Dry the electrodes at 70~100 o C(158~212 o F) for 30~60 minutes before use. 2. Pay attention not to exceed the range of proper currents.

Flux cored welding wire for all position welding with CO??. Compared with solid wire, spatter loss is low, bead appearance is beautiful and arc is soft with good stability. Slag covering is uniform with good removal.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.

Flux core wire can be used for welding of 2.25%Cr-1.0%Mo steel used for super heat tubes and steam pipes of boilers for electric power plant and marine use, equipment for oil refining industries and high temperature synthetic chemical industries. SC-91B3 is a titania type flux cored wire for all position welding. Arc stability is excellent. Spatter loss is low and slag covering is uniform with good removability.

Applications All position welding of building, shipbuilding, bridges, machinery and vehicles. Characteristics on Usage SF-71 is a titania type flux cored wire for all position welding with CO??. Compared with solid wire, spatter loss is low, bead appearance is beautiful and arc is soft with good stability. Slag covering is uniform with good removal. 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% CO 2 gas.
