Spoolarc 75 is a copper-coated 1% nickel solid wire for carbon steel and low alloy welding applications using either the MIG/Gas Metal arc welding (GMAW) or submerged arc welding (SAW) processes. It produces a deposit that meets the weathering requirements of AWS D1.1 and D1.5 and is designed to weld weathering steels and/or where improved low temperature impact toughness is specified. Shielding gas choices for spoolarc 75 are Ar/CO2 mixtures containing a minimum of 75% Ar or the 98% Ar/2% O2. In the sawmode, it is typically used with a neutral flux such as ESAB OK Flux 429, 10.71 and 10.62. It is used for bridge and structural welding.
