It may weld to the inner surface of the nozzle or the chip, or it may enter and accumulate in the space between the broken nozzle inner surface and the chip, narrowing the shielding gas passage, preventing the shielding gas from flowing sufficiently, or disrupting the gas flow. The shielding of the welded part becomes incomplete, causing welding defects. Therefore, the nozzles are regularly removed for cleaning or replacement.

るＭＡＧ溶接、 ＭＩ（。The degree of spatter welding on the nozzle tends to be difficult as the temperature of the nozzle is lower. Therefore, in CO2 welding using CO2 gas as the shielding gas, the welding area of the nozzle is water-cooled for torches with a welding current of more than 350 mm. , MAG welding, which indirectly cools the nozzle but uses HR gas as the shielding gas, MI (.

ある。1. In welding, the radiant heat of the arc is strong, so even under the same welding conditions as C02 welding, the nozzle is heated to a greater degree, and indirect cooling of the nozzle does not cool it enough, so cooling water is applied to the nozzle itself. It is common to provide a passage for direct cooling. The present invention relates to an improvement of a nozzle water-cooled welding torch used for dog current CO2 welding, MAG welding using Ar as a shielding gas, and MIG welding.

Take the insulating cylinder provided with Il′N1
In addition, a nozzle provided with a cooling waterway communicating from the water supply side valve mechanism of the insulating tube to the drain side valve mechanism is removably attached to the insulating tube. With this configuration, when the nozzle is removed, the water supply side passage and the drainage side passage are closed by the water supply side valve mechanism and the drainage side valve mechanism, and the cooling water does not flow out.
