OVERVIEW

Achieve X-Ray Quality Welds with QuantumArc D2

Take your welding projects to the next level with the Hobart QuantumArc™ D2 .045" MIG wire. Designed for professional welders who demand reliability and strength, this ER80S-D2 / ER90S-G classified wire is a step above standard mild steel wires. If you are working on projects that require high tensile strength—such as trailer frames, crane booms, or heavy-duty construction equipment—this wire provides the mechanical properties necessary to ensure your welds hold up under stress. The 33 lb steel reel ensures you have ample material for large jobs, fitting securely on standard industrial wire feeders.

Welders will appreciate the excellent runability of the QuantumArc D2. The high-quality copper coating facilitates smooth feeding, minimizing drag in the liner and ensuring a stable, consistent arc. This is crucial when welding out of position or on long joints where arc interruptions can lead to defects. The wire's chemistry is formulated to be high in deoxidizers, which helps combat contaminants on the base metal and prevents porosity. The result is a clean, sound weld deposit that is virtually slag-free, saving you valuable time on cleanup and grinding. The "excellent wetting" characteristic means the bead lays down flat and washes in well at the edges, creating a professional-looking profile with minimal effort.

Versatility is another major benefit of this product. It performs exceptionally well with both mixed gas (75% Argon / 25% CO2) for a smoother arc and less spatter, or straight CO2 for deeper penetration and lower operating costs. It is specifically recommended for root passes on open butt joints, where its controlled fluidity helps bridge gaps and ensure complete fusion. Whether you are repairing agricultural equipment, building roll cages, or fabricating pressure piping, the Hobart QuantumArc D2 offers the performance and quality assurance you need to weld with confidence.

FAQ

It meets AWS A5.28 specifications for both ER90S-G and ER80S-D2 classifications, indicating its suitability for high-strength low alloy steel welding.

This wire is designed for use with 75% Argon / 25% CO2 mixtures or 100% CO2 shielding gas.

It is ideal for high-temperature service piping, construction equipment, trailers, cranes, and other high-tensile strength applications.

Yes, it is specifically recommended for root passes on open butt joints due to its excellent wetting characteristics.

This product comes on a 12-inch steel reel containing 33 lbs (approximately 15 kg) of wire.

QuantumArc D2 offers higher tensile and yield strength than standard ER70S-X wires and contains high levels of deoxidizers for porosity-free welds.

Like all mild and low alloy steel wires, it should be stored in a dry, low-humidity environment to prevent rusting of the copper coating.

It is designed for welding carbon and low alloy steels, producing X-ray quality welds.
