Optimal
Optimal is an electrode for welding unalloyed and low-alloyed steel. It is especially suitable for welding thin sheets and thin-walled pipes and profiles. The electrode is characterised by fine drop transfer, low spatter, very finely rippled seam surfaces without undercutting and easy slag removal. Ignition, re-ignition and welding is also possible with low current. The arc is smooth and stable.
