The 20-foot lead cable provides reliable wire feedability and connects via a Miller-style rear connection. The heavy-duty contact tip accommodates wire sizes from 0.045 to 1\/16 inches. The oval-shaped handle is balanced to pivot at its center, reducing operator fatigue during extended use. A 60-degree metal jacket conductor tube swivels a full 360 degrees around the handle for repositioning without disconnecting. Fully tested and field-repairable, this gun is built for semi-automatic welding in medium to heavy-duty fabrication environments.\u003c\/p\u003e\u003cp\u003eThe 1040-1127 is suited for production welding, maintenance and repair, and heavy fabrication in shop, farm, and industrial settings. The Mig-Kwik connection system allows quick hookup and disconnection at the wire feeder, reducing downtime between jobs. The steel spring strain relief at the rear of the handle supports the Cablehoz and minimizes wire feed issues over long production runs. Front-end consumables are interchangeable with the Tweco Spray Master series and Tweco Professional No. Series guns, which lowers inventory requirements for shops running multiple guns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e400A rating at 60% duty cycle with CO2 gas for medium to heavy-duty semi-automatic welding\u003c\/li\u003e\n\u003cli\u003e20-foot lead cable with Miller-style rear connection for direct feeder compatibility\u003c\/li\u003e\n\u003cli\u003e360-degree swivel on 60-degree metal jacket conductor tube for flexible positioning\u003c\/li\u003e\n\u003cli\u003eOval-shaped handle balanced at center pivot to reduce grip fatigue during long runs\u003c\/li\u003e\n\u003cli\u003eSilver-plated trigger contacts with self-cleaning action on each actuation\u003c\/li\u003e\n\u003cli\u003eThree-layer conductor tube construction: copper tube, silicon-resin glass insulator, metal jacket\u003c\/li\u003e\n\u003cli\u003eSplit-half handle case for field-repairable access to Cablehoz without additional connectors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFront-end consumables are interchangeable with the Tweco Spray Master series and Tweco Professional No. Series MIG guns.

Power down and de-energize the wire feeder before connecting or disconnecting the gun lead. Inspect the Cablehoz, conductor tube, and contact tip for wear before placing the gun in service. Do not operate the gun above its rated amperage or duty cycle, as doing so will shorten consumable life and may damage the cable assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 400A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Cycle\u003c\/strong\u003e: 60% with CO2 gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Length\u003c\/strong\u003e: 20 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size Range\u003c\/strong\u003e: 0.045 to 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Method\u003c\/strong\u003e: Air cooled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Tube Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Tube Swivel\u003c\/strong\u003e: 360 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Connection Style\u003c\/strong\u003e: Miller style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 23.2 x 14.5 x 3.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TWECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1040-1127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51342740291890,"sku":"1040-1127","price":1323.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545655.jpg?v=1782005259","url":"https:\/\/voomisupply.com\/products\/tweco-1040-1127-mig-gun-400a-20-ft-air-cooled","provider":"Voomi Supply","version":"1.0","type":"link"}
