This consumable component fits between the nozzle and the gun body, providing electrical isolation and protecting the contact tip holder from spatter and heat damage. Proper insulator condition is critical to maintaining arc stability and preventing short circuits caused by conductive spatter bridging internal gun components. Licensed welders, fabricators, and MIG welding technicians install this part as a routine consumable replacement during gun maintenance cycles.\u003c\/p\u003e\n\u003cp\u003eThis insulator is suited for MIG welding applications where Tweco No. 4 style guns are in service. Its slip-on design allows fast field replacement without special tooling, making it practical for production welding environments and service shops alike. It is sold individually as a single unit; minimum order quantity is 25 pieces, making it appropriate for stocking as a shop consumable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-on design allows quick replacement during routine gun maintenance\u003c\/li\u003e\n  \u003cli\u003eCompatible with Tweco No. 4 MIG guns rated up to 400 amps\u003c\/li\u003e\n  \u003cli\u003eProvides electrical isolation between nozzle and gun body\u003c\/li\u003e\n  \u003cli\u003eProtects internal gun components from spatter accumulation\u003c\/li\u003e\n  \u003cli\u003eSold in minimum quantities of 25 — suitable for shop stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Tweco No. 4 MIG guns rated up to 400 amps.

Disconnect the gun from the wire feeder and ensure the power source is off before servicing any gun components. Slide the worn insulator off the contact tip holder and press the replacement insulator firmly into its seated position before reinstalling the nozzle. Inspect mating surfaces for spatter buildup and clear before assembly to ensure a proper fit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 400 amps maximum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 1340-1100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346646532402,"sku":"1340-1100","price":125.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546101.jpg?v=1782086555","url":"https:\/\/voomisupply.com\/products\/tweco-1340-1100-nozzle-insulator-400a-mig-gun","provider":"Voomi Supply","version":"1.0","type":"link"}
