Built for light to medium duty fabrication, this gun accepts wire sizes from 0.035 to 0.045 inches and features a three-layer conductor tube construction consisting of a copper tube, silicon-resin glass insulator, and metal jacket. The 15-foot power cable provides reliable wire feedability and terminates with a Lincoln-style rear connection. The standard 60-degree conductor tube swivels 360 degrees around the handle and can be removed and replaced without pulling the conduit. Installed by professional welders and fabricators, this gun is designed for demanding production and shop environments.\u003c\/p\u003e\u003cp\u003eThe 1047-1077 suits a wide range of applications including farm maintenance, garage repair, production fabrication, artistic metalwork, and general shop jobs. The Lincoln-style rear connection makes it a direct fit for compatible Lincoln wire feeders. The fully insulated Mig-Kwik front connection allows fast connect and disconnect at the wire feeder, reducing downtime during consumable changes. Its heavy-duty construction and field-repairable split-half handle case make it a practical choice for ongoing production use where uptime matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400 amp rating with 60% duty cycle at CO2 gas\u003c\/li\u003e\n\u003cli\u003eThree-layer conductor tube: copper tube, silicon-resin glass insulator, and metal jacket\u003c\/li\u003e\n\u003cli\u003e15-foot power cable with Lincoln-style rear connection\u003c\/li\u003e\n\u003cli\u003e60-degree conductor tube swivels 360 degrees and removes without disturbing the conduit\u003c\/li\u003e\n\u003cli\u003eFully insulated Mig-Kwik connection for quick feeder connect and disconnect\u003c\/li\u003e\n\u003cli\u003eSplit-half handle case enables field repair without additional connectors\u003c\/li\u003e\n\u003cli\u003eOval handle shape reduces operator fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Lincoln-style wire feeders.
