Recommendations - Electrodes provide high resistance of metal of a seam to formation of a time when lengthening an arch, allow to carry out welding in narrow cutting with the general bevel angle of edges not less than 150. To carry out welding a short arch, to smooth out edges before welding. Repeated calcination of electrodes before welding 380÷420 ºС during 1,0÷1,5 hour.
