Operang precauons
Liing method of the welding machine:
Please li this welding machine with a forkli or a
crane, and pay special aenon to the xing of the
machine when liing it with a crane for no liing
rings are assembled for this welding machine.
Specicaon of the input cable:
Connect the welding machine with a cable of
4*4mm
2
, and the switching box should be equipped
with a suitable circuit breaker or fuse. Always use a
suitably qualied person to connect to the mains
supply.
Connecon of the grounding wire:
Make sure that the yellow/green wire of the input
cable of the welding machine is connected to the
protecve ground in the welding area when
operang.
Cooling mode of the welding machine:
This machine uses forced air-cooling, so there
should be no obstrucons at the air inlet and outlet
of the welding machine so as to ensure good
venlaon.
Ingress protecon of the welding machine:
The ingress protecon of this machine is IP21S, and
it is not suitable to use in the rain. In addion, try to
avoid placing the machine in damp environment.
Duty cycle of the welding machine:
The rated duty cycle of this machine is 60%.
Overheang protecon is available for this machine,
and the machine would cut o output automacally
when overheang protecon occurs.
Inclinaon of the welding source:
The inclinaon of the welding source should not be
greater than 15
0
, or it would p over.
Operang environment of the welding machine:
The environment should meet the requirements
below:
a) Ambient temperature range: -10
0
C~+40
0
Cduring
welding; -25
0
C~+55
0
C during transport and storage.
Note: When using a water cooler, please ensure
that the coolant contains an freeze. Empty the
coolant rst if you want to store it at a low
temperature.
b) Relave humidity of the air: not greater than 50%
at 40
0
C; not greater than 90% at 20
0
C.
c) Dust, acid or corrosive gas or materials in the
ambient air should not exceed the standard
content, except for such materials produced in the
process of welding.
Never use this welding source for pipe thawing.
Do not expose the welding machine in the sunlight
for a long me, and try to avoid using the welding
machine in strong sunlight.
Keep hands, hair and tools away from the moving
parts such as the fan to avoid personal injury or
machine damage.
Avoid rain, water and vapor inltrang the machine.
If there is, dry it and check the insulaon of the
equipment (including that between the connecons
and that between the connecon and the
enclosure). Only when there are no abnormal
phenomena anymore, the machine can be used.
The welding machine and welding torch has its
rated duty cycle respecvely. Use them according to
their duty cycle, and overloading running is not
allowed.
Use appropriate welding cable: If the cable is overly
thin, the current would be insucient, the arc
stability would be poor, rated output power could
not be obtained, and the cable could be easily
burned.
Correct connecon is a precondion to ensure good
welding, so make sure that the output terminals of
the welding machine are connected correctly.
Using a water-cooled torch:
In order to prevent the welding torch against being
burned, the water pressure of the cooling water
should be 1~2kg/cm

.Even if the current is low,
