JIS Z3251 DF2A-300-B
Notes on Usage
Welding Positions:
1. Preheating is unnecessary, in general, in case of multi-layer welding
of low alloy steel and high carbon steel, preheat at about
150℃(302℉).
2. Adopt back step method or strike arc on al small steel plate prepared
for this particular purpose for preventing blow hole at the arc starting.
3. Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before
use.
