A TORCH BODY FOR CO2 WELDING MACHINE

The present invention relates to a torch body for a carbon dioxide welding machine which supplies gas supplied through a power cable to a nozzle by being applied to a carbon dioxide (CO2) welding machine and which reduces welding radiant heat from being transmitted to a user hand by separating a gas diffuser from a nozzle. The torch body of a carbon dioxide welding machine can safely supply and freely bend a welding rod and can uniformly maintain the welding rod to be bent when in use. The torch body of a carbon dioxide welding machine installed between the gas diffuser and the nozzle includes: a connecting protrusion which has a sphere shape to protrude from the rear side of an adapter coupled to the front of the nozzle; a connecting groove part which is concave forward of the gas diffuser; body members which connect, in a stepped manner, the connecting groove parts and the connecting protrusions which are formed on the front side and the rear side thereof so as to be coupled with the connecting protrusion of the adapter and the connecting groove part of the gas diffuser; an insulating tube covered on the outside of the body member; a rubber tube covered on the outside of the insulation tube; and a coil spring inserted into a through hole formed in the body members and the gas diffuser.
