Engineered with a higher content of silicon and manganese, this wire acts as a powerful deoxidizer, making it an excellent choice for welding on base metals that may have light rust, mill scale, or oil. The chemical composition ensures a highly fluid weld pool, resulting in excellent wetting action and a flat bead profile that requires minimal grinding. This specific alloy classification (ER70S-6) is the industry standard for structural steel fabrication, offering a perfect balance of tensile strength and ductility.<\/p>\n<p>One of the standout features of this Bonarc wire is its precision layer winding. Unlike random-wound spools that can snag or tangle during high-speed welding, this 5kg spool is meticulously wound to ensure smooth, uninterrupted feeding through the liner and contact tip. This consistency is critical for maintaining a stable arc and preventing burn-back, especially when working with the fine 0.023&#8243; diameter. The wire is copper-coated to improve electrical conductivity and protect against corrosion during storage, ensuring that the wire remains fresh and ready to weld even after periods of downtime.<\/p>\n<p>This 0.023-inch diameter variant is specifically optimized for low-amperage applications. It allows operators to maintain a stable short-circuit transfer mode, which is essential for welding thin-gauge materials without excessive heat input or distortion. Whether utilized in a small fabrication shop or a large industrial manufacturing environment, the Bonarc ER70S-6 delivers reliable mechanical properties, including high yield strength and impact toughness, meeting the rigorous demands of AWS A5.18 standards.<\/p>\n<p><strong>Key Technical Benefits:<\/strong><\/p>\n<ul>\n<li><strong>Superior Deoxidizing:<\/strong> High Mn\/Si levels combat porosity caused by surface contaminants.<\/li>\n<li><strong>Stable Arc Characteristics:<\/strong> Promotes a smooth, consistent arc with minimal spatter generation.<\/li>\n<li><strong>Versatile Shielding Gas Compatibility:<\/strong> Performs exceptionally well with 100% CO2 for deep penetration or Argon\/CO2 blends for a cleaner appearance and reduced spatter.<\/li>\n<li><strong>Optimized Packaging:<\/strong> The 5kg (11lb) spool size fits most compact and portable MIG welding machines, making it a versatile choice for field work and shop use alike.<\/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-1783959","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-0-023-2","10":"pa_diameter-0-023","11":"pa_grade-s6-copper-coated","12":"pa_grade-s6-copper-coated-2","13":"pa_packaging-11lb-spool","14":"pa_packaging-5kg-spool-2","15":"pa_packaging-description-5kg-tube","16":"pa_polarity-dc-2","17":"pa_polarity-dc","18":"pa_spool-size-11lb","19":"pa_spool-size-5kg","20":"pa_weld-process-mig","21":"pa_wire-type-solid","23":"first","24":"onbackorder","25":"taxable","26":"shipping-taxable","27":"purchasable","28":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product\/1783959","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=1783959"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_brand?post=1783959"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_cat?post=1783959"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_tag?post=1783959"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
