Claim 1
Independent Claim
273 words
A combination welding torch apparatus, which is utilizable interchangeably for the performance of a gas shielding arc welding operation utilizing a non-consumable electrode, or an electric arc welding operation utilizing a consumable electrode, and which is connectable to a gas supply and an electric power supply, and which includes a torch body member including a head portion and an insulating cover which encases the head portion, wherein the improvement comprises: a. means for interconnecting an adapter to the torch body member head portion, comprising a hollow collar member which is connected to the torch head portion, and which includes an outer surface portion, an inner surface portion, outer threaded segments over a substantial portion of the outer surface portion, and inner threaded segments over a substantial portion of the inner surface portion; and b. means for adaptably retaining a consumable electrode in the torch body member head portion, comprising: 1. a hollow chuck member, for retaining the consumable electrode therein, which includes a forward portion having a front-opening slot therein, an enlarged central portion, central threaded segments over a substantial portion of the enlarged central portion, a rear portion, and rear threaded segments over a substantial portion of the rear portion; and 2. a hollow adapter member, for retaining therein the hollow chuck member and the consumable electrode, and for connecting the hollow chuck member and the consumable electrode to the interconnection means, which includes a forward cavity portion which is generally complementary in shape to the forward portion of the hollow chuck member, an enlarged rear cavity portion, and rear threaded portions over a substantial portion of the enlarged rear cavity portion.
