TYPICAL APPLICATIONS
For welding fine-grained construction steels, heavy sections, and low alloy steels, High-pressure vessels, storage tanks, pipelines chemical industries.
WELDING PROCEDURE:
Use short arc length. Weaving of electrodes, if necessary should be done at slow speed and keeping a short arc. The electrodes should be used in perfectly dry condition. Redry electrodes at 300-350° C for one hour.
