LOGICAL FLUX CORED WIRE CHOICE: If most of your welds are made in the flat or horizontal weld positions on plate with "mill scale / rust issues" the first choice for flat / horizontal welds is the E70T-1 flux cored wires using straight CO2. 

When welding on plate >5/16, >8mm, the optimum E70T-1 wire size to attain good weld puddle control with maximum weld deposition rate potential is the 1/16 (1.6 mm) wire.Avoid the larger diameter E70T-1, 3/32 (2.4 mm) and larger wires as the high current requirements for optimum weld deposition rates, typically will not be attained.Note many weld shops use the fast freeze slag E71T-1, all position flux cored wires for the flat or horizontal weld positions, be warned these wires on these applications can result in severe porosity, slag inclusions, worm tracks, poor fusion and a pock marked weld surface.
