The Lincoln Electric SuperArc L-56 (ED561007) is a premium copper-coated mild steel solid wire designed for the Gas Metal Arc Welding (GMAW) process. Classified as ER70S-6, this .045-inch diameter wire is engineered with elevated levels of manganese and silicon. These deoxidizers make the L-56 exceptionally capable of handling base materials with medium to heavy mill scale, rust, or oil, ensuring sound welds even in less-than-perfect surface conditions.<\/p>\n
Packaged on a 44lb fibre spool, this product is optimized for industrial environments requiring consistent feedability and arc stability. The high-quality copper coating improves electrical conductivity and reduces friction in the liner, significantly extending contact tip life and minimizing downtime. The wire supports a wide range of metal transfer modes, including short-circuiting, globular, axial spray, and pulsed spray transfer, making it a versatile choice for various welding positions and parameters.<\/p>\n
Ideally suited for general fabrication, automotive assembly, and structural steel work, the SuperArc L-56 delivers excellent toe-wetting action, resulting in a flat, smooth bead profile that requires minimal post-weld grinding. Its consistent chemistry and diameter control ensure repeatable performance, critical for automated or high-volume manual welding operations.<\/p>\n","protected":false},"excerpt":{"rendered":"Lincoln Electric\u00ae SUPERARC\u00ae L-56\u00ae features high levels of manganese and silicon deoxidizers and tolerate medium to heavy mill scale surfaces.\n\nExcellent toe-wetting provides optimal bead appearance.\n\nCopper coated for long contact tip life.\nSupports short-circuiting, globular, axial spray and pulsed spray transfer.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1962,1959],"product_tag":[],"class_list":["post-1752583","product","type-product","status-publish","product_cat-steel-mig-and-tig-wires","product_cat-welding-wires-and-electrodes","pa_aws-spec-er70s-6","pa_brand-lincoln","pa_diameter-0-045-2","pa_diameter-0-045","pa_grade-s6-copper-coated","pa_grade-s6-copper-coated-2","pa_packaging-44lb-spool","pa_packaging-44lb-spool-2","pa_packaging-description-44lb-spool","pa_packaging-description-44lb-spool-3","pa_polarity-dc","pa_polarity-dcep","pa_spool-size-44lb","pa_weld-process-mig","pa_wire-type-solid","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
