5. INSTALLATION INSTRUCTION
If the connecting cable is too long, it will have a great influence on the arcing performance as well
as the stability of the welding performance. Therefore,please use the recommended length.If you want
to reduce the voltage drop, please use a cable with a larger cross section.
1) Ground the cables with section area no less than 6mm2to the housing,the way is connecting
screw in the back of the power source to ground device;
2) Connect the power cable to the distribution box with the corresponding voltage level of the
welder . Do not connect the wrong voltage and ensure that the fluctuation of the input voltage is within
the allowable range;
3) Make sure that the input power cable, output electrode holder, and output earth clamp are
reliably connected. For the output interface, refer to the connection method below and tighten it
clockwise;
4) Please pay attention to the connecting terminal, DC welding machine has two connecting ways:
positive connection and negative connection. Positive connection: connect the electrode holder with
“-” terminal,while workpiece with the “+” terminal. Negative connection: workpiece with the“-”
terminal, holder with the “+” terminal. Choose suitable way according to the working situation. If
unsuitable choice is made,it will cause unstable arc, more spatters and conglutination. If such problems
occur, please change the polarity of the fastening plug.

6. OPERATION INSTRUCTION
1) Turn the power switch to “ON”,the power indicator lit up,cooling fan within the machine start to
work immediately
2) Please ensure the suitable welding current and arc force current according to the thickness of
the workpiece ,the diameter of the electrode, station and technology needs
3) Clip electrode to the electrode holder,the machine is in the manual welding mode and standby
state.

230-280A
4) Arc force adjusting function is used to adjust the welding performance, specially in vertical and
overhead welding.With the use of welding current adjusting knob,it can achieve the ideal effect of
welding.
5) When welding in wet, high altitude, narrow, metal containers and other places, it is
recommended to use the VRD function which can ensure the no-load output voltage is about 14v-24v .
(VRD indicator is on, VRD function is on)
WARNING!
Before connecting operation,please make sure all the power is turned off. The right
order is to connect the electrode cable and earth clamp cable to the machine first, and make sure
they are firmly connected and then put the power plug to the power source.

7. PRECAUTIONS
1) Environment
① The machine should be operated in dry environments with humidity level of max 90%.
② Ambient temperature should be between -10 to 40 degree centigrade.
③ Avoid welding in sunshine or drippings. Do not let water infilter the machine.
④ Avoid welding in dusty area or the environment with corrosive gas.
2) Safety norms
The welding machine is installed with protection circuit of over voltage, over current and over
heat. When voltage, output current and temperature of machine exceed the required standard, welding
machine will stop working automatically. However, overuse (such as over voltage) will still result in
damage to the welding machine. To avoid this, the user must pay attention to the following notes.
① The working area is adequately ventilated!
The welding machine is powerful machine.When it is being operated, it generated by high current,
under this situation,natural wind will not satisfy machine cool demands. So a fan is used into
inner-machine to cool down itself. Make sure the intake is not blocked or covered.The objects around
the welding machine should be kept away not less than 0.3 meters.Make sure the working area
adequately ventilated is specially necessary. It is vitally important for the performance and longevity of
the machine
② Do not over load!
The operator should remember to watch the max duty current (Response to the selected duty
cycle). Keep welding current is not exceed max duty cycle current. Over-load current will damage and
burn up machine.
③ Do not over voltage!
Power voltage can be found in diagram of main technical data. Automatic compensation circuit of
voltage will assure the welding current keep in allowable range. If power voltage exceeds the allowable
range limited, it will damage to components of machine. The operator should understand this situation
and take preventive measures.
④ There is a grounding screw behind welding machine, with a grounding marker on it. Before
operation , welding crust must be grounded reliable with cable which section is over 6 square
millimeter, in order to prevent from static electricity , and accidents possibly caused by electricity
leaking.
⑤ If welding time exceeds the duty cycle limited, welding machine will stop working for
protection. Because machine is overheated, temperature control switch is on “ON’’ position and the
indicator light is yellow (red). In this situation, you needn't pull the plug, in order to let the fan cool the

machine. When the indicator light is off, and the temperature goes down, it can weld again.
8. MAINTENANCE
1) Remove dust by dry and clean compressed air regularly, if welding machine is operating in
environment where is polluted with smokes and pollution air, the machine need remove dust every
month.
2) Pressure of compressed air must be within the reasonable range in order to prevent damaging
to small components of inner-machine.
3) Check internal circuit of welding machine regularly and make sure the circuit connections are
connected correctly and tightly (especially plug-in connector and components). If scale and rust are
found, please clean it, and connect again tightly.
4) Prevent water and steam from entering into the machine. If that happens, please blow it dry
and check insulation of machine.
5) If welding machine will not be used for long time, it must be put into the packing box and
stored in dry and clean environment.
