Description and Applications
Welding of mild steel for ships, machinery, structures, and bridges, and carbon steels of less than 35 mm thickness for boilers and pressure vessels.
 

Guideline in Usage

1. If coating flux absorbs excessive moisture, arc and slag fluidity become unstable, spatters increase, and undercuts and blowholes are apt to occur. Damp electrodes should be re-dried at 70 ∼ 120℃ for one hour.
2. Excessively high current and wide weaving deteriorate X-ray quality. Use optimum current and limit weaving width to within 2.5 times electrode diameter.
