Here is some information I found from one of the FCAW Electrode Manufacturers that can get you started with pretty good operating parameters. This information duplicates the parameters for ESAB Wires. ESAB has a great deal of information about their FCAW filler metals on in their FCAW Product Book

Other manufacturers should be consulted for exact setting. Also note, this is for E71T-1 wire with CO2. Values/Characteristics will change if using 75/25.
