Just got this wire in. Although we had a few casualties playing with the settings, for example the outer protective shield of the Speedglas helmet which melted, once we got the right combination of wire speed and voltage we started getting some real nice beads and penetration. Slag comes off very easily. You can weld vertical at a high deposition rate with no problem. This is one of the lower flux dual shield wires. Fumes were a lot more than solid wire but not terrible. Stuff runs HOT especially at higher wire travel speeds. We run 92/8 shielding gas. Seems like it's going to be a versatile wire for the shop.
From ESAB's site: "Dual Shield 70 Ultra Plus is an all-position wire that is uniquely designed to provide high deposition, outstanding all position performance and a fume emission rate approaching that of solid wires. (I would say they have a ways to go to approach the solid wire fume rate:) It is optimized for use with 90% Ar/10% CO2 shielding but works well with mixes ranging from 75% Ar/25% CO2 to 95% Ar/5% CO2. Among the outstanding features of Dual Shield 70 Ultra Plus are a very wide operating window, very high out of position deposition rates (vertical up and overhead at over 12 lb/hr), and welds that are virtually spatter free. Dual Shield 70 Ultra Plus may be used in a variety of applications including railcar, automotive, heavy equipment, and general structural steel fabrication. It is especially recommended in applications where reduction of welding fume is a priority."
