S307212-011 - Hobart Quantum Arc D2 ER80S-D2 .045" MIG Wire (600lb Drum)

Reliable Strength for Heavy Fabrication

When your welding project demands more strength than a standard ER70S-6 wire can provide, the Hobart Quantum Arc D2 .045" MIG wire is the professional's choice. Built for heavy-duty fabrication, this wire delivers high-strength deposits suitable for critical structural work, heavy equipment repair, and pressure vessel fabrication. The "D2" classification indicates a Manganese-Molybdenum alloy system, which boosts the tensile strength of the weld metal to approximately 100,000 psi, ensuring your welds can withstand extreme loads, dynamic stresses, and harsh operating environments. It is the go-to filler metal for welding ASTM A514, A517, and other high-yield steels.

Welders will appreciate the smooth, stable arc and low spatter levels characteristic of the Quantum Arc series. The wire wets out evenly, creating a flat bead profile that requires minimal post-weld grinding, saving you valuable time on cleanup. Its powerful deoxidizers help combat porosity, even when welding on base metals that aren't perfectly clean or have light rust. Whether you are welding thick-wall pipe, trailer frames, or earthmoving equipment, this wire provides the confidence that comes with X-ray quality integrity. The copper coating not only improves shelf life but also enhances electrical pickup at the contact tip, leading to a more consistent arc start and fewer burn-backs.

This configuration comes in a 600 lb Robo Pak, designed for shops that burn serious wire. If you are running continuous operations or automated welding systems, this bulk drum format is essential for maximizing efficiency. It eliminates the frequent interruptions of swapping out small spools, keeping your production line moving. The payout system of the Robo Pak is engineered to prevent tangles and wire flipping, ensuring a smooth, low-drag feed even over long conduit runs. Combined with Hobart's reputation for quality manufacturing, the Quantum Arc D2 ensures consistent wire diameter and cast, preventing feed jams and ensuring a steady electrical contact for flawless welds every time.
