62070309 - Bonarc ER308LSi .035 Stainless MIG Wire 300kg Drum

Smooth Feeding for Non-Stop Welding

If your shop burns through stainless wire by the pallet, the Bonarc ER308LSi 0.035" MIG Wire in the 300kg drum is the upgrade you need to keep the arcs lit. Designed for serious production environments, this bulk pack eliminates the constant interruption of swapping out small 33lb spools. It’s perfect for robotic setups or boom-mounted feeders where you need to run long, continuous welds without stopping.

What makes this wire stand out is the "HiSi" in the name. That stands for High Silicon, and for a welder, that translates to a puddle that flows like butter. The extra silicon helps the molten metal wet out better at the edges, giving you a flatter, smoother bead that requires less grinding and polishing later. If you are welding stainless tanks, countertops, or exhaust parts where the weld needs to look good right off the gun, this wire makes your job easier. It also helps stabilize the arc, reducing spatter so you spend less time cleaning nozzles and more time welding.

This wire is an ER308LSi classification, meaning it is the go-to choice for welding common 300-series stainless steels like 304 and 304L. The "L" stands for Low Carbon, which protects your welds from rusting from the inside out (intergranular corrosion) over time. It runs great on DC+ polarity and works well with standard stainless shielding gas mixes like Tri-Mix or Argon/CO2. The 0.035" diameter is the industry standard for all-around fabrication, giving you the versatility to weld thin sheet metal or thicker plate with the same setup.

The drum packaging ensures the wire comes out straight and tangle-free, provided you have the right payoff kit. No more dealing with the aggressive cast of a small spool fighting your liner. With Bonarc's consistent quality control, you get a wire that feeds reliably, arcs starts instantly, and lays down a bead you can be proud of, hour after hour.
