CONTROL
Selects the welding control method.
COMB.
Combination control of constant-current and
constant-voltage controls
The constant-voltage control method and the
constant-current-control method function simultaneously,
and priority is given to the control method whichever
reaches the set value.
VOLT
Constant-voltage control
Controls so that the voltage detected by the V SENS cable
attached between electrodes will be the set voltage.
CURR
Constant-current control
Controls so that the welding current will be the set current.
5
START SIG. TIME
Sets the delay time between the input of the start signal and the start of the
weld sequence.
Under this setting, chattering of the start switch can be disregarded.
Select the set value from among 20 / 10 / 5 / 1 ms.
The delay time can be fully minimized when a non-chattering switch is used.
6
START SIG. HOLD
Selects the self-holding timing for starting.
SQ HOLD
Self-holding is valid from the beginning of the squeeze
sequence.
Even when the start signal is opened during the sequence
operation, the sequence does not stop.
WE HOLD
Self-holding is valid from the beginning of the weld
sequence.
When the start signal is opened during the squeeze time
(SQ), the sequence stops.
NO HOLD
No self-holding. Input the start signal until the end of the
sequence.
When the start signal is opened during the sequence
operation, the sequence stops.
Note) When the start signal is opened before the sequence
end, “E20:CYCLE TROUBLE” occurs.
