Maintenance
In order to guarantee that arc welding machine works high-efficiently and in 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.
● ● ● ● Warning: F

Maintenance items
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
Daily
intact, please replace the damaged LED. If it still doesn't work, please maintain or
examinatio
replace the display PCB.
n
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
Monthly
module, the fast recover diode and PCB, etc.
examinatio
n
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.
Quarter-
Whether the actual current accords with the displaying value. If they does not accord,
yearly
they should be regulated. The actual current value can be measured by the adjusted
examinatio
plier-type ampere meter.
n
Yearly
Measure the insulating impedance among the main circuit, PCB and case, if it below
examinatio
1MΩ, insulation is thought to be damaged and need to change , and need to change
n
or strengthen insulation.
