ARCCTS
The ARCCTS instruction is used with a move instruction to gradually change the welding current and
voltage during welding. A gradual change in the current or voltage is specified by an aimed value and
the length of the slope up/down section. The length of the slope up/down section is set from the move
start point. If no length is specified, the entire section of the move instruction is used.
<Example>
The current and voltage are gradually changed as the manipulator moves toward the move end point
specified by the move instruction. The aimed current and voltage values are 150A and 16.0V
respectively. The slope up/down section length is 100mm from the move start point.
