Installation Statements
1.Our series of plasma cutting power supply is equipped with power supply voltage compensation
device. When the power supply voltage changes within 15% of the rated voltage, it can still continue to
work. When using a long cable, in order to reduce the voltage drop, it is recommended to select a cable
with a larger cross-section; if the connecting cable is too long, it may have a greater impact on the arc
starting performance of the cutter and other performance of the system, such as the high-frequency arc
starting performance is weakened or the system can not work normally. So we recommend that you use
the recommended configuration length.
2.Make sure that the cutting power vent is not covered and blocked to avoid cooling system failure. The
enclosure shall be reliably grounded with a conductor with a conductive cross-sectional area of not less
than 6mm2 by connecting the wire from the back of the welding machine to the grounding device, or by
confirming that the grounding terminal of the power socket has been reliably and separately grounded. To
ensure safety, two methods can also be used at the same time.
3.Connect the gas inlet and compressed air source at the back of the cutting machine with the pressure
resistant air pipe, and fasten the interface with the throat hoop or other methods to avoid air leakage. And
ensure that the air source can provide appropriate pressure, sufficient flow, and is dry. If your existing gas
source cannot meet the above requirements, you should consider using a separate air compressor and gas
pressure reducing filter with sufficient power to ensure the normal operation of the machine.
4.Install the gas electric integrated connector of the cutting gun on the corresponding interface of the
cutting machine panel, and tighten it clockwise with a wrench. Connect the aviation plug on the cutting
gun to the corresponding interface of the cutting machine panel, and tighten the interface screw.
5.Insert the quick plug of the loop cable into the quick socket on the panel of the cutter, tighten it clockwise,
and clamp the workpiece with the ground wire clamp at the other end.
6.Connect the power line to the distribution box of the corresponding voltage level according to the input
voltage level of the welding machine. Do not connect the wrong voltage. At the same time, ensure that the
error of the power supply voltage is within the allowable range.
7.
Connect the corresponding cable according to the figure, and then proceed to the next step.
