2298F65 - ESAB Spoolarc 95 ER100S-1 0.035 MIG Wire 16kg

High-Strength Low-Alloy MIG Wire for Critical Applications

The ESAB Spoolarc 95 (AWS ER100S-1) is a premium copper-coated solid wire designed for the gas metal arc welding (GMAW) of high-yield-strength steels. This product is engineered to meet the rigorous demands of industries requiring welds with tensile strengths exceeding 100,000 psi. The wire chemistry is based on a Manganese-Nickel-Molybdenum alloy system, which provides a robust combination of high strength and superior ductility. It is specifically formulated to match the mechanical properties of quenched and tempered steels such as ASTM A514, A517, and military grades like HY-80 and HY-100.

This 16 kg (approx. 35.3 lb) spool offers a metric packaging standard often preferred in global manufacturing environments. The 0.035-inch diameter is versatile, allowing for welding in all positions when using short-circuit transfer, though it excels in spray transfer modes for flat and horizontal fillets on heavier plate. The Spoolarc 95 exhibits excellent Charpy V-Notch (CVN) toughness values at sub-zero temperatures, typically maintaining high impact resistance down to -50°F (-45°C). This makes it an essential consumable for fabricating heavy equipment, crane booms, mining machinery, and offshore structures where low-temperature performance is critical.

Metallurgically, the ER100S-1 classification ensures low hydrogen levels in the weld deposit, provided proper storage and handling procedures are followed. The wire's composition is tightly controlled to minimize impurities, reducing the risk of cold cracking in the heat-affected zone (HAZ) of sensitive base materials. For optimal results, shielding gases such as Argon/CO2 mixtures (e.g., 98/2 or 90/10) are recommended to maintain the alloy's mechanical properties while ensuring a stable arc. This product is a staple for MRO operations dealing with earthmoving equipment repair and structural steel fabrication requiring yield strengths in the 80-100 ksi range.
