Electrode used for gouging and piercing works. Suitable for cleaning faulty welding places, defective surfaces and back-gouging on steels, cast iron, non-ferrous metals. The depth of the groove cut at one gouging should not exceed the diameter of the electrode. For cutting deep gouges the operation should be repeated several times. Electrode should be definitely not left to dry, but should contain certain amount of dampness. Prefered to use in DCEN due to it's higher metal speed.
