*5 Set H-HEAD UP and H-END signals’ output times to 200 ms. Refer to “4. (6)
(g) [Op-IO] H-END signal output time” and “(i)
[Op-IO] H-HEAD UP signal output time.”
*6 When the auto mode is set, the initial current time is the time when the head moves to weld point (main welding). However,
when the time when the head moves to weld point (main welding) becomes 500 ms or longer, the ST2 time error occurs.
Adjust the head moving distance and speed so that the moving time becomes within 500 ms.
*7 Set value of “END signal output time.” Refer to “4. (6)
(c) END signal output time.”
*8 Set value of “GOOD/NG signal output time.” Refer to “4. (6)
(b) GOOD/NG signal output time.”
*9 It becomes about 1300 ms when the High speed SCH change (No Wave) in 4. (6)
(h) is OFF and about 100 ms when it is ON.
However, when the END signal output time or the GOOD/NG signal output time is 100 ms or longer, it is made the same as OFF
of the longer set time. Also, it takes about 1700 ms when the current flows when ENVELOPE in the Limit output judgment on
the Monitor select screen is ON. Refer to ENVELOPE of “4. (11) (d)
Limit judgment output.”
*10 If the WELD STOP signal is input before the H-ST1 signal is input, the READY signal is turned OFF and the welding power
supply does not receive the H-ST1 signal during that period. Therefore, since welding does not start and the END signal is not
output, the head remain stopped at weld point (initial current). To clear the state, you need to turn the head controller off and
then back on or operate the emergency stop for the welding power supply and then reset.
