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.
Electrode used for cutting, bevelling and piercing works. Particularly suitable for cutting industrial metals like steels, cast irons, non-ferrous metals and also metals which are difficult or impossible to cut with oxyacetylene process. Suitable for cleaning faulty welding places and defective surfaces at high speed and in all positions. Electrode should be definitely not left to dry, but should contain certain amount of dampness. Possible to use in DCEN or DCEP. DCEN provides higher metal removal speed. 
Electrode especially used for all cutting, gouging, bevelling and piercing purposes. Particularly suitable for cutting industrial metals like steels, cast irons, non-ferrous metals and also metals which are difficult or impossible to cut with oxyacetylene process. Resulted surface finish is very clean and smooth. E CUT-S should be definetely not left to dry, but should contain certain amount of dampness. Possible to use in DCEN or DCEP. DCEN provides higher metal removal speed.
