Applications One side welding of pipes and general butt joints of mild steel and 50kgf/mm2 class high
tensile strength steel.
Characteristics LH-28W is a low hydrogen type electrode for exclusive use for one side welding of pipes
and general structures.

Its arc stability is extremely good to perform one side welding with relatively low currents.

LH-28W provides good slag detachability and smooth weld beads.
Notes on usage (1) Dry the electrodes at 300~350℃ for 30~60 minutes before use.

(2) Strike the arc on a small steel plate prepared for this purpose or on the side wall of the groove.

(3) Keep the arc as short as possible.

(4) Reverse welds of good appearance is obtained with proper currents and optimum
root gaps (about 3mm).

(5) Stop the arc after moving the crater to the side wall to the groove.
