Use Guide
- Clean all oil, water, and surface contaminants from the joint area before welding.
- Use a shielding gas flow rate between 15 and 20 L/min for optimal protection and weld quality.
- For currents above 250 A, maintain a wire dry extension of 20–25 mm to ensure stable arc and consistent deposition.
- Follow the recommended current ranges for each diameter: 1.0 mm (F(H)-80–250 A, V(OH)-110–160 A), 1.2 mm (F(H)-100–350 A, V(OH)-120–180 A), 1.6 mm (F(H)-170–390 A)
How It Compares
AK-ER60A is a gas shielded wire with copper plating, designed for high deposition and stable arc in low alloy steel welding. It differs from solid wires without plating in its improved conductivity and reduced spatter. Compared to flux-cored wires, it produces cleaner welds with less fume and slag, but requires external shielding gas. It is not intended for use in low-hydrogen applications where basic flux-cored wires are preferred.
