5.1 Precautions
Warning! Dropping may cause machine damage or personal injury. Please
handle the machine in accordance with the handling and placement labels on
the machine, and use a cart or similar tools with an appropriate load-bearing
capacity for handling.
1) Machine lifting method: The machine can be lifted by fork lift or crane. As the machine is not
equipped with lifting rings, special attention should be paid to fixing method when using crane for
lifting.
2) Input cable specification: A cable of 3×4mm
2
or above should be used to connect the power
distribution box and machine. The power distribution box must be equipped with a breaker or fuse of
not less than 60A.
3) Protective earth lead connection: Be sure to connect the yellow-green wire in input cable of the
machine to the protective ground.
4) Cooling method: The water tank is provided with a cooling fan. The air inlet and outlet of the machine
cannot be blocked during its use to ensure the machine is ventilated well.
5) The inclination of the machine should not exceed 10°. Otherwise, it is prone to tipping over. When the
machine is put on a slope, additional fixing measures should be taken to prevent the machine from
sliding.
6) The operation environment of the machine should meet the following requirements:
a) Air temperature range:
During the welding, the temperature range is -10℃ ~+40℃. When the ambient temperature is lower
than 7℃. During the transportation and storage, the temperature range is -20℃ ~+55℃.
Note: When using a water cooler, pay attention to prevent it from being used or stored at the
solidification temperature of the coolant; when storing at a low temperature, the coolant
should be drained first!
b) Relative air humidity: not more than 70% at 40°C and not more than 90% at 20°C.
c) The dust, acid, corrosive gas, or substances in the surrounding air should not exceed the normal
content, except for these substances produced in the welding process.
7) The bottom of the equipment is equipped with rollers. When the equipment is put at a place, the
rollers should be locked to avoid damage or personal injury due to the equipment movement.
8) Do not put hands, hair, tools, etc. near the live devices in the machine when it is energized, such as
fans, so as to avoid personal injury or damage to the machine.
9) Avoid water or water vapor from entering the inside of the machine. If such condition occurs, the
