FIELD: production processes. ^ SUBSTANCE: invention can be used for welding in space-limited environment. The proposed torch comprises a casing, nozzle, collet chuck, nonconsumable electrode, gas lens, cooling water and protective gas pipes arranged in the same horizontal pane. The casing is formed by the cooling water pipe circular loop. The loop lower side accommodates a bush attached thereto long with the collet chuck and nozzle, while the plug is mounted on the loop upper part. To add to the torch efficiency, cooling water feed and discharge pipe may have various cross sections. ^ EFFECT: expanded performances due to possibility of use in space-limited environment. ^ 2 dwg |
