Description:

Austarc 18TC is an iron powder hydrogen controlled electrode used primarily on C-Mn and low alloy structural steels. The unique twin-coat design for 18 type low hydrogen electrode offers excellent AC arc stability and superb DC+ arc transfer, excellent re-strike, reduced spatter level and extraordinary ease of use for out-of-position welding.

Typical Applications

Typical applications include oil and gas, pipe welding, structural steel construction, off-shore where Ni-alloying is prohibited, mining equipment, heavy girders and earth moving plant repair and maintenance.
