Table. 3 Welding Preparation Procedure
Before Setting; Select the welding type according to
the type of shielding gas and wire, or short-circuit/
pulse.
Selectable types are written on the nameplate on the
front face of the panel. Set the welding type number to
the Type on the welding source panel.
Check the settings for the voltage, current, wire feed-
ing speed, and welding type of the digital meter on the
welding source panel. Check the indicated value on
the panel by changing command value from the robot
controller.
Adjust the welding wire by wire inching so that it can
be used for welding as follows:
1. Output the inching command from the robot
controller.
2. Inch the wire until it comes out from the end of
the torch.
Adjust the gas flow as follows:
1. Press the "Gas" button on the panel of weld-
ing source. The LED indicator lights and the
gas flows for 20 seconds. The gas automati-
cally stops after the 20 seconds. (The gas
flow time can be set by the parameter C00.
Refer to " 4.2.7 Checking the Flow Amount of
Shielding Gas ".)
2. Turn the valve of the gas cylinder counter-
clockwise to open.
3. Turn the knob of the gas regulator to adjust
the flow according to welding conditions.
Proper gas flow rate is 10 to 25 liters per
minute. The flow rate must be increased in
proportion to the welding current (the higher
the current, the larger the flow rate).
Save the conditions before turning OFF the welding
source as follows:
1. Keep on pressing the "Record" button for
more than three seconds to save changes.
Do not turn OFF the welding source while
saving.
2. The 7-segment LED indicators light up again
at the completion of the saving. Confirm that
the 7-segment LED indicators light again.
