S307208-045 - Hobart Quantum Arc D2 .035" MIG Wire ER80S-D2 45lb Steel Reel

Reliable Strength for Heavy-Duty Fabrication

When your welding project demands more strength than a standard ER70S-6 wire can offer, the Hobart Quantum Arc D2 .035" MIG wire is the professional's choice. This ER80S-D2 wire is specifically formulated for welding high-strength, low-alloy steels found in heavy construction equipment, trailers, cranes, and railcars. If you are repairing boom arms, fabricating structural frames, or welding high-pressure piping, this wire delivers the mechanical properties needed to ensure the weld holds up under extreme stress and service conditions.

Welders will appreciate the smooth runnability of Quantum Arc D2. The copper-coated surface ensures the wire feeds smoothly through your gun without drag or chatter, reducing downtime caused by bird-nesting or contact tip burn-back. The arc stability is excellent, providing good puddle control and wetting action that makes achieving a flat, professional-looking bead easier. It is versatile enough to be used for root passes on open butt joints as well as fill and cap passes on thick sections. The wire produces minimal slag, which means less post-weld cleanup and grinding for you.

Packaged on a heavy-duty 45 lb steel reel, this product is built for shop environments where high-volume welding is the norm. It performs exceptionally well with 75/25 Argon/CO2 mixed gas for reduced spatter and better arc control, but also runs effectively on straight CO2 for deeper penetration. By choosing Quantum Arc D2, you are upgrading your capabilities to handle high-tensile steels with confidence, knowing you are laying down X-ray quality metal that is free from porosity and defects.
