In order to guarantee that arc welding machine works high-efficiently and safety, it must be maintained regularly. Let customers understand
the maintenance methods and means of arc welding machine more , enable customers to carry on simple examination and safeguarding
by oneself, try one’s best to reduce the fault rate and repair times of arc welding machine, so as to lengthen service life of arc welding
machine .Maintenance items in detail are in the following table.
MAINTENANCE AND TROUBLESHOOTING
● Warning: For safety while maintaining the machine, please shut off the supply power and wait for 5 minutes, until
capacity voltage already drops to safe voltage 36V .

Observe that whether panel knob and switch in the front and at the back of arc welding machine
are flexible and put correctly in place. If the knob has not been put correctly in place, please correct;
If you can’t correct or fix the knob , please replace immediately; If the switch is not flexible or it
can’t be put correctly in place, please replace immediately; Please get in touch with our company
maintenance service department if there are no accessories.
After turn-on power, watch/listen to that whether the arc welding machine has shaking, whistle
calling or peculiar smell. If there is one of the above problems, find out the reason to get rid of; if you
can’t find out the reason, Please contact local this area our company agent or the branch company.
Observe that whether the display value of LED is intact. If the display number is not intact, please
replace the damaged LED. If it still doesn’t work, please maintain or replace the display PCB.
Observe that whether the min/max value on LED accords with the set value. If there is any difference
and it has affected the normal welding craft, please adjust it.
Check up that whether fan is damaged and is normal to rotate or control. If the fan is damaged,
please change immediately. If the fan does not rotate after the arc welding machine is overheated,
observe that whether there is something blocked in the blade, if it is blocked, please get rid of; If the
fan does not rotate after getting rid of the above problems, you can poke the blade by the rotation
direction of fan. If the fan rotates normally, the start capacity should be replaced; If not, change the
fan.
Observe that whether the fast connector is loose or overheated. if the arc welding machine has the
above problems, it should be fastened or changed.
Observe that Whether the current output cable is damaged. If it is damaged, it should be wrapped
up, insulated or changed.
Using the dry compressed air to clear the inside of arc welding machine. Especially for clearing up
the dusts on radiator, main voltage transformer, inductance, IGBT module, the fast recover diode
and PCB, etc.
Check up the bolt in arc welding machine, if it is loose, please screw down it. If it is skid, please
replace. If it is rusty, please erase rust on bolt to ensure it works well.
Whether the actual current accords with the displaying value. If they does not accord, they should
be regulated. The actual current value can be measured by the adjusted plier-type ampere meter.
Measure the insulating impedance among the main circuit, PCB and case, if it below 1MΩ, insulation
is thought to be damaged and need to change , and need to change or strengthen insulation.
