Description
Hyundai Supershield 71GS is a high-performance, self-shielded flux-cored welding wire designed for efficient single-pass welding of thin mild and medium tensile steels up to 510 MPa. This wire is ideal for applications where external shielding gas is unavailable or impractical, such as outdoor welding and field repairs.
It is an all-position welding wire that offers smooth arc stability, low spatter, and full slag coverage, ensuring clean and efficient welds. With its excellent performance on DC(-) polarity, it is widely used in general fabrication, light structural work, and galvanized steel applications.
Key Features:
- Smooth arc stability with minimal spatter
- Full slag coverage for cleaner welds
- Suitable for all-position welding
- Operates on DC(-) polarity
- No external shielding gas required
- Ideal for outdoor applications and remote welding projects
Typical Applications:
- Light structural work
- Short assembly welds
- General fabrication
- Galvanized steel fixtures, gates, and railings
- Field repairs and maintenance welding
