Welding electrodes CCH-4 4,0х450, 3 kg
Classification

GOST 9466-75 |
: CCH-4-Ø |
Purpose and scope
Electrodes of the CCH-4 brand are intended for cold welding, repair surfacing and welding of casting defects in parts of gray, high-strength and malleable cast irons, as well as welding of such cast irons with steel. Surfacing of the first one or two layers on worn-out cast-iron parts for subsequent surfacing with special electrodes. Welding in the lower position of the seam with direct current of reverse polarity (with a high open circuit voltage of the welding transformer and a short length of welding cables, welding with alternating current is possible).
