Hobart 77TM is a metal-cored wire designed for high speed fillet and butt welding in the downhand position using Argon + 18-25% CO2 shielding gas mixture. Weld beads are almost completely slag free with only minimal silicon islands, reducing the time and effort spent between runs and on cleanup prior to surface finishing.
Hobart 77TM is recommended for single and multi pass welding in both flat and horizontal positions for mild steel, carbon and maganese carbon steels with minimum clean up and where high deposition rates and efficiencies are required in high productivity, semi automatic and fully automatic welding installations. Suitable applications include mining buckets, structural fabrication and tank construction where high speed welding is required.
