The minimum distance between this equipment and any other objects in or near the working area should be 1ft.
Good ventilation is of critical importance for the normal performance and service life of this equipment.
2.2 Thermal Overload protection.
Should the machine be used to an excessive level, or in high temperature environment, poorly ventilated area or
if the fan malfunctions the Thermal Overload Switch will be activated and the machine will cease to operate.
Under this circumstance, leave the machine switched on to keep the built-in fan working to bring down the
temperature inside the equipment. The machine will be ready for use again when the internal temperature
reaches safe level.
2.3 Over-Voltage Supply
Regarding the power supply voltage range of the machine, please refer to “Main parameter” table.
This equipment is of automatic voltage compensation, which enables the maintaining of the voltage range within
the given range. In case that the voltage of input power supply amperage exceeds the stipulated value, it is
possible to cause damage to the components of this equipment. Please ensure your primary power supply is
correct.
2.4 Do not come into contact with the output terminals while the machine is in operation. An
electric shock may possibly occur.
3. Maintenance
Exposure to extremely dusty, damp, or corrosive air is damaging to the welding machine. In order to prevent any
possible failure or fault of this welding equipment, clean the dust at regular intervals with clean and dry
compressed air of required pressure.
Please note that: lack of maintenance can result in the cancellation of the guarantee; the guarantee of this welding
equipment will be void if the machine has been modified, attempt to take apart the machine or open the
factory-made sealing of the machine without the consent of an authorized representative of the manufacturer.
4. Trouble shooting
Caution: Only qualified technicians are authorized to undertake the repair of this Plasma cutter equipment. For your
safety and to avoid Electrical Shock, please observe all safety notes and precautions detailed in this manual.

5. How a plasma cutter works
Basic plasma cutters use electricity to superheat air into plasma (the 4th state of matter), which is then blown through
the metal to be cut. Plasma cutters require a compressed air supply and AC power to operate.
6. Operation
1. When the trigger is squeezed, DC current flows through the torch lead into the nozzle.
2. Next, compressed air flows through the torch head, through the air diffuser that spirals the air flow around the
electrode and through the hole of the cutting nozzle.
3. A fixed gap is established between the electrode and the nozzle. (The power supply increases voltage in order to
