62170801V - Bonarc ER316L Stainless Steel MIG Wire, .030 in, 1kg Spool

Smooth Running 316L Stainless Wire for Spool Guns

If you are looking for a reliable stainless steel MIG wire that runs smooth and leaves a professional-looking bead, the Bonarc ER316L is an excellent choice. This .030" (0.8mm) wire comes on a compact 1kg (2.2lb) spool, making it the perfect companion for your spool gun or smaller portable MIG welder. Whether you are fabricating custom marine hardware, repairing food truck equipment, or working on a stainless exhaust system, this wire delivers the performance you need without the bulk of a large industrial spool.

Welding stainless steel can be tricky, but Bonarc 316L is designed to make it easier. The wire feeds consistently, reducing the frustration of bird-nesting or burn-backs that can happen with lower-quality consumables. The "L" in 316L stands for Low Carbon, which is great news for your welds—it means the metal resists internal corrosion and cracking over time, keeping your project durable and rust-free even in harsh environments like saltwater or chemical exposure. The Molybdenum content adds that extra layer of protection against pitting that standard 308 wire just can't match.

For the best results, run this wire on DCEP (Direct Current Electrode Positive) using a Tri-Mix gas or a 98% Argon / 2% CO2 blend. You'll notice a stable arc with minimal spatter, meaning less time grinding and cleaning up after the weld. The bead wets out nicely, blending smoothly into the base metal for a sanitary and aesthetic finish. Keep a spool of Bonarc 316L in your truck or shop so you're always ready for those high-quality stainless jobs.
