Supplied in a convenient <strong>5kg (11lb) spool<\/strong>, this wire is perfectly sized for portable MIG machines and smaller workshop setups where maneuverability and space are considerations. The ER70S-6 classification indicates a high content of deoxidizers, specifically manganese and silicon, which are essential for combating porosity when welding over mill scale, light rust, or oil.<\/p>\n<p>One of the standout characteristics of this Bonarc wire is its <strong>precision winding<\/strong>. Unlike random-wound spools that can snag or tangle, causing frustrating downtime and burn-backs, this wire is layer-wound to ensure smooth, uninterrupted feeding through the liner and contact tip. This results in a stable arc and consistent deposition rates, critical for achieving high-quality welds in production environments.<\/p>\n<p>The chemical composition is optimized to produce a highly fluid weld pool with excellent wetting properties. This ensures the weld metal ties in smoothly at the toes, reducing the risk of lack of fusion and creating a flat, aesthetically pleasing bead profile. Whether used with 100% CO2 for deep penetration or an Argon\/CO2 blend for reduced spatter and better cosmetics, this wire delivers reliable performance across a wide range of parameters.<\/p>\n<h3>Key Technical Benefits<\/h3>\n<ul>\n<li><strong>Enhanced Deoxidation:<\/strong> High silicon levels help scavenge impurities, making it more forgiving on base metals that aren&#8217;t perfectly clean.<\/li>\n<li><strong>Versatile Shielding Gas:<\/strong> Compatible with both straight CO2 and Argon-based mixtures, offering flexibility depending on the required penetration and bead appearance.<\/li>\n<li><strong>Mechanical Toughness:<\/strong> Provides excellent impact toughness even in low-temperature conditions, suitable for structural applications.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"Mild Steel wire for welding of mild steel and 490MPa tensile strength materials. \n\nCommon applications include HVAC duct work, structural application, heavy equipment fabrication and automotive parts fabrication.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1962,1959],"product_tag":[],"class_list":{"0":"post-1783962","1":"product","2":"type-product","3":"status-publish","5":"product_cat-steel-mig-and-tig-wires","6":"product_cat-welding-wires-and-electrodes","7":"pa_aws-spec-er70s-6","8":"pa_brand-bonarc","9":"pa_diameter-0-035","10":"pa_grade-s6-copper-coated","11":"pa_packaging-11lb-spool","12":"pa_packaging-5kg-spool","13":"pa_packaging-description-5kg-tube","14":"pa_polarity-dc","15":"pa_spool-size-5kg","16":"pa_weld-process-mig","17":"pa_wire-type-solid","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\/1783962","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=1783962"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_brand?post=1783962"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_cat?post=1783962"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_tag?post=1783962"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
