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: 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.

Maintenance items
Daily
examination
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

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.
