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.
