6. Installation and operation:
Attention: Please install the machine strictly according to the following steps !
The installation must be operated when the power is switched off !
The protection grade of the machine is IP21, so avoid to use the machine in the rain !
6.1 Installation:
(1) A primary power supply cable is available for the welding machine. Connect this power supply cable
to the rated input power.
(2) The primary cable should be tightly connected to the correct socket to avoid oxidization.
(3) Check the input voltage by multi-meter to assure the voltage is in the normal range.
(4) Insert the cable joint which is connected with the electrode holder into the output anode, fasten it
clockwise.
(5) Insert the cable joint which is connected with work clamp into the output cathode, fasten it clockwise.
(6) Make the grounding cable of the machine well earthed.
The connection as mentioned above in 6.1(4) and 6.1(5) is DCEP connection, operator could also
choose DCEN connection according to the material of workpiece and welding rod application
requirement. Generally, DCEP connection is recommended for basic electrode, while no special
requirement for acid electrode.
6.2 Operation:
(1) Turn the power switch (back panel) on, power LED on the front panel lights up and the fan begins
working.
(2) Pay attention to the polarity when connecting. Phenomena such as unstable arc, spatter and
electrode sticking could happen if improper connecting method is selected. Exchange the polarity if
necessary.
(3) If the workpiece is far away from the welding machine, the secondary cable (electrode holder and
grounding cable) is long, should choose cable with larger cross-section to reduce the voltage drop.
(4) Preset the welding current according to the type and size of the electrode, clip the electrode and then
welding can be carried out by short circuit arc starting. For welding parameters, please refer to the
6.3.

7.1 Working environment
(1) Welding should be carried out in dry environment with its humidity of 90% or less.
(2) The temperature of working environment should be between -10℃ and +40℃.
(3) Avoid working 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.
7.2 Safety tips
The welding machine has the over-voltage, over-current and over-heat protection. When the input
voltage, output current and the temperature inside the machine is beyond the set standards, the
machine will stop working automatically. However, overuse (for example too high voltage) can still lead
to the breakdown of machine, so please pay attention to the following instructions:
(1) Keep good ventilation!
When the machine is working, the natural air circulation can not cool down the high temperature
caused by big current flow, so a special fan is added to achieve the cooling.
Users need to make sure the back ventilator is not blocked or covered, and the machine should be
placed 0.3m away from the surroundings. It is important for users to keep good ventilation all the
time, it will be very helpful in improving the performance and service life of the machine.
(2) Over-load is forbidden!
The welding machine should be used as its duty cycle requires (refer to the corresponding duty
cycle), the welding current could not exceed the rated maximum output. The current overload will
shorten the service life of machine greatly, even destroyed.
(3) Over-voltage is forbidden!
The power voltage of the machine see the “Main parameter” table, in general situation, the
automatical voltage compensation circuit could keep the welding current in the normal range. If the
power voltage beyond the allowable values, it harms the machine, so the users should be aware of
this and take appropriate precautions.
(4) There is a grounding screw on the lower right corner of back panel. Before starting using the machine,
choose a wire (bigger than 2.5mm), and grouding the case to release static electricity.
(5) When the machine is working longer than the standard duty cycle requires, the temperature inside
the machine will be very high, it may start over-heat protection and stop working suddenly, and the
red light on the panel will light up. Under this situation, users do not have to remove the plug, so that
the fan on the back continues working and cool the machine down. When the red light is off, the
temperature goes down into the standard range, the machine could work again.
8. Maintenance:
Safety warning!
The following operation require the operator must have comprehensive electrical and safety
knowledge, as well as the qualifications. Make sure the input cable is removed from the power
supply before opening the casing.

(1) Check the circuit connection inside the machine regularly, if the wire joint or components is rusty or
loose, sand the rust and tighten the joint.
(2) Keep hand, hair, and tools away from the live parts, for example fan, to avoid injury.
(3) Clear the dust regularly with clean and dry compressed air. If there is heavy smoke and pollution in
the working environment, the welding machine should be cleaned once a month. The pressure of
compressed air should be controlled in a reasonable range or the small components in the machine
will be damaged.
(4) Avoid water or steam entering the machine, if it occurs, dry it in time and check the insulation with
mega meter (including that between the connection and that between the case and connection).
Start working again when nothing is abnormal.
(5) Check the cable of welding machine regularly, when insulation sleeve of cable is broken, repair or
change for new one.
(6) If the machine is no use for a long time, packing it into original box and leave it in dry place.
9. Trouble shooting:
Common problem and solution:
Common problem and solution:
Problem
Solution
Power LED does not light up, the fan
doesn’t work, no welding output
1. make sure the power is switched on
2. make sure the power source has electricity
The fan works, output current is not
stable or not controlled by current
adjustment
1. the potentiometer is breakdown, change for new one
2. Examine the connections inside the mahcine, fasten the
loose connection
Power LED lights up, the fan works, no
welding output
1. Examine the connector assemblies in the machine are
well connected.
2. Examine the joint of output is well connected.
3. Over heat LED is light up:
(1) the temperature inside the machine is too high and the
machine is in over-heat protection. Users do not have to
remove the plug, so that the fan on the back continues
working and cool the machine down. When the red light
is off, the temperature goes down into the standard
range, the machine could work again.
(2) Examine the thermo switch, if it’s damage, change for
the new one.
Electrode holder is hot
The rated current of electrode holder is smaller than then
actual output current, change for the right capacity one.
The splashing is big for MMA welding
The output connection method is not proper, change the
