10 Caution
10�1 Working environment
1. Welding should be carried out in dry environment with humidity of 90% or less.
2. The working environment temperature should be between -10 C° and 40 C°.
3. Avoid welding in the open air unless sheltered from sunlight and rain. Keep welder dry .
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.
10�2 Safety Tips
Over-current/over-voltage/over-heating protection circuit is installed in this machine. When the network voltage, output current
or inner temperature exceeds the setting standard, the machine will stop working automatically. However, excessive operation
(over voltage) will lead to welder damage. Therefore, please note:
1� Ventilation
This is an industrial welding machine and can create large current that requires strict cooling devices instead of natural
ventilation. Therefore the built-in two fans are very important to ensure effective cooling and stable working performance.
The operator should make sure that the louvers be uncovered and unblocked. The minimum distance between the machine
and nearby objects should be 30cm. Good ventilation is of critical importance to the normal performance and lifespan of
the machine.
2� Over-load is forbidden
The welder is operated according to allowable duty cycle (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
Please refer to “Technical Parameters” for the power supply voltage range. This machine is of automatic voltage
compensation to ensure the welding current is within the given range. In case that the input voltage exceeds the stipulated
value, it would possibly damage the components of the machine. The operator should take according measures to this
case.
4� Reliable ground connection
There is a ground screw (with ground remark) in the rear part of each machine. Connect it with an earth cable
(section ≥ 6 mm²) to avoid the static and electric shock.
5�
A sudden halt may occur with the front panel’s red indicator lighting up while the machine is of over-load status. Under this
circumstance, it is unnecessary to restart the machine for it’s resulted from over-heating and the triggered the temperature
control switch. Keep the built-in fans working to lower the machine’s temperature. Welding can be resumed when
temperature falls into the standard range and the red indicator is off.
11 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�
1. Check periodically whether inner circuit connection is in good condition. 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 being damaged.
4.
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.
5. Check periodically whether the insulation cover 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 used for long time.
