TROUBLESHOOTING AND FAULT FINDING 

Notes:  The  following  operations  must  be  performed  by  qualified  electricians  with  valid  certifications.  Before 

maintenance,please contact with us for professional suggestion.

 

Mini 160 fault symptom and solutions:

 

Fault symptom 

Solutions 

Indicator of power switch is not 

lit, fan is not working and there 

is not welding output. 

A. 

Make sure power switch is close. 

B. 

Make sure electrify wire net (which is connected to input cable) is in work. 

Power indicator is lit, fan does 

not work and there is no welding 

output. 

A. 

Maybe be connected wrong to 380V power cause machine is in protection 

circuit, connect to 220V power and restart the machine. 

B. 

220V power is not stabilizing (input cable is too slender) or input cable is 

connected to electrify wire net cause machine is in protection circuit. Increase 

the section of input cable and tighten input connector firmly. Close machine 2-3 

minutes then restart it. 

C. 

Open and close power switch continuously cause protection circuit is working. 

Close machine and restart it after 2-3 minutes. 

D. 

Cables  are  relaxed  between  power  switch  and  power  source  board,  tighten 

them again. 

Fan is working, welding current 

is not stabilizing or out of 

potential control, current is 

sometimes low and sometimes 

high. 

A. 

Quality of 1K potential is bad, replace it. 

B. 

Terminal of output is broken circuit or poor connect. 

Fan is working and abnormal   

indicator is not lit, there is no 

welding output. 

A. 

Check if components are poor connects. 

B. 

Check if connector of output terminal is break circuit and poor connect. 

C. 

Check voltage between power source board and MOS board (VH-07) is about 

DC 308v. 

D. 

If green indicator is not lit in assistant power of MOS board, please connect with 

seller or our company and replace it. 

E. 

If there is some question in control circuit, please connect with seller or our 

company and replace it. 

Fan is working and abnormal   

indicator is lit, but there is no   

welding output. 

B. 

Maybe over-current protection is working, please close machine and waiting. 

Restart it after abnormal indicator is off. 

C. 

Maybe overheated protection is working, wait for 2-3 minutes. 

D. 

Maybe inverter circuit is in fault; please pull up the power plug of main 

transformer (near VH-07 fan), which is on MOS board, then restart the machine. 

(1)  If abnormal indicator is still lit, some of MOS board is damaged, check and 

replace it. 

(2)  If abnormal indicator is not lit: 

i. 

Maybe transformer of middle board is damaged, measure primary 

inductance volume and Q value of main transformer by inductance 

bridge. 

ii. 

Primary value is parallel circuit, L=1.2-2.0Mh, Q>40, If inductance 

value and Q value is low, replace it. 

iii. 

Maybe some of secondary rectifier tube of transformer is broken, check 

and replace rectifier tube. 

E. 

Maybe feedback circuit is in fault.
