Claims

[Scope of utility model registration request]

A neck end fitting is installed on the outside of the wire supply tube placed in the center, and a contact tip is attached to the tip to form a shielding gas passage and a cooling water introduction/output passage, and a nozzle is installed on the outside of the base of this neck end fitting. Water cooling for welding comprising an insulator, and a water cooling nozzle having a cooling water passage formed inside the nozzle insulator, which is connected to the cooling water introduction/output passage of the neck end fitting through the nozzle insulator. In the torch, a plurality of sealing members are respectively disposed on the overlapping surface of the neck end fitting of the nozzle insulator and the water cooling nozzle, which are located on the distal side of the connection between the neck end fitting and the cooling water passage of the water cooling nozzle, and the nozzle insulator and the water cooling A water-cooled welding torch characterized by having a drain hole formed in a part of the nozzle other than the cooling water passage.
