一、點(diǎn)火器的故障故障現(xiàn)象：按點(diǎn)火按鈕，有滋滋聲但不能著火

1、 Fault phenomenon of igniter: Press the ignition button, there is a buzzing sound but it cannot ignite

故障原因及排除：

Fault causes and troubleshooting:

1、高壓輸出端線路斷路，大部分為高壓線與高壓帽連接處尖頂螺栓雖擰緊但未接觸，重新壓接即可排除故障。

1. The circuit at the high-voltage output end is open, mostly due to the pointed bolts at the connection between the high-voltage wire and the high-voltage cap being tightened but not in contact. The fault can be eliminated by re crimping.

2、高壓輸出端引弧針與點(diǎn)火器回路短路或距離過近，未拉弧起火。絕緣處理、調(diào)準(zhǔn)距離或更換白色絕緣套管。

2. Short circuit or too close distance between the high-voltage output end arc striking needle and the igniter circuit, resulting in no arcing and ignition. Insulate, adjust the distance, or replace the white insulation sleeve.

3、高壓包接地螺栓處未連接好。重新接好即可。

3. The grounding bolt of the high-voltage package is not connected properly. Just reconnect it.

故障現(xiàn)象：按點(diǎn)火按鈕，機(jī)器突然停車，驅(qū)動(dòng)器22號(hào)報(bào)警（使用松下驅(qū)動(dòng)器系統(tǒng)的機(jī)器）。

Fault phenomenon: Press the ignition button, the machine suddenly stops, and drive number 22 alarms (machines using Panasonic drive system).

故障原因及排除：

Fault causes and troubleshooting:

高壓引弧線與機(jī)器外殼間短路或絕緣強(qiáng)度不夠，點(diǎn)火高壓將驅(qū)動(dòng)器及系統(tǒng)端口擊壞。此現(xiàn)象要避免，調(diào)試、維修時(shí)要仔細(xì)檢查。檢查線路絕緣電阻，1000V兆歐表大于300MΩ?；蚪殡娊^緣強(qiáng)度為5000V歷時(shí)1分鐘不擊穿穿。

Short circuit or insufficient insulation strength between the high-voltage arc line and the machine casing, resulting in the ignition of high voltage and damage to the driver and system ports. This phenomenon should be avoided and carefully checked during debugging and maintenance. Check the insulation resistance of the circuit, and the 1000V megohmmeter should be greater than 300M Ω. Or the dielectric insulation strength is 5000V for 1 minute without breakdown.

二、山東數(shù)控焊接設(shè)備的自動(dòng)調(diào)高器的故障（開通調(diào)高器）

2、 The malfunction of the automatic height adjuster of Shandong CNC welding equipment (opening the height adjuster)

故障現(xiàn)象：調(diào)高器不能升降

Fault phenomenon: The height adjuster cannot be raised or lowered

故障原因及排除：

Fault causes and troubleshooting:

1、調(diào)高器輸出功率管已燒壞，割槍只能向下，原因是調(diào)高器在限位接反及電機(jī)被卡死的時(shí)候，長(zhǎng)時(shí)間打開調(diào)高器極易發(fā)生。帶回調(diào)高器更換功率管。

1. The output power tube of the height regulator has been burned out, and the cutting gun can only be turned downwards. The reason is that when the height regulator is reversed in the limit position and the motor is stuck, it is easy to open the height regulator for a long time. Bring back the height adjuster to replace the power tube.

2、傳感器與控制器之間的同軸電纜阻抗不匹配，更換同軸電纜。

2. The impedance of the coaxial cable between the sensor and the controller does not match, replace the coaxial cable.

3、振蕩器輸出電壓不準(zhǔn)，檢查振蕩器參考電壓OUT、0V（即39KΩ電阻）兩端直流電壓是否為4.15V左右,否則調(diào)節(jié)電位器達(dá)到此值值。

3. The output voltage of the oscillator is inaccurate. Check whether the DC voltage at both ends of the oscillator reference voltage OUT and 0V (i.e. 39K Ω resistance) is about 4.15V, or adjust the potentiometer to reach this value.

三、斯達(dá)特系統(tǒng)常見故障

3、 Common faults of Start system

故障現(xiàn)象：

Fault symptom:

1、輸入無反應(yīng)，按動(dòng)急停等按鈕系統(tǒng)診斷下均無反應(yīng)。

1. The input is unresponsive, and there is no response when pressing the emergency stop button for system diagnosis.

2、輸出無動(dòng)作，發(fā)強(qiáng)電控制信號(hào)后，繼電器無動(dòng)作。

2. The output has no action, and after sending a strong current control signal, the relay has no action.

故障原因及排除：

Fault causes and troubleshooting:

一般為無24V電壓。用表測(cè)量24V電源有否，如無則穩(wěn)壓電源塊（78L24）或?yàn)V波電容損壞，更換即可。

Generally, there is no 24V voltage. Use a meter to measure whether the 24V power supply is available. If not, the stabilized power supply block (78L24) or filter capacitor will be damaged and can be replaced.

故障現(xiàn)象：輸入有輸出不正常。輸入可以測(cè)到（說明24V右），輸出無或部分無。

Fault phenomenon: Abnormal input and output. The input can be measured (indicating 24V right), but the output is either absent or partially absent.

故障原因及排除：

Fault causes and troubleshooting:

1、接線是否有斷處，可直接測(cè)量中間繼電器的控制線圈；

1. Whether there is a break in the wiring, the control coil of the intermediate relay can be directly measured;

2、如果線接觸良好，強(qiáng)電部分也沒問題，則可能是數(shù)控I/O板上2004集成電路有問題。I/O板上有3片2004，更換一下，看是否能排除。

2. If the wire contact is good and the strong current part is not a problem, it may be a problem with the 2004 integrated circuit on the CNC I/O board. There are 3 pieces of 2004 on the I/O board. Replace them to see if they can be ruled out.
