It accommodates wire sizes up to 1\/16 inches and ships with a 12-foot lead cable that uses a Tweco-style rear connection for reliable wire feedability. The air-cooled design delivers a 60% duty cycle when run with CO2 gas. A 60-degree metal jacket conductor tube swivels a full 360 degrees around the handle, and the three-layer conductor tube construction — copper tube, silicon-resin glass insulator, and metal jacket — provides a consistent current path to the contact tip. Licensed welding technicians and industrial fabricators install this gun in production and maintenance settings.\u003c\/p\u003e\n\u003cp\u003eThis gun is suited for a wide range of applications including shop fabrication, production welding, maintenance and repair, and light industrial work such as farm and garage environments. The oval-shaped handle is balanced to pivot at its center, reducing operator fatigue across extended welding sessions. The Mig-Kwik connection allows quick hookup and disconnection at the wire feeder. Front-end consumables are interchangeable with the Tweco Spray Master series and other Tweco Professional No. Series guns, which reduces inventory requirements for shops running multiple guns.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400A rating with 60% duty cycle at CO2 gas for medium to heavy-duty fabrication\u003c\/li\u003e\n  \u003cli\u003eAccommodates wire up to 1\/16 inches with 12-foot Tweco-style rear-connection lead cable\u003c\/li\u003e\n  \u003cli\u003e60-degree metal jacket conductor tube swivels 360 degrees for positioning flexibility\u003c\/li\u003e\n  \u003cli\u003eSilver-plated trigger contacts with self-cleaning action on every actuation\u003c\/li\u003e\n  \u003cli\u003eSteel spring strain relief supports the Cablehoz at the rear of the handle to minimize wire feed issues\u003c\/li\u003e\n  \u003cli\u003eSplit-half handle case allows field repair without additional connectors\u003c\/li\u003e\n  \u003cli\u003eGun hanger at the bottom for safe, easy resting when not in use\u003c\/li\u003e\n  \u003cli\u003eHigh-impact crush-resistant handle made from special plastic composition for industrial durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eFront-end consumables are interchangeable with the Tweco Spray Master series and Tweco Professional No. Series guns.

Disconnect and de-energize the wire feeder before connecting or disconnecting the gun at the feeder connection. Verify that the conductor tube and Cablehoz are secured with both ball-point screws before initiating a weld. Do not exceed the rated 400A output or the specified duty cycle to avoid heat damage to the gun or cable assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 400A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Cycle\u003c\/strong\u003e: 60% at CO2 gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Cable Length\u003c\/strong\u003e: 12 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Wire Size\u003c\/strong\u003e: 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\u003eConnection Type\u003c\/strong\u003e: Tweco-style rear connection with Mig-Kwik feeder connection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 10.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 23.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1040-1112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346344640818,"sku":"1040-1112","price":1029.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545664.jpg?v=1782077976","url":"https:\/\/voomisupply.com\/products\/tweco-1040-1112-mig-gun-400a-12-ft-air-cooled","provider":"Voomi Supply","version":"1.0","type":"link"}
