Lincoln suggests using a flux cored wire 0.045 inch(Insershield NR-211-MP) for 1/4 inch mild steel using a D2 setting(29 volts and 120 in/m feed). They state in their manual that this is close to using stick welding. They state that this gives better penitration than any other set-up with this welder.
Why is this? and why not use a solid 0.045 wire with gas. Why don't they go to the E (34volt) setting? Home Depot doesn't even carry this wire nor the tips.
Thanks Steve
