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.

BENEFITS

●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
●Allows the use of high-productivity welding parameters without sacrificing weld strength or toughness
