Detalles
Alambre con núcleo metálico de acero dulce, diseñado para brindar un desempeño del arco muy superior en aplicaciones de avance rápido o con alta velocidad de avance pero con una cantidad de salpicadura mínima
Características
- Inigualable desempeño en uniones que requieren de avance rápido y aplicaciones con alta velocidad de avance
- Optima acción de mojado del cordón aún con voltajes bajos
- El nivel de hidrógeno difusible es de H5
- Se recomienda aplicarlo con la Tecnología® de Control de Forma de Onda Rapid-Arc®
- La acción desoxidante del arco reduce el trabajo antes de la soldadura
