Practically, it’ll work with any type of mild steel that can be weld using a MIG welder. It’ll produce an inconsistent, kind of lumpy weld.Īmong its applications are assembly welding, railroad repairs, and light construction work. You don’t want to use this wire if your application requires multiple passes. Hence, it’s more suitable for single run welds. You’ll find that this wire runs hotter than solid wires. Despite being a self-shielded wire, I felt the urge to put some shielding gas on, but this is a wrong practice, so I’d take a point away for that. Feeding it into the welder was smooth with minimum spatter. True to their claim, I faced no difficulty using this core in my open workspace. I decided to kickstart the top product’s list with Forney’s flux core for one reason its unmatched tensile strength.įorney’s manufacturers claim it’s excellent for outdoor welding in windy conditions. If you need more testimonials, I encourage you to give Amazon reviews a look. It’s ideal for welding zinc-coated steel.Īccording to the manufacturer, this wire’s applications include tanks, repair work, earthwork, and steel building. Besides, it has a high deposition rate resulting in a beautiful weld bead. It works with DC straight polarity electricity. It has an above-average tensile strength of 82.7 KSI, and as I said before, it requires no shielding gas. Regarding mechanical properties, this wire is worthy of respect. You can use it for single or multi-pass welds, in addition to using it in all positions, vertical and horizontal. What I like about INETUB’s flux wire is its versatility. There are 2 spool sizes of INETUB the 4 inches (2 pounds) spool and a bigger 8 inches (10 pounds) one. You can use the 0.030 for mild metals, or you can opt for the 0.035 for thicker gauges. It has a similar set of properties at a reasonable price too. INETUB is also made in Italy, just like Inefil. You can see why it’s easily one of my favorites! It feeds smoothly into the welder with low spatter and produces a beautiful smooth arc. Another interesting wire to look at is the self-shielded INETUB carbon steel gasless flux core wire.
