Spoolarc 75 is a MIG and submerged arc wire with 1% nickel content that meets the weathering requirements of AWS D1.1 and D1.5.
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. Spoolarc 75 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 SAW mode, Spoolarc 75 is typically used with a neutral flux such as ESAB OK Flux 429, 10.71, and 10.62. Spoolarac 75 is used for bridge and structural welding.
