Exothermic welding produces a connection with conductivity equal to or greater than the conductors being joined, making it a standard method for grounding and bonding applications. The 250 cartridge contains the weld metal charge required for a single weld shot and is designed for use within the Cadweld system of molds and accessories. Electrical contractors and grounding specialists are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThis welding material cartridge is suited for grounding electrode system (GES) installations, lightning protection bonding, and utility grounding work in both residential and commercial applications. It is used wherever a permanent, corrosion-resistant electrical bond is required between conductors or between a conductor and a grounding electrode such as a ground rod, structural steel, or water pipe. The F20 designation referenced in the product data indicates a specific weld metal formulation within the Cadweld system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExothermic weld process creates a permanent molecular bond between conductors\u003c\/li\u003e\n\u003cli\u003eF20 weld metal formulation for specified conductor and electrode combinations\u003c\/li\u003e\n\u003cli\u003eSingle-shot cartridge format for consistent, repeatable weld output\u003c\/li\u003e\n\u003cli\u003eNo external power source required - reaction is self-contained\u003c\/li\u003e\n\u003cli\u003eProduces a connection that resists corrosion and mechanical loosening over time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use within the Cadweld exothermic welding system, including compatible Cadweld graphite or semi-permanent molds rated for the F20 weld metal formulation and the 250 weld metal charge size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExothermic welding must be performed by a qualified electrician or grounding specialist following applicable NEC requirements for grounding and bonding. All conductors and mold surfaces must be clean and completely dry before initiating the weld reaction. Keep the weld area clear of flammable materials and use appropriate personal protective equipment including face shield and gloves. Never alter or repackage the weld cartridge, and follow the mold manufacturer's handling instructions for the specific mold type being used.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeld Metal Formulation\u003c\/strong\u003e: F20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeld Charge Size\u003c\/strong\u003e: 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CADWELD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NVENT","offers":[{"title":"Default Title","offer_id":68304990863666,"sku":"250","price":73.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/PH0129.jpg?v=1793737319","url":"https:\/\/voomisupply.com\/products\/cadweld-250-welding-material-cartridge-weld-system","provider":"Voomi Supply","version":"1.0","type":"link"}
