Notes on Usage
Welding Positions:
① Dry the electrodes at 350~400℃ (662~752℉) for 60 minutes before use.
② Keep the arc as short as possible, and avoid large width of weaving.
③ Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blow hole at the arc starting.
Applications
AWS A5.1 / ASME SFA5.1 E7018-1 H4R can be used for welding of high tensile steel, such as bridges, buildings, rolling stock and low temperature used for steel structure.
