Welding torch gas cup extension

摘要

A gas cup extension assembly (10) is mounted on a standard electric welding torch gas cup (11) to enable welding in areas with limited access. The gas cup assembly (10) has a tubular insert (14) that fits within the gas cup (11) but extends a lower externally threaded portion (17) downward through the gas cup exit opening. A tubular extension (18) is screwed onto the threaded portion (17) so as to be placed tight against the lower edge of the gas cup (11). The upper portion (20) of the extension has a rim (21) to define the outer perimeter of the seat edge about the entrance opening so a gasket (24) may be placed to effect an air tight seal between the tubular insert (14) and tubular extension (18). The tubular extension (18) will have its lower portion (19) shaped as desired for the particular welding activity and may easily be replaced with another extension having a different shaped lower portion.
