Terminal name
Explanation
Output
21 H-CY VLV COM
Common terminal of the cylinder solenoid valve signal output
terminal.
22 H-MODE (*2)
Terminal for switching the auto mode and the fine weld mode.
When the circuit is open,
“auto mode” is selected.
When the circuit is closed,
“fine weld mode” is selected.
24 0V
0 V output terminal.
25 24V
24 V output terminal.
*1: For the timing of the main welding start input (H-ST2) from the motor controller, refer to 6. (1), (2),
(3), and (4) in the timing chart of the touch start. Only in “fine weld mode”, it is the timing from
weld point (initial current) to head up.
*2: For “auto mode” and “fine weld mode”, refer to 4. (6) (i) and 5. (6)-2.
*3: The GAS input is an input signal from the controller of the touch start head. Gas flow not
converted into pre-flow in the Welding conditions setting. (Refer to operation and control flow
in 5. (6) and timing chart in 6. (1).)
