Détails
Un transfert d’arc fluide, de faibles éclaboussures et une bonne apparence de cordon en font une électrode de qualité supérieure. Les opérateurs apprécieront l'arc bien dirigé avec un transfert de petites billes.
Traits
- Transfert d'arc en douceur et faibles éclaboussures
- Conçu pour le soudage avec un gaz de protection 100 % CO2 ou 75 - 82 % d’argon/reste de CO2
- Bonne apparence du cordon de soudure
- Laitier à congélation rapide pour un soudage hors position
- Conforme aux exigences de la norme AWS D1.8 sur la dérogation de lot sismique
- Notes: AWS D1.8 structural steel seismic supplement test data can be found at the Lincoln Electric Certificate Center.
