CAUTION
• Working Environment
(1) Welding should be carried out in dry environment with its humidity of 90% or less.
(2) The temperature of the working environment should be between -10ºC to 40ºC.
(3) Avoid welding in the open air unless sheltered from sunlight and rain. Keep it dry anytime and do not place it on wet
ground or in puddles.
(4) Avoid welding in dusty area or environment with corrosive chemical gas.
(5) Gas shielded arc welding should be operated in environment without strong airflow.
• Safety Tips
Over-current/over-voltage/over-heating protection circuit is installed in this machine. If the input voltage or the output
current is too high or machine inside temperature over heating inside, the machine will stop automatically. However,
excessive use (e.g. too high voltage) of machine may also damage machine, so please note:
1 Ventilation
High current passes when welding is carried out, thus natural ventilation cannot satisfy the machine's cooling
requirement. Maintain good ventilation through the louvers of the machine. The minimum distance between the
machine and any other objects in or near the working area should be 30cm. Good ventilation is of critical importance
for the normal performance and lifespan of the machine.
2 Welding operation is forbidden while the machine is overload. 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.
3 Over-voltage is forbidden.
Regarding the power supply voltage range of the machine, please refer to "Main Parameters" table. This machine is of
automatic voltage compensation, which enables the maintaining of the voltage range within the given range. In case
that the input voltage exceeds the stipulated value, it would possibly damage the components of the machine.
4 A sudden halt may occur while the machine is of overload status. Under this circumstance, it is unnecessary to restart
the machine. Remain the built-in fan working to lower the temperature inside the machine.
MAINTENANCE
(1) Check periodically whether inner circuit connection is in good condition (esp. plugs). Tighten the loose connection. If
there is oxidization, remove it with sandpaper and then reconnect.
(2) Keep hands, hair and tools away from the moving parts such as the fan to avoid personal injury or machine damage.
(3) 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 to be damaged.
(4) Avoid rain, water and vapor in filter the machine. If there is, dry it and check the insulation with equipment (including
that between the connections and that between the connection and the enclosure). Only when there are no abnormal
phenomena anymore, then the machine can be used.
(5) Check periodically whether the insulation covers of all cables is in good condition. If there is any dilapidation, rewrap it
or replace it.
(6) Put the machine into the original packing in dry location if it is not to be used for a long time
