ARCPEX ER70S-6 MIG Welding Wire | 0.030" & 0.035" | Gasless Self-Shielded | Carbon Steel | 2LB Spool
ARCPEX ER70S-6 MIG Welding Wire delivers professional-quality, low-spatter welds on carbon steel and mild steel — ideal for auto repairs, metal fabrication, fencing, and home projects. Available in 0.030" (0.8mm) and 0.035" (0.9mm), in 1-pack, 2-pack, and 3-pack options.
✨ Minimal Spatter — Less Cleanup
Experience exceptionally low spatter with ARCPEX ER70S-6 solid MIG wire. Drastically reduce your post-weld cleanup time and achieve smooth, visually appealing beads on every project — saving both time and effort.
💨 Shielding Gas Compatible
Use with 100% CO2 or a mixed gas of 80% Ar / 20% CO2 as the shielding gas. Gas shielding delivers cleaner welds with lower spatter compared to flux core — ideal for indoor shop welding on clean metal.
🎯 Smooth Feeding — Beginner Friendly
Our ER70S-6 wire delivers flexibility and surface smoothness for steady, uniform wire feed — effectively preventing wire jamming and skipping. Combined with a stable arc, even beginners can effortlessly achieve continuous, smooth welds and significantly boost success rates.
