Independent source is the same as that on the robot side. Synergic/Independent of the welding

source can be set by the panel button
ing source panel. When "synergic (auto adjustment)" is selected, the LED indicator
"Auto Adj." lights. If the setting is different from that on the robot side, incorrect
welding voltage value is displayed on the panel. Furthermore, if the welding source
condition files of the robot are not correctly set, the robot command values are not
correctly displayed on the welding source panel.

tion selected. (0: Print servo 1: Servo torch, 2: 4-roller servo (YWE-WF340MELC))
If the motor is not correctly selected, the wire is not fed as instructed by the com-
mand value and welding performance becomes unsatisfactory.
Voltage If the voltage detection wire is disconnected, the 7-segment LED indicator for weld-
detection wire
ing voltage
ERR702 "Voltage detection wire error" is displayed on the 7-segment LED indica-
tors. Check if the voltage detection wire is correctly connected.

selected.
Record of After selecting the welding type or changing the parameter, save conditions before
conditions turning OFF the welder power supply. Before recording conditions, be sure not to
select other welding type while the user file is being adjusted because the changed
data on P parameters are deleted.
Encoder When the encoder cable is disconnected, or when the phases A and B are con-
cable nected inversely, the wire feeding becomes excessively fast or the motor runs
inversely. In addition, the 7-segment LED indicator for wire feeding speed
plays 0 and the error Err501 "Improper feeding amount" is issued. Check the con-
nection of encoder cable.
Shielding gas Check if the shielding gas suitable for the welding type is selected. For pulse weld-
ing, the argon ratio must exceed 80% to execute one pulse per drop. If short-circuit
occurs excessively during pulse welding, check the argon ratio.
Arc monitor When the arc monitoring function is used, refer to " 17 Setting of Arc Monitoring
Function ". The parameter set value is different from the MOTOWELD-S350.
