The Lincoln Electric Magnum PRO Curve 400 Semi-Automatic MIG Gun (K2952-2)<\/strong> is engineered to meet the rigorous demands of high-production fabrication environments. Rated at 400 Amps at 60% duty cycle<\/strong> (using CO2), this air-cooled gun combines industrial-grade construction with advanced consumable technology to deliver consistent performance and reduced downtime. The 15-foot cable assembly provides ample reach for large weldments, making it an ideal choice for structural steel, heavy equipment manufacturing, and general fabrication.<\/p>\n At the core of the Magnum PRO series is the Copper Plus\u2122 contact tip system<\/strong>. These tips are designed with a larger diameter and greater mass than standard industry tips, significantly improving heat dissipation. This thermal efficiency keeps the tip cooler, preventing wire burn-back and extending the lifespan of the consumable. For industrial operators, this translates to fewer tip changes, lower inventory costs, and higher arc-on time.<\/p>\n Operator comfort is critical for weld quality and safety. The Magnum PRO Curve 400 features Lincoln\u2019s classic Curve\u2122 handle design<\/strong>, which is lightweight and balanced to fit naturally in the hand. The ergonomic grip reduces wrist strain and fatigue during extended welding sessions. Additionally, the gun features a rotating gun tube<\/strong> and a convenient gun hanger clip, allowing welders to adjust the torch orientation for optimal access to tight joints and comfortable positioning in out-of-position welds.<\/p>\n Maintenance is streamlined with the Magnum PRO series. The expendable parts\u2014including nozzles, diffusers, and tips\u2014are interchangeable across the 350A and 550A models, simplifying inventory management. The patent-pending anti-seize thread design on the tips and diffusers ensures that parts can be removed easily, even after high-heat applications. This gun comes ready to weld with a standard 0.045″ tip setup but supports a wide wire diameter range from 0.025″ to 5\/64″.<\/p>\n","protected":false},"excerpt":{"rendered":"Lincoln Electric\u00ae Magnum\u00ae PRO CURVE 400 Welding Gun 15 FT. \n\nIndustrial Grade ConstructionLincoln Electric Copper Plus\u00ae Contact Tips.\n\nLarger tip diameter and mass improve heat dissipation to increase tip life.\n\nOur curve handle design is lightweight and balanced, providing a comfortable grip to reduce fatigue.\n\nRotating Gun Tube and Gun Hanger Clip Allows any number of hand positions to reduce fatigue or fit into tight spaces. \n\nSimplified Expendable Parts Selection.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[2042,2043],"product_tag":[],"class_list":{"0":"post-1762350","1":"product","2":"type-product","3":"status-publish","5":"product_cat-mig-accessories","6":"product_cat-mig-guns","7":"pa_amps-400amp","8":"pa_back-end-lincoln","9":"pa_brand-lincoln","10":"pa_brand-magnum","11":"pa_duty-cycle-50-400a-mixed-gas","12":"pa_duty-cycle-60-400a-co2","13":"pa_front-end-magnum","14":"pa_length-15-ft","15":"pa_length-15-ft-2","16":"pa_packaging-description-1-of-each","17":"pa_wire-size-0-025-5-64-2","19":"first","20":"onbackorder","21":"taxable","22":"shipping-taxable","23":"purchasable","24":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product\/1762350","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/media?parent=1762350"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_brand?post=1762350"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_cat?post=1762350"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_tag?post=1762350"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Copper Plus\u2122 Contact Tip Technology<\/h3>\n
