Operation logic: the wire feeder is connected to pin 5/6 of the signal interface II of the control box through the two-core plug signal line at the tail. When the system is running, the built-in relay on the main board of the control box is turned on after 5/6, and the wire feeder starts to work (that is, the pin 5/6 controls on and off).
When there is outgassing but no wire feeding:
First of all, look at the settings of the wire feeder and whether the pulse parameters are normal. Set the data in the red box as shown in the figure to be 0 (individual versions do not have pulse function, so you don’t need to set it).
After there is no problem above, let’s first determine whether there is any problem with the control of the wire feeder, click on the front panel of the wire feeder to see if the wire feeder wheel is running.
① If the wire feeder doesn’t work and there is something wrong with the wire feeder itself, disassemble the side cover of the control box, and measure the terminal voltage of the motor on the circuit board while pressing 【 Manual Wire Feeding 】. If there is voltage, change the motor, but there is no voltage to change the main control board.
②If the wire feeder is running, continue to follow the following operation: short the wire signal port with a wire; if the wire feeder is not running, it can be judged that there is something wrong with the main board of the wire feeder, and the main board of the wire feeder needs to be replaced at this time.
If the wire feeder is running, it can be judged that there is no problem with the wire feeder, and the problems of the system motherboard and signal line can be checked.
Unplug the signal wire of the wire feeder (angle 5/6 of signal interface II) on the control box, and measure the on-off of angle 5/6 in the welding state (individual models can apply the diagnostic function to open the IO port).
If it is in the access state at this time, the problem of the main control board of the system is ruled out, usually the signal line is open, and the multimeter can be used to confirm it again.
If the welding state is still open circuit, it means that there is something wrong with the motherboard, contact after-sales treatment.
When there is a problem with the main control board, the external relay can be controlled by the 3/4 pin of the signal interface II to control the signal line of the wire feeder for temporary use. The wiring definition is as follows (the normally open pin of the relay is used for the two-core signal of the wire feeder).
