S307212-028 - Hobart Quantum Arc D2 ER80S-D2 MIG Wire .045 60lb Spool

Reliable Performance for Tough Welds

When your project demands more strength than a standard ER70S-6 wire can deliver, the Hobart Quantum Arc D2 is your go-to solution. This .045-inch MIG wire is built for welders who need to lay down serious metal on high-strength steels without fighting the arc. The "D2" classification means it's alloyed with manganese and molybdenum, giving your welds that extra backbone needed for heavy-duty repairs on excavators, cranes, and trailers. It’s the wire you grab when the weld simply cannot fail.

Welders will appreciate the smooth feedability of the Quantum Arc D2. The high-quality copper coating prevents rust on the spool and ensures the wire glides through your liner and contact tip without dragging or bird-nesting. Once the arc is lit, you'll notice a crisp, stable puddle that wets out nicely, even on slightly difficult joints. Whether you are running a root pass on an open butt joint or filling a heavy groove, this wire gives you control. It produces a bead profile that is clean and uniform, minimizing the amount of post-weld grinding needed to make things look professional.

Flexibility is key in the shop, and this wire delivers by running well on both mixed gas and straight CO2. If you want that buttery smooth spray transfer feel, hook up the 75/25 mix. If you need to dig deep on thick plate and save a few bucks on gas, switch to CO2—this wire handles both with ease. The 60lb spool size is perfect for shop welders who are burning wire all day and hate stopping every few hours to swap out a standard 33lb or 44lb spool. It’s a workhorse wire for workhorse welders.

Why Welders Choose Quantum Arc D2:

• Superior strength for heavy equipment repairs
• Smooth arc with minimal spatter to clean up
• Excellent puddle control in all positions (with proper settings)
• Consistent feeding thanks to quality copper coating
• Trusted Hobart reliability
