Determining the Thickness of The Metal
Thickness is one of the most important features that the operator should
determine. Before using the cutter, it is important to measure the thickness of the
metal that needs to be cut. Plasma cutting machine depends on the material that
you choose for cutting. Take for instance; a 375 spectrum plasma machine can
effectively cut 3/8 inches of steel.
In addition, you can also use a powermax plasma cutter that can help you cut a
metal sheet 55 mm (2-1/4"). Also, select a compatible system with interface
options for automation equipment like a CNC table, robot and track cutters.
Plasma machine works best on conductive metal including mild steel, aluminum,
copper, stainless steel, etc. If you have ample of knowledge and a bit of practice,
you can achieve smooth, clean, and consistent gouges. This machine also helps in
reducing the amount of noise and debris created in the environment.

oxidizing but it does not rely on oxidization to operate.
This plasma machine comes in a variety of shapes and sizes and provides the
cutting speed for the thickness of the metal measured in inches per minute (IPM).
You should choose a machine that handles twice the normal thickness
approximately twice your normal cutting thickness.
Take for instance; to perform long, fast, quality production cuts on ¼" steel choose
a 1/2" class (60 amps) machine.

Machines Working Quality
The plasma cutting technology has been increasingly improving for about 30 years and
more and continues to do so. The quality of the equipment is better than the manual
process of cutting. With the help of this advanced technology, you can easily cut a
workpiece and create different designs.
The working quality of the machine depends on the cut quality on metal. The better is
the quality on the metal, the effective is the tool. Therefore, it is very important to
consider a few factors like type of the machine, plasma cutting system, motion control
devices, process variables, and external variables while attempting to improve the
appearance of the cut.
While operating the CNC plasma machine, ensure that your follow appropriate
specifications along with correct process for metal type, metal thickness, the quality of
the cut, and productivity goals. Also, ensure that the plasma arc cutting is at an
appropriate direction and correct process is selected for cutting the material.

6.
What is a Plasma Cutter?
Plasma CNC cutter is a process that cuts through the electrically conductive material
with the help of hot plasma. Plasma cutting machines use a high-velocity jet of ionized
gas that is delivered from the orifice. Plasma conducts electricity from the torch of the
plasma cutter to the workpiece and heats the object, thereby melting the material.
In simplest term, plasma machine can be used in various types of conductive metals
such as mild steel, aluminum and stainless. It is ideal for non-ferrous materials that are
less than 1 inch thicker. OMNI CNC plasma cutting machines are good at smooth
cutting edges of the material giving clean and precise cut. Products are ideally suited
for automotive fabrication, structural steel cutting, construction, sign shops, metal
fabrication, decorative fencing.

Software Used to Operate the Plasma Cutter
The software that comes with the plasma cutter is indubitably one of the most
important parts of the machine. It allows the operator to successfully design, cut, and
control the operation of the plasma torch.
To create top quality designs with the plasma cutter, the operator must use AutoCAD
for the CAD part and EXG Code for the CAM portion. The software that actually
controls the plasma usually comes along with the CNC plasma table.
CNC plasma cutting software STARCAM is very easy to operate. It consists of 3
modules, first drawing module (StarCAD), nesting module, (StarCUT), and numerical
control emulation module (StarTEST).
A short training is also given to the new user to make comprehend with the basics of a
4*8 plasma cutting machine. If you are interested in seeing the work process of this
machine, you must read plasma machine software in action.

9.
How CNC Plasma Cutting Evolved?
Plasma cutting machines have come a long way. It has evolved to a great extent
and considered as one of the most effective productive equipment for cutting
metal sheets and plates.
The plasma machine has greater flexibility and ability to cut diverse shaped
materials on the basis of the instructions programmed.
The machines were generally limited to cutting various patterns using X and Y axis
of motion.

Maintenance Tips
Neglecting the maintenance of the plasma CNC table would cause damage to the
machine. The mechanical parts of the machine will wear causing abrasion.
When the components of the machinery fail, troubleshooting or maintenance of
the machine is a must thereby preventing any type of hazards.
Here are some maintenance tips that you should consider preventing injuries and
any sort of fatalities that may occur if the machine is not properly maintained.

11.
Check the Torch Body
Remove the parts of the torch and clean inner parts of the torch with cotton
dabbed in the cleaner. Separate the torch from its mounting tube and slide it back.
Also, ensure that the torch body has no leaks or damage to any of the connections.
Clean the Torch Leads
Wipe out the torch leads and remove the metal dust and dirt that is accumulated in
the torch leads. The metal dust can cause dissipation of the high voltage needed to
start the plasma arc. Also, check kinked or worn hoses, exposed wires, and
damaged fittings that can be a reason for injuries and fatalities.

12.
Clean the Power Supply
Clear accumulated metal dust with the help of clean, dry, shop air. Metal dust can
cause damage to power-supply components, especially PC boards. Moreover,
contractors, relays, and spark-gap assemblies can also malfunction due to excessive
formation of metal dust. Ensure that the air filters are clean so that the power supply
is not hindered.
Check Torch Cooling Components
Check the coolant stream in the tank for signs of aspirated air or reduced flow.
Check that flow switches and ensure the return flow functions properly. Insufficient
flow of the coolant can cause the torch to overheat. Check the coolant filters, pump
screens, and clean/replace them as per the situation.

13.
Align and Adjust Gears and Bearings
Adjust and align gears of the CNC plasma cutting machine for sale so that the gears
do not overlap the rack. Ensure that the adjustments are made properly for rail and
