4. INSTALLATION INSTRUCTIONS
The induction power is equipped with power voltage compensation function. When rated output
voltage moves within +/-15%, it still can work normally.
When use long cable， you must choose bigger section cable to prevent the voltage drop；If cable is
too long, it may heavily influence the performance of the arc striking and the other power system. So
we suggest u use our recommend length.
1. Make sure the intake is not blocked or covered to prevent the cooling system couldn't work.
2. Choose the cable which section is not less than 4mm²to connect the housing to the ground.
3. Correctly connect the electrode holder and earth clamp as the following sketch.
4. Pay attention to the polarity, DC welder have 2 connecting ways : positive connection and negati-
ve connection .Positive connection ：holder connects with "-"polarity .While work piece connects
with "+".Negative connection depends on different work piece and technical requirement. If unsuita-
ble choice, it will cause unstable arc, more spatters and conglutination. If such problems occur,
please change the polarity of the fastening plug.
5. Connect the power line to the distribution box according to the input voltage classes of the
welding machine, don't connect the wrong voltage. And u must confirm that the input voltage within
bounds.
INSTALL SKETCH
Power 220~240v - 50/60 Hz
Power cable
Welding cable
Earth cable
If the distance of work piece and welder is too far (50-100m), and the cables (torch cable and earth
cable) are too long, please choose cable for bigger section to minimize the reduction of the voltage.
