High-Strength Low-Alloy Solid MIG Wire for Demanding Structural & Heavy Fabrication Applications
Product Overview
The Talarc ER120S-G is a premium solid MIG welding wire engineered for welding high-tensile, low-alloy steels where superior weld strength, toughness, and crack resistance are critical. Supplied on a convenient 15kg spool at a 1.2mm diameter, this wire is a top choice for structural fabricators, mining equipment repair, earthmoving machinery, and offshore/marine construction projects requiring weld metal with a minimum yield strength of around 120,000 psi (827 MPa).
Manufactured to tight chemical composition and diameter tolerances, Talarc ER120S-G delivers smooth, spatter-free arc performance, excellent bead wetting, and consistent wire feeding — reducing downtime and rework on the shop floor or job site.
Key Features
- Ultra-High Tensile Strength – Produces weld deposits with a minimum yield strength of ~120,000 psi, ideal for high-stress structural joints
- 1.2mm Diameter – Versatile size suited to medium-to-heavy plate welding across multiple positions
- 15kg Spool – Bulk-format spool minimizes changeovers and maximizes productivity on long production runs
- Low-Alloy Composition (G-Type) – Formulated for excellent toughness and impact resistance, even in low-temperature service conditions
- Smooth, Stable Arc Characteristics – Consistent wire feeding with minimal spatter for cleaner welds and less post-weld cleanup
- Copper-Coated Surface – Enhances electrical conductivity and protects against corrosion during storage
- Tight Diameter Tolerance & Uniform Winding – Ensures reliable feedability through MIG guns and liners
Typical Applications
- Heavy structural steel fabrication and construction
- Mining, earthmoving, and construction equipment repair
- Offshore platforms and marine/shipbuilding structures
- Pressure vessels and high-strength steel frames
- Bridge building and infrastructure projects
- Repair and maintenance of high-tensile steel components
