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 6mm

to 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.
