Applications and Features

( 1 ) Designed for welding root pass of pipeline with DC polarity.

( 2 ) Strong arc force, deep penetration, fast-freeze slag and good weldability.

( 3 ) Typical applications are high pressure pipes, oil tanks, boilers and outdoor welding.

Welding position

Welding Instruction

( 1 ) Do not over dry the electrode or operate under high current, which can cause early decomposition of the coating and affect the welding performance.

( 2 ) Please refer to Appendix A
