Manifestation:

In the welding state, after pulling the trigger, the air is sent to the wire, and the red light is normally visible, but the laser cannot be emitted


Cause analysis:

Logically, when the gas is out, the outgoing signal will also be sent out. When the laser does not receive the outgoing signal (port failure) or the laser has a problem


Solution；

(1) First exclude the presence of an alarm in the laser itself


(2) Where it involves normal after shutdown and restart, most of them may be resettable alarms of the laser itself, it is recommended to contact the laser manufacturer or monitor the internal alarm


(3) For whether the laser has received a trigger signal, two schemes to test

The simplest thing is to link the laser's monitoring software to see which signal is missing. In addition, the signal port of the signal interface three can be measured Typically, the laser emits light only when it receives an enable/PWM/analog signal, so we can measure whether the signal is emitted in the operating state

(Please be sure to measure each port of signal interface 3 and unplug the laser wire in working condition when air output)
Enable signal: 2/4 pin output 24V voltage;
PWM modulation demodulation signal: 6/7 pin Output voltage 24V;
Analog signal: 4/5 pin equal proportional voltage, 10V at full power;
If the above signal is normal and still does not emit light, contact the laser manufacturer to deal with it;
Wenn eines der Freigabe-/PWM-Signale keine Spannung hat, kann es zusammen verwendet werden, z. B. PWM, das den Freigabesignal-Pin verbindet;
Wenn die analoge Größe keine Spannung enthält und das rote Licht eine Linie ist, kehren Sie zum Werk zurück, um das Motherboard zu reparieren oder auszutauschen.
Wenn im Analog keine Spannung anliegt und das rote Licht ein Punkt ist, überprüfen Sie, ob das 15-V-Schaltnetzteil ± vertauscht ist.
