MX-A70C6LF 80%Ar - 20%CO2 EN ISO 17632-A-T 42 3 M M 3 H5 AWS A5.18 E70C-6M Description and Application FAMILIARCTM MX-A70C6LF is a metal-cored wire for mild steel and 490MPa high tensile strength steel. This wire can be welded with less fume level in lower optimum voltage as well comparing with our conventional metal cored wire FAMILIARCTM MX-A100. That is the simple reason why this newly developed metal cored wire is named as “LF” which stands for “Low Fume”.
