COBRA wire is the choice for people who want to weld like a professional with consumables you can rely on. Cobra is one of the leading brands of wire which has a deep history entrenched in the Australian welding industry. S6 is a versatile mild steel welding wire that produces quality weld results even when used on dirty and contaminated steel. Although this is not recommended, it is due to the wire containing higher levels of manganese and silicon than S2 and S4. The high silicon content increases fluid in the weld pool which in turn, produces smooth bead appearance. This wire performs exceptionally well for general steel construction, sheet metal applications, pressure vessel applications, structural welding, and pipe welding.
