Manipulator starts moving by welding completion
(Input) signal when "GUN OPEN" is not specified
in spot input allocation information display.
Turns ON/OFF welding instruction, welding
condition and pressure instruction simultaniously.
However, strictly saying, output welding instruction
immediately after welding condition output.
Stroke Change (Output) characteristic can be
changed by parameter (Figure shows on setting at
FULL OPEN).
In case if the "GUN OPEN" is OFF, manipulator starts
moving immediately after the OFF of the signal

OFF
Stroke change is of a double solenoid method
(Stroke Change 1, 2) when an x gun double stroke
mechanical stopper type is used.
OFF
In case if the "GUN OPEN" is OFF, manipulator
starts moving immediately after the OFF of the
signal .
