The Bonarc ER70S-6 .023″ Steel Solid MIG Wire is a premium choice for industrial fabricators and manufacturing environments requiring consistent performance on mild steel. Supplied in a substantial 15kg (33lb) spool, this wire is engineered to maximize productivity by reducing downtime associated with frequent spool changes. The ER70S-6 classification indicates a chemical composition rich in deoxidizers, specifically manganese and silicon. These elements are crucial for industrial applications where base materials may not be perfectly clean; they effectively scavenge impurities, allowing for sound welds even over light rust and mill scale.<\/p>\n
One of the standout characteristics of this Bonarc wire is its excellent wetting properties. The high silicon content creates a highly fluid weld pool that ties into the toes of the weld smoothly, creating a flat bead profile that requires minimal grinding. This is particularly advantageous in high-volume production settings where post-weld finishing represents a significant cost. Furthermore, the wire is manufactured with tight diameter tolerances and a high-quality copper coating, which enhances electrical conductivity and protects the wire from corrosion during storage.<\/p>\n
Reliability in wire feeding is paramount for automated and semi-automated processes. This 15kg spool features precision layer winding, which ensures the wire pays off smoothly without snagging or tangling. This consistent feedability results in a stable arc and uniform penetration, essential for maintaining structural integrity in critical components. Whether used with 100% CO2 for deep penetration or an Argon\/CO2 blend for a smoother arc, the Bonarc ER70S-6 delivers professional results across a wide range of operating parameters.<\/p>\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-1783963","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","10":"pa_grade-s6-copper-coated","11":"pa_packaging-15kg-spool","12":"pa_packaging-33lb-spool","13":"pa_packaging-description-15kg-spool","14":"pa_polarity-dc","15":"pa_spool-size-15kg","16":"pa_spool-size-33lb","17":"pa_weld-process-mig","18":"pa_wire-type-solid","20":"first","21":"instock","22":"taxable","23":"shipping-taxable","24":"purchasable","25":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product\/1783963","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=1783963"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_brand?post=1783963"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_cat?post=1783963"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_tag?post=1783963"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
