2. INSTALLATION AND CONNECTION
2.1 Installation requirements
In order to ensure personal safety and avoid electric shock, please ground the machine reliably
by connecting the ground wire (yellow-green wire) of the machine to the grounding device in
the switching box.

)
Connection of input cable
A primary power supply cable is available for this cutting machine. Connect the power supply
cable to the rated input power. The primary cable should be tightly connected to the correct
socket to avoid oxidization. Check whether the voltage value varies in acceptable range with a
multi-meter.
The cross section of the leads used in the switching box should meet the requirements of the
maximum input capacity of the machine.

Connection of output cable
Connection of cutting torch
Connect the copper nut on the cutting torch to the
gas-electric connector on the front panel of the
machine, and tighten it clockwise to avoid gas
leakage. Insert the quick plug on the work clamp
into the “+” output terminal on the front panel of the
machine, and tighten it clockwise.
Connection of the torch trigger
Insert the plug of the torch trigger on the cutting torch
into the socket of torch trigger on the machine panel.
(For models with pilot arc function, connect the pilot
arc wire on the cutting torch to the terminal for pilot
arc wire on the machine panel.) Install the electrode
into the cutting torch by turning it slowly, and tighten
it. Then, get the nozzle and protective sleeve installed
in sequence.
Connection of earth cable
Insert the quick plug on the earth cable into the quick
socket marked with “ ” at the bottom of the front
panel of the machine, and tighten it clockwise. Clamp
the workpiece with the work clamp at the other end of
the earth cable.
