6.2 Safety tips
Ventilation
This welder can create powerful welding current that has strict cooling requirements that cannot be met with natural ventilation.
Therefore the built-in fan is very important in enabling the machine to work stable with effective cooling. The operator should
make sure that the louvers be uncovered and unblocked. The minimum distance between the machine and nearby objects
should be 30 cm. Good ventilation is of critical importance to the normal performance and lifespan of the machine.
Overvoltage is forbidden
Regarding the power supply voltage range of the machine, please refer to “Main Parameters” table. This machine is of
automatic mains voltage compensation, which ensures that the welding current varies within the given range. In case that the
input mains voltage exceeds the tolerance value, it would possibly damage the components of the machine.
Overload is forbidden
Remember to observe the max load current at any moment (refer to the corresponding duty cycle). Make sure that the welding
current should not exceed the max load current. Overload could obviously shorten the machine’s lifespan, or even damage the
machine.
Overheating protection
A sudden halt may occur with the overheating LED on while the machine is of over-load status. Under this circumstance, it is
unnecessary to restart the machine. Keep the built-in fan working to lower the temperature inside the machine. Welding can be
continued after the inner temperature falls into the standard range and the overheating LED is off.
7 Maintenance
WARNING!
The following operation requires sufficient professional knowledge on electric aspect and
comprehensive safety knowledge. Operators should be holders of valid qualification certificates
which can prove their skills and knowledge. Make sure the input cable of the machine is
disconnected from the electricity utility before uncovering the welding machine.
• Check periodically whether inner circuit connection is in good condition (especially plugs). Tighten the loose connection. If
there is oxidization, remove it with sandpaper and then reconnect.
•
Keep hands, hair and tools away from the moving parts such as the fan to avoid personal injury or machine damage.
• Clean the dust periodically with dry and clean compressed air. If welding environment with heavy smoke and pollution, the
machine should be cleaned daily. The pressure of compressed air should be at a proper level in order to avoid the small
parts inside the machine being damaged.
•
Avoid rain, water and vapour infiltrating the machine. If there is, dry it and check the insulation of the equipment (including
that between the connections and that between the connection and the enclosure). Only when there are no abnormal
phenomena anymore, the machine can be used.
• Check periodically whether the insulation cover of all cables is in good condition. If there is any dilapidation, rewrap it or
replace it.
• Check periodically whether the gas hose is in good condition. If there are any cracks, replace it.
• Put the machine into the original packing in dry location if it is not used for long time.
