69102009 - Bonarc ER70S-6 Solid MIG Welding Wire, 0.035 in, 20kg Spool

Smooth Running Wire for Professional Results

When you are laying down beads all day, you need a wire that runs smooth and keeps spatter to a minimum. The Bonarc 70S-6 .035" MIG wire is built to make your job easier and your welds look better. Whether you are working on an automotive restoration, building a trailer, or handling general shop repairs, this solid wire delivers a crisp, stable arc that is easy to control. The "S-6" classification means it is loaded with just the right amount of deoxidizers, so if your steel isn't perfectly clean—maybe it has a bit of mill scale or surface rust—this wire will help chew through it and leave you with a solid, clean deposit.

We know that nothing is more frustrating than a wire feeder that jams or surges because of a bad spool. That is why Bonarc ensures this 20kg spool is precision wound. The wire lays flat and feeds out consistently, which means you spend less time fixing bird nests and more time under the hood. The 20kg size is perfect for shop welders who go through a lot of consumables and don't want to be swapping out small spools every few hours.

This .035" wire is the "goldilocks" size for most fabrication jobs. It is thin enough to handle sheet metal without blowing through if you dial your machine down, but it has enough body to lay down serious metal on thicker structural steel brackets and frames. It works great with straight CO2 for deep penetration, or with a C25 (Argon/CO2) mix if you want that classic buzzing sound and a beautiful, flat bead profile.

Why Choose Bonarc 70S-6?

• Forgiving Arc: Handles imperfect metal preparation better than S-3 wire.
• Great Appearance: Fluid puddle wets out nicely for professional-looking tie-ins.
• Reliable Feeding: Precision winding protects your liner and contact tips.
