SAFETY
IMPORTANT: BEFORE INSTALLING, OPERATING OR CARRYING OUT
MAINTENANCE ON THE PLASMA CUTTER, READ THE CONTENTS OF THIS
MANUAL CAREFULLY, WHICH MUST BE STORED IN A PLACE FAMILIAR TO ALL
USERS FOR THE ENTIRE OPERATIVE LIFE-SPAN OF THE MACHINE.
PAY PARTICULAR ATTENTION TO THE SAFETY RULES.
THIS EQUIPMENT MUST BE USED SOLELY FOR PLASMA CUTTING.
Electric shock: It can kill. Touching live electrical parts can cause fatal shocks or severe
burns. The plasma nozzle and work circuit is electrically live whenever the output is on.
The input power circuit and internal machine circuits are also live when power is on.
Do not touch live electrical parts or electrodes with bare skin, gloves or wet clothing.
Incorrectly installed or improperly grounded equipment is dangerous.
• Connect the primary input cable according to American standards and regulations. ANSI Z49.1.
• Disconnect power source before performing any service or repairs.
• Avoid all contact with live electrical parts of the welding circuit, torch nozzle and work piece with bare
hands. The operator must wear dry welding gloves while he/she performs the plasma cutting task.
• Isolate yourselves from both the earth and the work piece.
• Keep cords dry, free of oil and grease, and protected from hot metal and sparks.
• Frequently inspect input power cable for wear and tear, replace the cable immediately if damaged,
bare wiring is dangerous and can kill.
• Do not use damaged, under sized, or badly joined cables.
• Do not drape cables over your body.
• We recommend (RCD) safety switch is used with this equipment to detect any leakage of current to earth.
Fumes and gases are dangerous. Plasma cutting produces fumes and gases. Harmful
fumes and metallic powders are produced during the cutting operation. Metals which are
painted or coated or which contain mercury, zinc, lead and graphite may produce harmful
concentrations of toxic fumes during cutting. Breathing these fumes and gases can be
hazardous to your health.
•Do not breathe the smoke and gas generated whilst welding or cutting, keep your head out of the fumes
• Keep the working area well ventilated, use fume extraction or ventilation to remove welding fumes and
gases.
• In conned or heavy fume environments always wear an approved air-supplied respirator.
Cutting fumes and gases can displace air and lower the oxygen level causing injury or death.
Be sure the breathing air is safe.
• Do not cut in locations near de-greasing, cleaning, or spraying operations. The heat and rays of the arc
can react with vapours to form highly toxic and irritating gases.
• Materials such as galvanized, lead, or cadmium plated steel, containing elements that can give off toxic
fumes when cuttung. Do not cut these materials unless the area is very well ventilated, and or wearing
an air supplied respirator.
• Always read the Material Safety Data Sheets (MSDS) that should be supplied with the material you are
using.These MSDSs will give you the information regarding the kind and amount of fumes and gases that
may be dangerous to your health.
MACHINE OPERATING SAFETY
Plasma cutting equipment can be dangerous to both the operator and people in or near the surrounding
working area, if the equipment is not correctly operated. Equipment must only be used under the strict and
comprehensive observance of all relevant safety regulations. Read and understand this instruction manual
carefully before the installation and operation of this equipment.

Fire hazard. Plasma cutting on closed containers, such as tanks,drums, or pipes, can cause them to
explode. Flying sparks from the welding arc, hot work piece, and hot equipment can cause res and burns.
Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or re. Check
and be sure the area is safe before doing any cutting.
•The cutting sparks may cause re, therefore remove any ammable materials well away from the working
area. Cover ammable materials and containers with
approved covers if unable to be moved from the welding area.
•Do not Plasma Cut closed containers such as tanks, drums, or pipes, unless they are
properly prepared according to the required Safety Standards to insure that ammable
or toxic vapors and substances are totally removed, these can cause an explosion even
though the vessel has been “cleaned”. Vent hollow castings or containers before heating,
cutting or welding. They may explode.
• Do not cut where the atmosphere may contain ammable dust, gas, or liquid vapours (such as petrol)
•Have a re extinguisher nearby and know how to use it. Be alert that cutting sparks and hot materials
from cutting can easily go through small cracks and openings to adjacent areas. Be aware that cutting
on a ceiling, oor, bulkhead, or partition can cause re on the hidden side.
Gas Cylinders. Do not cut in the vicinity of pressurised gas cylinders or in the presence of
explosive dust, gases or fumes. Gas cylinders contain gas under high pressure. If damaged,
a cylinder can explode. Because gas cylinders are normally part of the welding process, be
sure to treat them carefully. CYLINDERS can explode if damaged.
• Protect gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open ames,
sparks, and arcs.
• Insure cylinders are held secure and upright to prevent tipping or falling over.
• Never allow the plasma nozzle or earth clamp to touch the gas cylinder, do not drape welding cables
over the cylinder.
• Never plasma cut on a pressurised gas cylinder, it will explode and kill you.
• Open the cylinder valve slowly and turn your face away from the cylinder outlet valve and gas regulator.
Electronic magnetic elds. The magnetic elds created by the high currents generated by
plasma cutting may affect the operation of pacemakers and other vital electronic medical
equipment.
•Wearers of Pacemakers and other Implanted Medical Devices should keep away.
•Implanted Medical Device wearers should consult their doctor and the device manufacturer before going
near any electric welding, cutting or heating operation.
Noise can damage hearing. Noise from some processes or equipment can damage hearing.
This machine does not directly produce noise exceeding 80dB. The plasma cutting/welding
procedure may produce noise levels beyond said limit; users must therefore implement all
precautions required by law. Wear approved ear protection if noise level is high.
Hot parts. Items being plasma cut generate and hold high heat and can cause severe burns.
Do not touch hot parts with bare hands. Allow a cooling period before working on the plasma
torch. Use insulated welding gloves and clothing to handle hot parts and prevent burns.
Arc rays: harmful to people’s eyes and skin. Arc rays from the plasma cutting process
produce intense visible and invisible ultraviolet and infrared rays that can burn eyes and skin.
Protect your eyes with welding masks or goggles tted with ltered lenses, and protect your
body with appropriate safety garments. Protect others by installing adequate shields or
curtains.
•Always wear a helmet or goggles with correct shade of lter lens and suitable protective clothing including
welding gloves, appron, leg and foot protection whilst the plasma cutting operation is performed.
•Measures should be taken to protect people in or near the surrounding working area. Use protective
screens or barriers to protect others from ash,glare and sparks; warn others not to watch the arc.

Plasma cutters work by passing an electric arc through a gas that is passing through a constricted opening. The gas
can be air, nitrogen, argon, oxygen. etc. The electric arc elevates the temperature of the gas to the point that it enters a
4th state of matter. We all are familiar with the first three: i.e., Solid, liquid, and gas. Scientists call this additional state
plasma. As the metal being cut is part of the circuit, the electrical conductivity of the plasma causes the arc to transfer to
the work. The restricted opening (nozzle) the gas passes through causes it to squeeze by 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 trying to develop a better welding process. Many improvements then led to
making this technology what it is today. Plasma cutters provide the best combination of accuracy, speed, and afford ability
for producing a variety of flat metal shapes. They can cut much finer, and faster than oxy-acetylene torches.
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.
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
maintain a constant current through the joint.) Electrons arc across the gap, ionizing and super heating the air
creating a plasma stream.
4. Finally, the regulated DC current is switched so that it no longer flows to the nozzle but instead flows from the
electrode to the work piece. Current and airflow continue until cutting is stopped.
Notes:
The nozzle and electrode require periodic replacement. The electrode has an insert of tough high conductive material
such as hafnium and cerium. This insert erodes with use, also the nozzle orifice will erode with use. Quality of the air
used is paramount to longer life of electrodes and nozzles, in short clean dry air gives longer parts life, the cleaner and
dryer the better. We recommend use of a Plasma Air Filter.
What kinds of materials can the plasma cut?
Virtually any metal can be plasma cut including steel, stainless steel, aluminium, brass, copper, etc. Any thickness from
30 gauge through 13/16" can be cut, depending on the power of the plasma cutter used.
How Does Plasma Cutting Compare to Oxy-fuel (gas) cutting?
Plasma cutting can be performed on any type of conductive metal - mild steel, aluminium and stainless are some
examples. With mild steel, operators will experience faster, thicker cuts than with alloys. Oxy-fuel cuts by burning, or
oxidizing the metal it is severing. It is therefore limited to steel and other ferrous metals which support the oxidizing
process. Metals like aluminium and stainless steel form an oxide that inhibits further oxidization, making conventional
oxy-fuel cutting impossible. Plasma cutting however does not rely on oxidation to work and thus it can cut aluminium,
stainless and any other conductive material. While different gasses can be used for plasma cutting, most people today
use compressed air for the plasma gas. In most shops, compressed air is readily available, and thus plasma does not
require fuel gas and compressed oxygen for operation. Plasma cutting is typically easier for the novice to master, and
on thinner materials, plasma cutting is much faster than oxy-fuel cutting. However, for heavy sections of steel (1" and
greater), oxy-fuel is still preferred since oxy-fuel is typically faster and, for heavier plate applications high powered plasma
machines are required for plasma cutting applications.
What are the limitations to Plasma Cutting? Where is Oxyfuel preferred?
The plasma cutting machines are typically more expensive than oxy/acetylene. Also, oxy/acetylene does not require
access to electrical power or compressed air which may make it a more convenient method for some users. Oxyfuel can
generally cut thicker sections (>63/64 inch) of steel more quickly than plasma
