The solutions of welding head problem: do not feed wire

运行逻辑：送丝机通过尾部的两芯插头信号线，接到控制盒的信号接口二的5/6脚，系统运行时控制盒主板内置继电器吸合后5/6导通，送丝机开始工作（即5/6脚控制通断）

Operating logic:the wire feeder connects to the 5/6 pin of the signal interface of the control box by the two-core plug signal lines in the terminal. When the system is running, the built-in relay in the control box mainboard and 5/6 turns on, and the wire feeder starts to work (that is, the 5/6 pin controls the on-off).

当出现出气出光但不送丝的情况下：

When there is an outflow of light but no wire:

首先看送丝机的设置，脉冲参数是否正常，按照如图设置（个别版本没有脉冲功能，可以不用设置）

First look at the setting of the wire feeder, whether the pulse parameters are normal. Please set according to the figure (individual versions do not have a pulse function, you don’t need to set)

以上没有问题后，我们首先判定一下送丝机的控制有没有问题

If all the above is no problem, we first determine whether there is a problem with the control of the wire feeder

点击送丝机的前面板【手动送丝】，观察送丝轮是否在运转

Click on the front panel of the wire feeder [Manual Wire Feeding] to observe whether the wire feed wheel is running

1.送丝机不运转，送丝机本身有问题，更换主板

1. If the wire feeder does not run, the wire feeder itself has a problem, and please replace the mainboard.

2.送丝机运转，继续按照下面的操作进行

2. If the wire feeder runs, please continue to operate according to the instructions below.

我们首先短接送丝机的信号线，位于送丝机的尾部两芯航插头，拔掉后找一根线短接

We first short the signal line of the wire conveyor, which located in the tail of the wire feeder with two cores of the plug, and after unplugging, to find a wire to short connect.

1.送丝机运转，则可以判定送丝机没问题，继续按照下面的操作进行

1. If the wire feeder is running, you can determine that the wire feeder is no problem, and please continue to follow the following operation.

2.送丝机不运转，则可以判定送丝机主板有问题，更换送丝机主板

2. If the wire feeder is not running, it can be determined that there is a problem with the wire feeder mainboard and please replace the wire feeder mainboard.

针对第一种情况，把送丝机的尾部两芯航插头插上，在系统控制盒信号接口二的5/6脚拔掉，短接送丝机信号线（并非短接5/6脚）

In the first case, plug in the two-core aviation plug at the tail of the wire feeder, and unplug the 5/6 pin of the signal interface of the system control box. Then shorten the signal line of the wire feeder (not shorted to 5/6 pins).

1.送丝机不运转，则可以判定信号线有问题，更换信号线即可

1. If the wire feeder is not running, it can be determined that there is a problem with the signal line, and to replace the signal line is Ok.

2.送丝机运转，则可以判定系统主板有问题，更换系统主板或者使用下方的措施临时使用

2. When the wire feeder is running, it can be determined that there is a problem with the system mainboard, and please replace the system mainboard or use the following measures for a temporary use.

由信号接口二的3/4脚控制外置继电器来控制送丝机的信号线通断，接线定义如下（送丝机两芯信号使用继电器的常开脚）

The signal line of the wire feeder is controlled by the 3/4 pin of the signal interface two to control the signal line on and off, and the wiring is defined as follows (the two-core signal of the wire feeder uses the normally open foot of the relay)
