Abstract

Welding torch comprising a torch body incorporating in a tubular core a mechanism for gripping a refractory electrode projecting beyond the torch body, a gas duct between the electrode and a coaxial sleeve and mechanisms and devices for providing a circulation of cooling water in the torch body in the immediate vicinity of the gas distribution chamber and in thermal contact with sleeve made of a thermally conducting matl. and with the electrode gripping mechanism, is characterised in that the cooling fluid circulation appts. extends to the transverse level of the distribution chamber. Esp. for electric arc welding of thick strip in controlled atmos.
