INTRODUCTION
FUNCTIONAL DIAGRAM
CUT-50/CUT50P Air plasma cutting technology.Plasma cutters work by passing an electric arc through air/gas
which is passing through the narrow opening. The gas can be air, nitrogen, argon, oxygen, and etc. The electric
arc elevates the temperature of the gas to the point that make it enters a 4th state of matter. We all are familiar
with the rst three state: solid, liquid, and gas. Scientists call the fouh state plasma. As the metal being cut is
pa of the circuit, the electrical conductivity of the plasma causes the arc to be transferred to the work.
The gas passes through the restricted opening (nozzle) which make it be squeezed at a high speed, like air
passing through a venturi in a carburettor. This high speed gas cuts through the molten metal.
Plasma cutting was invented as the result of ting to develop a better welding process. Many improvements
have made the technology what it is today. Plasma cutters provide the best combination of accuracy and speed,
and the ability of producing a variety of at metal shapes. They can cut much ner and faster than oxyacetylene
torches.

1. Current display meter
The digital ammeter is used to display the actual output current of the power source.
2. Power indicator light
Turn on the power, and this light will be on.
3. Fault light
When the welding load is overloaded and the output current of the machine is too large, this light will be on.
This situation is normal and the machine can recover itself. When there is damage inside the machine, this light
will be on. In this case, the machine is abnormal and requires maintenance.
4. Adjust the value knob
Clockwise rotate the knob to enlarge the current, and anti-clockwise rotate the knob to reduce the current.
5. Cutting gun cable and gas connection seat
Remove the black cap and connect the cutting gun.
6. Cutting gun control socket
That is two-core aviation socket. The cutting gun triggers switch to control connection.

CUT50 Plasma cutting machines will be subjected to various strict tests before leaving
the facto. This is for ensuring that each welding machine that reaches the user is of high
quality. Because our machines have to go through tens of thousands of kilometers of
long-distance transpoation from the facto to your hands. In this process, it’s
inevitable that some uncontrollable factors will lead to the loosening or even damage of
some components inside machine. We recommend that you check its external as soon as
you get the welder, and turn on the power to check if you have received a qualied product.
Tips:
1. Wear a welding helmet with appropriate lters to protect your face and eyes when
welding or watching.
2. Wear approved safety glasses. Side shields are recommended.
3. Use protective screens or barriers to protect others from ash and bright lights and
warn others not to watch the arc.
4. Wear protective clothing made from durable, ame-resistant material (wool and
leather) and foot protection.
5. If there is too much noise, use approved earplugs or earmus.
MACHINE OPERATION GUIDANCE
SIMPLE TEST FOR POWERING ON THE MACHINE
1. Please make sure your power supply voltage is 110V±10%/ 220V±10%.
2. It is recommended to choose 50A circuit breaker protection.
3. Please choose the power plug that suits your local electrical law requirements for
this machine.
4. Extension cord: Choose #12 AWG or larger one; choose 25’ (8m) or shoer one.
2 PRECAUTIONS FOR POWER-ON INSPECTION:

OPERATION
Note:
1. Normal phenomena: The digital display shows irregular changes at the beginning,
and then returns to the digital display after 3 seconds.
2. In order to reduce the working temperature of the machine, the inside fan would
continue to rotate for a few seconds after the power is turned o.
3. Normal phenomena: Machine protection may occur during high strength continuous
welding. After continuous heat dissipation, the machine would return to normal state.
Attached table:
Self-examination of abnormal conditions when turning on the machine:
1. The machine's power switch is not turned on.
2. The power input voltage is wrong.
3. The power plug is loose.
4. The internal circuit is loose (due to long-distance transpoation, bumps),
and you need to open the cover and check the internal connection.
CUT mode
If you want to cut any metal objects, please use this plasma cutting machine.
Turn on the power switch of the machine, and the fan on the back of the machine rotates,
and the digital display on the panel indicates that the power is normal.
