PCT No. PCT/JP85/00417 Sec. 371 Date Dec. 11, 1985 Sec. 102(e) Date Dec. 11, 1985 PCT Filed Jul. 23, 1985 PCT Pub. No. WO86/00843 PCT Pub. Date Feb. 13, 1986.A nozzle for gas shielded arc welding having a support ring to be mounted on a welding torch, a cylindrical nozzle member to be mounted on the support ring and a holddown ring for securing the nozzle member to the support ring. The nozzle member is formed of a heat-resistant non-conductive material so that spatters seldom adhere to the nozzle member. The nozzle member is fixed by being pressed against the support ring, which structure facilitates the manufacture of the nozzle member. This is useful especially as a nozzle for CO2 arc welding.
