RECOMMENDED FLUXES

• Metal-cored wire can offer improved deposition rates compared to solid wires at comparable amperages

• Metal-cored wires offer broader penetration profiles compared to solid wires at comparable welding parameters

• Weld deposit chemical composition requirements are identical to those of EF3 solid wires

• Weld deposit chemical composition consists of less than 1% nickel

• Very good low-temperature impact toughness in both the as-welded and stress-relieved conditions

• Provides potential to increase travel speed for improved productivity

• Helps to prevent burn-through when welding at high currents on root passes and relatively thin materials.

• Suitable as a higher-productivity alternative in many applications currently using EF3 solid wire

• Suitable for use in sour gas applications where stress corrosion cracking due to hydrogen-sulfide is a concern

• Helps minimize the risk of cracking in critical applications and harsh service environments

TYPICAL OPERATING PARAMETERS*

Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical depending
on the type and thickness of steel being welded.
Parameters are provided for informational purposes only. All values are approximate. The optimal voltage may vary (typically ±2 volts) depending on the choice of flux, material thickness, joint design, and other variables specific to the application.
Likewise, actual deposition rate may vary depending on choice of flux and contact tip to work distance.
