When "OPEN MONITOR" is OFF in spot gun
condition data file, operation starts moving after
welding completion signal (Input) is input.
Stroke Change (Output) characteristics can be
changed by parameter.
Turns ON/OFF welding instruction, welding condition
and pressure instruction simultaniously.
However, strictly saying, output welding instruction
immediately after welding condition output.
