High-Performance CO2 Welding Wires | Durable & Low-Spatter for Industrial Use

Description For High-Performance CO2 Welding Wires:

CO2 welding isn’t just about speed—it’s about precision. Our wires are the go-to choice for workshops battling thick steel, rusty surfaces, or tight deadlines. From Chinese shipyards welding 20mm hull plates to Mexican auto plants assembling truck frames, these wires deliver clean arcs, minimal fumes, and X-ray-quality welds. Forget birdnesting or porosity; we’ve engineered these spools to feed like butter, even in 30-year-old MIG machines.

Specification For High-Performance CO2 Welding Wires:

High Performance CO2 Welding Wires Si 0.80-1.15% 22-28% Elongation Rate ISO 6892-1 tested at 20°C

Grades & Applications:
ER70S-6: All-rounder for carbon steel. Used to weld 10,000+ excavator buckets in South Africa.
ER70S-3: Lower silicon for cleaner welds on galvanized steel.
ER50S-6: For lower heat input on thin sheets (0.6-3mm).
Technical Parameters:
Diameter: 0.8mm (thin sheets), 1.0mm (general use), 1.2mm/1.6mm (heavy plate).
Spool Sizes: 5kg (portable), 15kg (high-volume), 300mm plastic/core.
Tensile Strength: 500-620 MPa (tested per AWS A5.18).
Elongation: 22-28% (3x better than cheap imports).
