Caution
① Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before use.
② Preheat at 200~300℃(392~572℉).
③ Adopt back step method or strike the arc on a small steel plate prepared for this particular
purpose because arc striking on the base metal is in danger of initiating cracking.
④ Pay attention not to exceed proper heat-input because excessive heat-input causes
deterioration of impact values of all weld metal.
Purpose
① Low alloy high tensile steels
Attribute
① Iron powder and low hydrogen type electrode (high efficiency)
② Good crack resistance
③ Good X-ray performance
④ Good impact value at -50°C
