<p>Disclosed herein is a C02 welding torch. The torch is constructed so that an end of the torch is formed to allow compressed air or blown air to enter the torch, from separate resources and a power cable includes at a center thereof a gas pipe to feed C02 gas, a conductor and a control wire that supply electricity and cover the gas pipe, a hollow layer for air passage, and an outer coverage to cover a braid layer. Further, a cooling nozzle is constructed to allow air fed through the hollow layer of the power cable to be exhausted through an air guide pipe of the nozzle. Thus, when welding is performed, air passes through the power cable to cool the power cable, and passes through the air guide pipe to cool the front portion of the torch.</p> |
