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.

STANDARD PACKAGING

BENEFITS

●Provides potential to increase travel speed for improved productity
●Helps to prevent burn-through when welding at high currents on root passes and relatively thin materials.
●Suitable for welding a wide variety of 110 KSI (760 MPa) high-strength low-alloy (HSL A) and quench and tempered materials with matching mechanical properties
●Suitable as a higher-productivity alternative in many applications currently using EM4 solid wires
