Metal Recommended Shielding Gas Comments

Carbon Steel

Carbon Steel StarGold C-25  Small and large diameter cored wire; short circuiting and globular transfer; good alloy retention; quiet arc; good bead profile; low smoke, fume, and spatter
Carbon Steel Carbon Dioxide Small and large diameter cored wire; short circuiting and globular transfer; wide penetration profile; higher fume and spatter levels;  greater loss of alloying elements
Carbon Steel StarGold C-15 Only for wires formulated to work in high argon content gas blends; spray like transfer; excellent alloy retention; quiet arc; good bead profile; low smoke, fume and spatter 
Carbon Steel CO2 Deep penetration and fast travel speeds but with higher burnthrough potential and more spatter; high current mechanized welding

Stainless Steel

Stainless Steel StarGold C-25 Small diameter cored wire; spray transfer;  good bead profile; little smoke and spatter;  low fume;  clean welds
Stainless Steel Carbon Dioxide Short circuiting and globular transfer; increased penetration, higher fume levels
