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(still in validation) 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 (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 being damaged.
4)Avoid rain, water and vapor 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, can the machine 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 to be used for a long time.

8.1. Common Malfunction Analysis and Solution
Malfunction Phenomena
Causes and Solutions
Turn on the machine, the power
indicator does not illuminate, the
fan doesn't work, and no welding
output.
(3)
Check if the power switch is closed.
(4)
No input power.
Turn on the machine, the fan works,
but the output current is unstable
and can't be controlled by
potentiometer when welding.
(3)
The current potentiometer fails. Replace it.
(4)
Check if any loose contact exists inside the machine. If any,
reconnect.
Turn on the machine, the power
indicator illuminates, the fan works,
but no welding output.
(4)
Check if any loose contact exists inside the machine.
(5)
Open circuit or loose contact occurs at the joint of output
terminal.
(6)
The overheating LED illuminates.
a)
The machine is under overheating protection status. It can
recover automatically after the welding machine is cooled.
b)
Check if the thermal switch is ok. Replace it if damaged.
c)
Check if the thermal switch is loosely connected, and
reconnect it if necessary.
The electrode holder becomes very
hot.
The rated current of the electrode holder is smaller than its actual
working current. Replace it with a bigger rated current.
Excessive spatter in MMA welding.
The output polarity connection is incorrect. Exchange the polarity.
