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

High-Performance Low Alloy MIG Welding Wire

The Hobart Quantum Arc D2 is a premium .035-inch solid MIG welding wire designed for applications requiring higher strength than standard mild steel wires can provide. Classified as ER80S-D2 (and meeting ER90S-G standards), this wire is engineered with a specific alloy composition containing Manganese and Molybdenum. These alloying elements significantly enhance the mechanical properties of the weld deposit, providing superior tensile and yield strength suitable for welding carbon and low alloy steels. It is an excellent choice for industries where structural integrity and durability are paramount.

One of the standout features of Quantum Arc D2 is its ability to produce X-ray quality welds. The wire is manufactured with a high level of deoxidizers, which effectively scavenge impurities from the weld pool, resulting in deposits that are virtually free of porosity and slag. This makes it particularly effective for critical applications such as high-temperature service piping and pressure vessels. Despite its robust chemical makeup, the wire maintains a low silicon content and exhibits excellent wetting characteristics, ensuring a smooth bead profile and seamless tie-ins.

This 45 lb spool comes on a durable 12-inch steel reel, designed for industrial wire feeders. The wire features a high-quality copper coating that serves dual purposes: it enhances electrical conductivity for a stable arc and improves feedability by reducing friction within the liner and contact tip. Whether used with a 75% Argon / 25% CO2 gas mixture or 100% CO2, operators can expect consistent performance in both single and multiple pass applications. The Quantum Arc D2 meets ASME SFA 5.28 and AWS A5.28 specifications, certifying its reliability for code-compliant work.
