Bohler Fox EV 50 Dry System 30 4.0 mm x 450 mm 2.7kg

The Böhler FOX EV 50 Dry System 30 is a basic-coated, low-hydrogen welding electrode engineered to deliver exceptional weld quality, strength, and toughness — even at temperatures as low as –50°C. Offering a metal recovery rate of approximately 110%, this electrode provides high efficiency, reliability, and performance across demanding industrial applications.

With excellent weldability in all positions except vertical down, the FOX EV 50 ensures smooth, stable arcs and clean, defect-free welds. It features a moisture-resistant coating and very low hydrogen content (HD < 4 ml/100g weld metal) in accordance with AWS standards, minimizing the risk of hydrogen-induced cracking and ensuring dependable results on steels with low purity or high carbon content.

Designed for structural, pressure vessel, shipbuilding, and offshore applications, this electrode is CTOD tested at –10°C and approved for sour gas environments (HIC-Test acc. NACE TM-02-84). SSC-test results are also available, confirming its suitability for critical and high-stress service conditions.
