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. To carry out welding a short arch, to smooth out edges before welding. Repeated calcination of electrodes before welding 340÷380 ºС during 2,0÷2,5 hours.
