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 di erence and it has a ected 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 did
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 1M , insulation is thought to be damaged and need to change,
and need to change or strengthen insulation.
