• The Austarc 77 is a smooth running basic type of low hydrogen iron powder electrode used for all positional welding except vertical down.
• The arc is very quiet with little spatter and the welds are exceptionally smooth with excellent wash in at the toes of the weld, thus giving minimum undercut.
• This electrode is used where the highest restrained work pieces are fabricated for mining equipment, pressure vessels, heavy girders, earth moving plant, repair and maintenance etc.
