Mil-Mig 700 is a solid steel, copper cladded continuous wire that produces excellent appearing welds over a wide range of welding parameters. Mil-Mig 700 features a perfected manganese to silicon ratio making it suitable for welding over moderate amounts of rust and scale. It is designed for welding mild, low and medium carbon, and low alloy steels. Applications include: fabrication and repair of heavy equipment, farm implements, railcars, truck trailers, H and I beams, cold and hot rolled steels, and general welding. Mil-Mig 700 produces excellent mechanical properties even when the weld surface is less than ideal. Try our Mil-Tig 720 cut length wire for (GTAW) tig welding.


Mil-Mig 700 requires either 100% CO2 or to enhance the welding characteristics the use of 70%-80% Ar/balance CO2 will increase wetting action, lower penetration, and offer a smoother metal transfer. When using an Ar/CO2 mixture, voltage should be reduced by 1 to 1.5 volts. If a spray arc metal transfer is preferred, typically the voltage will need to be increased by 50% and the inches/minute doubled. For hardened and large, thick sections, preheat should be used to prevent the formation of harden (HAZ) heat-affected zones and eliminate tendencies toward quench cracking when cooling.
