69100506 - Bonarc ER70S-6 .023 Solid MIG Welding Wire - 5kg Spool

Smooth Feeding .023" MIG Wire for Auto Body and Sheet Metal

If you are tackling thin sheet metal projects, auto body repairs, or intricate HVAC work, the Bonarc ER70S-6 .023" MIG Wire is the reliable partner you need in your welder. This solid steel wire is famous for its "forgiving" nature. Thanks to its high silicon content, the weld puddle flows out smoothly (wets out) at the toes of the weld, helping you avoid that humped-up bead shape that requires hours of grinding. The .023-inch (0.6mm) diameter is the gold standard for thin gauge steel because it allows you to weld at lower amperages, giving you the control to bridge gaps and run beads without blowing holes through your workpiece.

We know that nothing ruins a welding session faster than a bird's nest in your wire drive. That is why Bonarc utilizes precision layer winding for these 5kg spools. The wire comes off the spool straight and true, reducing friction in your gun liner and ensuring the wire hits the joint exactly where you aim it. This smooth feeding capability translates to a steady, buzzing arc that sounds like frying bacon—the sign of a perfect weld. Plus, the copper coating on the wire aids in current transfer, extending the life of your contact tips and preventing the wire from rusting while it sits in your shop.

This wire is incredibly versatile when it comes to setup. You can run it with straight CO2 if you are on a budget and need extra penetration, or switch to a C25 (75% Argon / 25% CO2) mix for that classic, clean MIG weld with almost no spatter to scrape off later. It is tough enough to handle mild steel with a bit of mill scale or rust, saving you prep time on repairs. Whether you are restoring a classic car, building custom brackets, or fixing garden equipment, this Bonarc wire delivers professional-looking results with ease.

Why Welders Choose Bonarc .023:

• All-Position Capability: Great for vertical and overhead welds where puddle control is everything.
• Ready for Anything: The 5kg spool is the perfect size—enough wire for big jobs but light enough to keep your portable welder portable.
