BOHLER FOX EV 50-W 2,5x350mm/1,1kg/59pcs (73877) DrySystem 20

BÖHLER Fox Ev 50-W Electrodes - 2.5 × 350 mm / 1.1 kg / 59 Pcs / 73877 / Dry System 20

BÖHLER FOX EV 50-W are high-quality low-hydrogen basic electrodes designed for MMA welding of non-alloy structural steels, pipe steels and steel parts requiring a strong, tough and reliable weld. The electrodes are particularly suitable for root runs, assembly welding and more demanding joints where good arc control and high weld metal resistance to cracking are essential.

Thanks to the very low diffusible hydrogen content H4, they provide weld metal with good toughness even at lower temperatures. The electrode is characterised by good weldability in all positions except vertical down, a smooth weld appearance and easy slag removal.

The Dry System 20 packaging helps protect the electrodes from moisture and maintain their readiness for use when stored correctly. This is a practical solution for workshops, assemblies, service, maintenance, piping work and steel constructions.

Suitable Materials and Application

BÖHLER FOX EV 50-W is suitable for welding steels with a yield strength of up to approximately 420 MPa, structural steels, pipe steels and steel parts used in production, assembly and maintenance. It is used for welding steel structures, pipelines, low-pressure components, assembly units, frames, profiles and technical parts.

The electrode is particularly suitable where a high-quality root weld, good weld metal toughness and reliable welding in more demanding working positions are required.
