Rated at 60% duty cycle when operating with CO2 gas, this gun is built for demanding continuous-use environments. The one-piece impact-resistant handle accepts the trigger at the top or bottom position, giving the operator flexibility in torch orientation. A micro-switch trigger design with a metal paddle-style lever controls wire feed start and stop. Spare trigger leads are routed inside the cable assembly, and the replaceable conduit keeps maintenance straightforward. Licensed welding professionals and fabrication shops will find this gun ready for production-level workloads.\u003c\/p\u003e\u003cp\u003eThe SEFC 350 is suited for heavy industrial and structural welding applications including shipbuilding, offshore yard work, steel industry fabrication, automotive repair, and general maintenance welding. Its heavy-duty front-end consumables are interchangeable with other leading flux-cored guns, making it a practical drop-in replacement on job sites where standardized consumable inventory is a priority. The gun handles wire diameters from 0.030 inches to 0.035 inches, covering the most common self-shielded flux-cored wire sizes used in structural and repair welding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e350-amp output rated at 60% duty cycle with CO2 gas\u003c\/li\u003e\n\u003cli\u003eCompatible with 0.030 inch to 0.035 inch gasless flux-cored wire\u003c\/li\u003e\n\u003cli\u003eOne-piece impact-resistant handle with top or bottom trigger positioning\u003c\/li\u003e\n\u003cli\u003eMetal paddle-style micro-switch trigger for reliable wire feed control\u003c\/li\u003e\n\u003cli\u003eSpare trigger leads stored inside the cable assembly for fast field replacement\u003c\/li\u003e\n\u003cli\u003eReplaceable conduit and heavy-duty front-end consumables interchangeable with other leading flux-cored guns\u003c\/li\u003e\n\u003cli\u003eRugged power cable with proven abrasion and heat resistance for harsh shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with all self-shielded gasless flux-cored wires in the 0.030 inch to 0.035 inch diameter range.

Power down and disconnect the wire feeder before changing the conduit, consumables, or trigger leads. Verify that the liner and contact tip match the wire diameter in use before energizing the system. Follow applicable AWS and facility safety standards for MIG and flux-cored welding equipment connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 350 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Cycle\u003c\/strong\u003e: 60% at rated amperage with CO2 gas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter Range\u003c\/strong\u003e: 0.030 inches to 0.035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcess\u003c\/strong\u003e: Gasless flux-cored (FCAW-S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.95 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 24.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 16.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5.1 inches\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: 1031-1643\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51343122596146,"sku":"1031-1643","price":1140.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545618.jpg?v=1782017309","url":"https:\/\/voomisupply.com\/products\/tweco-1031-1643-flux-cored-mig-gun-350-amp-gasless","provider":"Voomi Supply","version":"1.0","type":"link"}
