69100509 - Bonarc ER70S-6 .035" Solid MIG Welding Wire - 5kg Spool

Reliable .035" MIG Wire for General Fabrication

Upgrade your welding results with the Bonarc ER70S-6 .035" Solid MIG Wire, designed to handle the rigors of daily fabrication work. This 5kg spool is the ideal "middle ground" size—lighter than the standard 33lb or 44lb industrial spools, yet offering significantly more runtime than small 2lb hobbyist spools. It fits most standard MIG welders equipped with the appropriate spool hub adapter, making it a favorite for automotive shops, maintenance departments, and light structural fabricators.

Welding sheet metal or structural frames requires a wire that can handle high currents without burn-through while minimizing spatter. The Bonarc S-6 formula excels here, generating very low spatter levels which translates to less time spent grinding and cleaning after the weld is done. The .035" (0.9mm) diameter is the industry standard for all-around versatility, capable of welding thin gauge sheet metal in short-circuit transfer mode or thicker plates in spray transfer mode.

The copper coating on the wire improves electrical conductivity at the contact tip, ensuring efficient energy transfer and extending the life of your consumables. Furthermore, the precision winding prevents the "bird-nesting" often associated with cheaper wires, ensuring that your wire feeder runs smoothly from the first inch to the last.

Application Versatility

• Sheet Metal: Excellent control prevents burn-through on thinner gauges.
• Structural Steel: High tensile strength meets the demands of load-bearing welds.
• Maintenance & Repair: The high deoxidizer content handles imperfect surface conditions often found in repair work.
