1.Connect electrode lead to terminal of desired polarity.
2.Set toggle switch to same polarity as the electrode cable connection.
3.Set toggle switch to "Output Control Remote."
4.Set mode switch to the desired position for the process to be used.
NOTE: Since the
1 . The electrode stickout when starting should be as close to procedural length as possible, and the tip of the electrode should be clean and held nearly touching the work.
2.Install the R3S voltage triangle to the position higher than the desired arc voltage, provided it does not result in out of range shutdown of the

1.Connect electrode lead to terminal of desired polarity.
2.Set toggle switch to same polarity as the electrode cable connection.
3.Set the toggle switch to "Remote."
4.Install voltage triangle to a position as close as possible to desired arc voltage.

1.Set the "Electrode Polarity" switch to same polarity as the electrode lead.
2.Check that "Feed Direction" is set to forward.
3.Set the "Trigger Interlock" switch as desired.
4.Set the "Meter Reading" switch to "Wire Speed" and adjust the "Wire Speed" rheostat so the meter reads the desired wire feed speed.
5.Set the "Meter Reading" switch to "Volts" and adjust the "Volts" rheostat so the meter reads the desired arc voltage. IMPORTANT: Make certain this setting is within the voltage output range of the power source setting.
6.Load the
