Coreshield 15

Coreshield 15 is an all‑position self‑shielded flux‑cored welding wire designed for single‑pass applications on thin‑gauge galvanized and mild steels.

Key Features

• Smooth arc action with full slag coverage and easy slag removal
• Low spatter and DCEN polarity to reduce burn‑through risk
• Suitable for lap and fillet welds on materials as thin as 0.8 mm (18 gauge)
• Available in multiple diameters (0.8 mm‑1.6 mm) for a range of amperage and voltage settings
