S307308-033 - Hobart Quantum Arc 3 ER70S-3 .035 MIG Wire 33lb Reel

Smooth Feeding .035" MIG Wire for Production Welding

When your production line demands speed and your steel is clean, Hobart Quantum Arc 3 is the wire you reach for. This .035-inch solid wire is built for welders who need a consistent, smooth-running arc without the hassle of constant contact tip burn-back or bird-nesting. The "Quantum Arc" series is famous for its feedability, making it a favorite for both manual welders and automated robotic cells. If you are welding automotive frames, metal furniture, or light sheet metal, this wire offers the control you need to move fast without sacrificing quality.

One of the biggest frustrations in MIG welding is dealing with the glassy silica deposits that form on top of the weld bead. Because Quantum Arc 3 is an ER70S-3 class wire, it has a chemical composition that naturally produces fewer of these islands compared to standard ER70S-6 wires. This means less chipping and wire brushing between passes or before painting. It runs beautifully on straight CO2 for deep penetration but really shines with a 75/25 Argon/CO2 mix for a smooth, flat bead with minimal spatter.

This product comes on a durable 33 lb steel reel (Sr), which fits standard industrial wire feeders. The steel reel prevents the flange breakage often seen with plastic spools, ensuring your wire feeds true until the very end. Whether you are fabricating railcars, storage bins, or general structural components, Hobart Quantum Arc 3 delivers the professional results and reliability that keep the arc on and the job moving.
