Rated at 550 amps at 100% duty cycle with CO2 shielding gas and 500 amps at 100% duty cycle with mixed gas, this gun delivers sustained output without thermal throttling. The 12-foot cable length gives welders room to maneuver around large weldments. Advanced cooling channels built into the conductor tube accelerate heat dissipation, extending front-end consumable life up to five times longer compared to standard gas-cooled MIG guns. Licensed welding professionals and fabrication shops running heavy production schedules are the primary end users.\u003c\/p\u003e\n\u003cp\u003eThe Fusion Pro 9W is suited for heavy-duty fabrication environments where heat buildup and consumable wear are ongoing concerns. Typical applications include shipbuilding and offshore yard fabrication, tank and vessel construction, general manufacturing, automotive body fabrication, and aerospace component welding. The Euro-Kwik connection style allows the gun to adapt with most competitive wire feeders without additional adapters, making it a practical choice when standardizing a shop floor across multiple machines. Wire diameter compatibility runs from 0.035 inches through 1\/16 inch, covering a broad range of filler metal sizes common in structural and manufacturing applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e550 A at 100% duty cycle with CO2; 500 A at 100% duty cycle with mixed gas\u003c\/li\u003e\n  \u003cli\u003eWater-cooled conductor tube with advanced dual cooling channels for rapid heat dissipation\u003c\/li\u003e\n  \u003cli\u003eFront-end consumable life up to 5x longer than gas-cooled MIG guns\u003c\/li\u003e\n  \u003cli\u003eEuro-Kwik connection compatible with most competitive wire feeders\u003c\/li\u003e\n  \u003cli\u003eWire diameter range: 0.035 inches to 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003eErgonomic, easy-grip handle designed to reduce operator fatigue during extended use\u003c\/li\u003e\n  \u003cli\u003eThick conductor tube construction reduces risk of damage from accidental drops\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe Euro-Kwik connection style adapts with most competitive wire feeders.

Before connecting or disconnecting the gun, shut off the welding power source and depressurize the water-cooling circuit to prevent burns or coolant spills. Verify coolant flow rate and water-in and water-out connections are properly seated and leak-free before resuming operation. Follow the welding machine manufacturer guidelines and applicable workplace safety codes when integrating this gun into an existing setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 550 A at 100% duty cycle (CO2); 500 A at 100% duty cycle (mixed gas)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Length\u003c\/strong\u003e: 12 ft\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\u003eConnection Type\u003c\/strong\u003e: Euro-Kwik\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling Method\u003c\/strong\u003e: Water-cooled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 15.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662067228140\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: 1044-1138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51347675676978,"sku":"1044-1138","price":1605.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545752.jpg?v=1782111188","url":"https:\/\/voomisupply.com\/products\/tweco-1044-1138-water-cooled-mig-gun-550a-12-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
