S307608-033 - Hobart Quantum Arc 6 ER70S-6 .035" MIG Wire 33lb Spool

ER70S-6 Wire for Precision Welding

Hobart Quantum Arc 6 is an AWS ER70S-6 classified solid wire formulated for the welding of non-alloyed and fine grain steels. This 33 lb spool of .035" diameter wire is a staple for professional welders requiring a consumable that balances mechanical strength with operational ease. The wire's chemistry includes elevated levels of manganese and silicon, which act as deoxidizers to scavenge impurities from the weld pool. This makes it an excellent choice for applications involving steels with surface contaminants like mill scale or light rust, ensuring sound metallurgical bonds.

Superior Arc Characteristics

Welders will appreciate the smooth arc and low spatter levels associated with Quantum Arc 6. The wire exhibits excellent wetting characteristics, meaning the molten puddle flows out evenly to the toes of the weld, reducing the need for post-weld grinding or cleanup. This fluid puddle control is beneficial for achieving flat, aesthetically pleasing bead profiles in various welding positions. The copper-coated finish ensures optimal contact tip life and current transfer, essential for maintaining consistent penetration and fusion.

Technical Specifications & Usage

Designed for use with DCEP (Direct Current Electrode Positive) polarity, this wire operates effectively with wire feed speeds ranging from moderately slow to very fast, accommodating a wide window of welding parameters. It meets AWS A5.18 and ASME SFA 5.18 standards, making it suitable for code-quality work in pressure vessels, pipe, and tubing fabrication. From rail car manufacturing to general structural steel fabrication, the Hobart Quantum Arc 6 delivers the reliability and mechanical properties demanded by heavy industry.
