Manual operation of welding (basic function of the use of methods)
Have to arc welding (self-locking, or arc Action)
Have to arc welding, weld at the end of filling the depression, and applied to the wood plate welding.
Operation sequence:
The arc will switch to place "at the Arc," will be twice torch switch? Relax welding.
As indicated above, through the operation of gun switch, can be self-locking. At the end of welding, welding current decreases, the resumption of arc.
However, in the welding process, when broken arc above 0 5 seconds, lifting the self-locking.

4． 高频引弧电路个别损坏，查找更换之。
Problems
Abnormal indicator light is off, no high frequency discharge with “sha sha” noise, arc striking effective.
Causes and Solutions
1. Poor contact between the primary cable of arc strike transformer and the power panel, retighten it.
2.Discharge nozzle oxidized or the gap too wide. Remove the oxide film on the nozzle or adjust the gap to 1mm.
3.Manual weld/argon weld interchange switch damaged, replace it.
4.Certain parts of the HF arc strike circuit damaged; find and replace them
异常指示灯亮，无输出
1． 可能是过流保护，请关掉机器，待异常指示灯灭掉再重新开机可恢复正常。
2． 可能是过热保护，不用关机等待2-3分钟可自然恢复正常。
3． 可能是逆变器或引弧板故障，请拔掉MOS板上的主变压器的供电插头（靠近风机VH-07插件）重新开机：
（1） 指示灯仍然亮，关机再拔掉引弧板上的供电源（靠近风机VH-03插件）重新开机：
a. 异常指示灯仍然亮则是MOS板上个别场管损坏，查找并更换同类型的场管。
b. 异常指示灯不亮则故障在引弧板，升压变压器坏，更换之。
（2） 把有故障逆变器的供电电源线插上，主变压器的电源线不插，再重启。
a. 如果异常指示灯不亮故障在中板，可能是中板变压器损坏，可用电桥测量每个主变压器初级电感及Q值。
b. 可能是中板整流管个别损坏，查找并更换同类的整流管。
4． 可能是反馈电路断。
Problems
Abnormal indicator light is on, no output current
Causes and Solutions
1.Possible activation of current overflow protection; turn off the machine, wait for the abnormal indicator light to turn off and restart the machine.
2.Possible activation of overheat protection; do not turn off the machine, just wait for 2 or 3 minutes, it will return to normal automatically.
3.Possible failure of the inverter circuit. Pull out the power plug of the main transformer on the MOS panel (near the ventilation fan VH-70), then restart:
(i) If the abnormal indicator light is still on, switch off the machine and pull out the power plug of the HF arc strike (near the ventilation fan VH-03 plug-in unit ), then restart:
a. If the abnormal indicator light is still on, it means individual effect tube on the MOS panel is damaged; find it and replace with the same.
b. If the abnormal indicator light is off, it means the problem is on the arc strike panel, the voltage boost transformer is damaged, replace it.
(ii) Plug in the supply cable of the failed inverter circuit, do not connect the supply cable of the main transformer, then restart:
a. If the abnormal indicator light is off, it means the mesoplax transformer possibly damaged, Use a bridge to measure the primary inductance and Q value of the main transformer.
b. Possible break down of individual rectifier diode of transformer. Check and replace it with similar diode.
4. Possibly a break in the reactive circuit
针烧损严重 占空比调节过大，将占空比减小
焊铝时无法破开氧化膜
1．焊接档位选择错误。
2．占空比过小。
3．二次逆变有场管损耗。
Problems
Tungsten pin badly burnt
Causes and Solutions
Duty ratio set too big,reset it to smaller ratio.
Problems
Unable to penetrate the oxide film during welding:
Causes and Solutions
1. Wrong selection of welding modes
2. Duty ratio adjusted too small
3. Field effect transistor damaged during double inversions.
The excrescent indicator isn't bright, having no high to turn on electricity"the sand sand" voice, "wipe the " can rise 1. Lead the transformer entry-level line with lead the plank contact bad, tightly solid afresh.
2. Turn on electricity the oxidizes or is apart from secluded, handle to turn on electricity the surface to oxidize the film or adjustment to turn on electricity is or so apart from the 1 mm.
3. The hand argon conversion switch injure, replacing it.
4. The high leads circuit to damage separately, checking to seek to replace it.
The excrescent indicator is bright, output 1. May be lead to flow a protection, please turn off machine, needing an excrescent indicator to destroy to re- switch on again can recover normally.
be abnormal indicator of New Jersey re-boot return to normal.
2. May is overheating protection, not wait for 2-3 minutes off natural back to normal.
3. May inverter board or arc fault, the main board MOS unplug the power supply transformer plugs (near Fan VH-07 plug-in) restarted:
(1) light is still bright, the board turned to unplug the arc for power (near Fan VH-03 plug-in) restarted:
A. Abnormal light is still bright MOS field of individual board damaged, locate and replace the same type of field.
B. abnormal light is not bright arc fault in the board, step-up transformer bad, the replacement.
(2) a failure of the inverter power supply line stuck, the main power line transdfdf is not inserted and then
wtf aluminum can't break
The excrescent indicator isn't bright, having no high to turn on electricity"the sand sand" voice, "wipe the " can rise 1. Lead the transformer entry-level line with lead the plank contact bad, tightly solid afresh.
2. Turn on electricity the oxidizes or is apart from secluded, handle to turn on electricity the surface to oxidize the film or adjustment to turn on electricity is or so apart from the 1 mm.
3. The hand argon conversion switch injure, replacing it.
4. The high leads the electric circuit to damage separately, checking to seek to replace it.
The excrescent indicator is bright, output 1. May be lead to flow a protection, please turn off machine, needing an excrescent indicator to destroy to re- switch on again can recover normally.
2. May be over hot protection, need not shut down to wait for for 2-3 minutes natural instauration normal.
3. May be go against to change a machine or lead the plank to break down, please pull out MOS plank up of the main transformer be provided for socket(close to the breeze machine plug-ins VH-07s) to re- switch on:
(1) Indicator still bright, shut down to pull out again to lead the plank up of the power supply source(close to the breeze machine plug-ins VH-03s) re- switches on:
a. Excrescent indicator still bright then the MOS plank ascend an individual field a tube damage, checking to seek and replace the field of the same kind type tube.
b. Excrescent indicator not bright the breakdown Be leading the plank, rising to press transformer bad, replace it.
(2) Have already broken down to go against power supply power cable of change the machine to put on, the power cable of the main transformer put, again heavy.
a. If the excrescent indicator isn't bright to break down at in plank, may be in the plank transformer damage, can use electricity bridge to measure each main transformer entry-level an electricity the feeling and Q value.
b. May be a medium plank to commutate a tube to damage separately, check to seek and replace to commutate a tube the same kindly.
4. May be the feedback electric circuit to break.
The needle burns to share seriously empty compare regulated greatly, will share empty compare let up
The aluminum can't break open to oxidize a film 1.weld the file choice mistake.
2.shared an empty ratio to lead small.
3.go against to become a tube to exhaust two times.
Bright light is not unusual, non-high-frequency discharge "swish" sound, "flattering Arc" can play an arc. Striking line transformer primary contact with the plate arc, re-fastening.
2. Tsui oxidation or discharge from the remote, processing discharge Tsui surface oxide film or adjusted discharge from the muzzle about 1mm.
3. Hand welding argon welding switch damage, a replacement.
4. High-frequency circuit arc individual damaged, the replacement search.
Very bright light, no one output. Overcurrent protection is possible to switch off the machine, to be abnormal indicator of New Jersey re-boot return to normal.
2. May is overheating protection, not wait for 2-3 minutes off natural back to normal.
3. May inverter board or arc fault, the main board MOS unplug the power supply transformer plugs (near Fan VH-07 plug-in) restarted:
(1) light is still bright, the board turned to unplug the arc for power (near Fan VH-03 plug-in) restarted:
A. Abnormal light is still bright MOS field of individual board damaged, locate and replace the same type of field.
B. abnormal light is not bright arc fault in the board, step-up transformer bad, the replacement.
(2) a failure of the inverter power supply line stuck, the main power line transformer is not inserted and then restart.
A. If no-fault indicator anomalies in the plate, the plate may be damaged transformer, the main electricity transformer bridge measuring each primary inductance and Q values.
B. Plate tube may be damaged individual, find and replace a similar tube.
4. May feedback circuit is broken.
Burning needles serious duty cycle adjust too large, the ratio will decrease
Welding aluminum oxide film can not be forced open one. Welding stalls wrong choice.
2. Duty cycle too small.
3. A second inverter in the loss.
