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 is specially formulated to be similar to EM13K solid wire

• Improved tolerance to rust and mill-scale than EM12K solid wire and SubCOR EM12K-S cored wire

• 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 EM12K and EM13K solid wires

• Helps reduce material preparation requirements and potential for porosity and part rework

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.
