Inverter
Technology
This device uses single tube IGBT inverter technology (the inverter frequency range is from
25-50KHz) to convert 50/60Hz alternating current (AC) to direct current (DC) and then to high
frequency and lower voltage rectification. The resulting pulse width modulation (PWM) output can
be used for the high-power DC power supply, Due to switching power inverter technology adopted,
the weight of the welder has been significantly decreased and the conversion efficiency of the whole
machine is increased by more than 30%.
Wide Voltage Our cutting machine is equipped with a power supply voltage compensation device，The power
supply voltage will work when the rated voltage is within 15% of requirements. When using
extension cords, in order to reduce voltage drop, use a heavy duty extension cord (10 or 12AWG or
greater) or use the recommended configuration length.

3.3.3 Cutting performance
1 Amperage Standard rule of thumb is the thicker the material the more amperage required. On thick material, set
the machine to full output and vary your travel speed. On thinner material, you need to turn down the
amperage and change to a lower-amperage tip to maintain a narrow kerf. The kerf is the width of the
cut material that is removed during cutting.
2 Speed Amperage and speed are critical to producing a good quality cut. visually follow the arc that is coming
from the bottom of the cut. The arc should exit the material at a slight angle away from the direction of
travel. If it's going straight down, that means the speed is too slow, and IT will have an unnecessary
buildup of dross or slag. If the speed is too fast, it will start spraying back onto the surface of the
materia without cutting the workpiece completely. Because the arc trails at an angle, at the end of a
cut, slow your cutting speed and angle the torch in to cut through the last bit of metal.
3 Direction It is easier to pull the torch towards you than push it. The plasma stream swirls as it exits the tip, biting
one side and finishing off on the other leaving a bevelled edge and a straight edge. The bevel cut effect
is more noticeable on thicker material and needs to taken into consideration before starting your cut as
you want the straight side of the cut to be on the finished piece you keep.
4 Torch tip
height &
position
The distance and position of the plasma torch cutting tip has an affect on the quality of the cut and the
extent of the bevel of the cut. The easiest way to reduce bevel is by cutting at the proper speed and
height for the material and amperage that is being cut.
5 Tip size
and
condition
The tip orifices focus the plasma stream to the work piece. It is important to use the correct size tip for
the amperage being used,for example a tip with a 3/64" orifice is good for 0-40 amps whereas a 1/16"
orifice is better for 40-80 amps.
The low-amp tip has a smaller orifice which maintains a narrow plasma stream at lower settings for use
on thin-gauge material. Using a 25 amp tip at an 60 amp setting will blow out and distort the tip orifice
and require replacement.
Conversely, using an 80-amp tip on the lower settings will not allow you to focus the plasma stream as
well and creates a wide kerf.The condition of the tip orifice is critical to the quality of the cut result, a
worn or damaged tip orifice will produce a distorted plasma stream resulting in a poor cut quality.
6 Electrode
condition
A fixed gap is established between the electrode and the inside of the cutting tip. Electrons arc across
the gap, ionizing and super heating the air creating the plasma stream. The electrode contains an
insert in the end made of a highly conductive material called hafnium. This insert erodes with use and
develops a pit in the end of the electrode, when the pit becomes too much poor quality cuts will result
and necessitate replacement of the electrode.
7 Air quality,
Air
pressure
and
volume
Compressors take in air at atmospheric pressure and increase the pressure and store it in a tank.
Moisture that forms in air lines has a tendency to condense into larger drops when the air pressure
decreases as it is entering the plasma torch. When these droplets enter into the high temperatures in
the plenum of the torch, they immediately break down into oxygen and hydrogen, which alters the
normal chemical content of air in the torch. These elements will then dramatically change the plasma
arc which causes the torch consumable parts to wear very quickly, alters the shape of the nozzle
orifice, dramatically affecting cut quality in terms of edge squareness, dross formation, and edge
smoothness.Air pressure, flow rate and air quality are critical to quality plasma cutting and consumable
life span.Usually air pressure is preset at 60 psi . The volume capacity of your compressor is important,
If you are doing a lot of cutting, cutting thick plate (same air consumption but slower cut speeds =
longer cut time) then choose a compressor at 1.5 to 2 times the plasma system requirement.

①The correct torch height and right angle shall be consistent with the minimum slope and equal slope of the material, so
as to ensure good cutting effect and prolong the service life of consumables.
②Torch angled to the material unequal bevel, one side may be excessively beveled.
③Torch height too high, plasma stream may not cut all the way through the material.
④Torch height too low. Tip may contact the work piece and short out or damage the tip.
Speed and Amperage
Touch No Touch
1
When cutting, select the appropriate current and pushing speed according to the material and thickness of the workpiece
to ensure that the spark are exiting from the bottom of the workpiece
2
If the spark comes out from the top of the workpiece, it means that the workpiece has not been completely cut, because
the torch moves too fast or the current is set too low.
3
If the spark passes vertically through the workpiece, it indicates that the workpiece has been completely cut off and the
torch is cutting air because the torch moves too slowly or the current setting is too large

6 Attention
The safety notes listed in this manual is to ensure correct use of the machine and to keep you and other people from being
hurt.
The design and manufacture of cutting machine considers safety. Please refer to the safety warning listed in the manual to
avoid accidents.
Different damage would be caused by wrong operation of the equipment as follows. Please read the user manual carefully
to reduce such damage.
6.1 Cutting environment and safety
Working surroundings
(1) Cutting should be carried out in dry surroundings. The air humidity level should not be higher than 90%.
(2) The temperature should be between -10C to 40C.
(3) Don’t use the cutting machines in sunshine or rain. Keep it off water.
(4) Don't use the machines in the places of dust or corrosive air.
(5) Cutter machine should not be carried out in places with quick air flow.
Safety norms
Protection circuit of over-voltage, over-current and over-heat circuits are designed in the cutting machines. It will stop
working automatically when the input voltage, output current or internal temperature exceed the rated value. But if the
machines are excessively used, such as with input voltage higher than the rated, the machine might be damage. Please
pay close attention to the following matters.
Keep good ventilation!！
The cutting machines work with high cutting voltage. Nature air flow can’t reach the requirement of heat dissipation. So
the fans are installed as cooling system to ensure stable performance.
Make sure the ventilation windows are not covered or blocked. The distance between the machines and things around
should not be less than 0.3m. Good ventilation is good for cutting performance and operational life.
Never over load!
Check the maximum rated current (according to the Duty Cycle chosen). Make sure the cutting current is never higher
than the rated value. Over current running will obviously shorten the operation life, even damage the machine.
Never over voltage!
The Input Voltage could be found in Technical data diagram. The auto-compensation function will keep the cutting current
in the rated range. If the input voltage exceed the permissible value, the machine would be damaged. Users should take
protective measures in advance to avoid it.
Make sure earth connected before operation.
On the rear panel of cutting machine, a screw for earth connecting would be found. It must be ground connected with
cable whose section is bigger than 6mm2 before operation, to avoid accidents caused by static or electricity leak.
