Built from copper, this tip is part of Lincoln Electric's Copper Plus design, which uses a larger-diameter body to increase total copper content per tip. The added copper mass improves heat dissipation, keeping the tip cooler during extended welding cycles. It is rated for up to 550 amps, making it suitable for demanding MIG welding operations. The tip also features anti-seize threading to prevent the tip from fusing or seizing to the gun neck during high-heat use. Welding professionals and fabricators install this tip as a routine consumable replacement.\u003c\/p\u003e\u003cp\u003eThis contact tip is designed for use with the Magnum PRO MIG welding gun. It fits threaded contact tip seats and accepts 0.045-inch MIG wire. The Copper Plus design is well suited for high-amperage, high-duty-cycle environments such as production welding, structural fabrication, and heavy industrial MIG applications where tip longevity and consistent arc performance are priorities. It is sold individually and is intended for direct replacement during routine gun maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCopper Plus construction: larger-diameter body increases copper content for better heat dissipation\u003c\/li\u003e\n\u003cli\u003eAnti-seize threading prevents tip from seizing or fusing to the gun neck during high-heat operation\u003c\/li\u003e\n\u003cli\u003eRated for up to 550 amps for heavy-duty MIG welding applications\u003c\/li\u003e\n\u003cli\u003eAccepts 0.045-inch MIG wire diameter\u003c\/li\u003e\n\u003cli\u003eThreaded connection type for secure, repeatable installation\u003c\/li\u003e\n\u003cli\u003eCompatible with Magnum PRO MIG welding guns\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Lincoln Electric Magnum PRO MIG welding guns.

Always power down the welder and disconnect the gun from the power source before removing or installing a contact tip. Use the appropriate tip wrench to avoid damaging the tip or gun neck threads. Do not overtighten, as this can deform the tip seat or contribute to premature tip failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter (Min)\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter (Max)\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Amperage\u003c\/strong\u003e: 550 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage 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: LINCOLN ELECTRIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KP2745-045R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LINCOLN ELECTRIC","offers":[{"title":"Default Title","offer_id":51559505396018,"sku":"KP2745-045R","price":15.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9de1185bec67bce1cefb7855eb9e40af.jpg?v=1786434180","url":"https:\/\/voomisupply.com\/products\/lincoln-electric-kp2745-045r-mig-contact-tip-0-045-in-copper","provider":"Voomi Supply","version":"1.0","type":"link"}
