Rated at 550 amps at 100 percent duty cycle with CO2 shielding gas and 500 amps at 100 percent duty cycle with mixed gas, this gun delivers sustained output without thermal shutdown. The 12-foot cable length provides reach across larger workpieces and fixtures. Advanced dual cooling channels in the conductor tube accelerate heat dissipation, extending front-end consumable life up to five times longer compared to standard gas-cooled guns. Licensed welding professionals and heavy fabrication shops are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThe 1044-1126 is built for heavy-duty fabrication applications including shipbuilding, offshore yard work, tank and vessel fabrication, general manufacturing, automotive body work, and aerospace component welding. The ergonomic handle reduces operator fatigue during extended passes. The thick conductor tube adds mechanical durability and reduces the risk of damage from accidental drops. Wire diameter compatibility spans 0.035 inches to 1\/16 inch, covering a broad range of solid and flux-cored wire selections. The gun adapts to most competitive wire feeder platforms, making it a practical retrofit choice on existing weld cells.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated 550 amps at 100 percent duty cycle with CO2 and 500 amps with mixed gas\u003c\/li\u003e\n\u003cli\u003eDual cooling channels in the conductor tube for rapid heat dissipation\u003c\/li\u003e\n\u003cli\u003eConsumable life up to 5 times longer than gas-cooled alternatives\u003c\/li\u003e\n\u003cli\u003eAccepts wire diameters from 0.035 inches to 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e12-foot cable length for extended reach in fabrication environments\u003c\/li\u003e\n\u003cli\u003eErgonomic handle design reduces operator fatigue on long-duration welds\u003c\/li\u003e\n\u003cli\u003eCompatible with most competitive wire feeders for flexible integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a water-cooled OEM-style MIG gun for heavy-duty fabrication welding systems.

Disconnect and de-energize the welding power source and shut off the water-cooling supply before connecting or servicing the gun. Verify that the water inlet and outlet connections are leak-free and that flow rate meets the manufacturer minimum before energizing. Consult applicable facility safety codes and the wire feeder manufacturer guidelines for proper cable routing and strain relief.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating (CO2)\u003c\/strong\u003e: 550 A at 100 percent duty cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating (Mixed Gas)\u003c\/strong\u003e: 500 A at 100 percent duty cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Length\u003c\/strong\u003e: 12 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter Range\u003c\/strong\u003e: 0.035 inches to 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Type\u003c\/strong\u003e: Water-cooled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 9.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 20.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 15.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662067228027\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: 1044-1126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346448744754,"sku":"1044-1126","price":1605.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545679.jpg?v=1782080624","url":"https:\/\/voomisupply.com\/products\/tweco-1044-1126-water-cooled-mig-gun-550a-12-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
