Dual Shield 7100 LC provides outstanding operator appeal with its easily controlled arc, improved operation at lower current levels, minimal spatter and easily removed slag. Dual Shield 7100 LC can be used with CO2 or 75% Ar/25% CO2 shielding, however pure CO2 is recommended in applications where restraint is high.
