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

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

• Weld deposit chemical composition requirements are identical to those of EM1 solid wires

• Suitable for use with a wide variety of fluxes

• 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.

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

• Suitable as a higher productivity alternative in many applications currently using EM1 (or similar 80 ksi) solid wire

• Provides versatility in procedure development and optimizing the performance of the welding application

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.
