1.02 Important Safety Precautions

WARNINGS
OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN BE DAN­GEROUS AND HAZARDOUS TO YOUR HEALTH.
Plasma arc cutting produces intense electric and magnetic emissions that may interfere with the proper function of cardiac pacemakers, hearing aids, or other electronic health equipment. Per­sons who work near plasma arc cutting applica­tions should consult their medical health profes­sional and the manufacturer of the health equipment to determine whether a hazard exists.
To prevent possible injury, read, understand and follow all warnings, safety precautions and in­structions before using the equipment. Call 1-603­298-571 1 or your local distributor if you have any questions.
GASES AND FUMES
Gases and fumes produced during the plasma cutting process can be dangerous and hazardous to your health.
• Keep all fumes and gases from the breathing area. Keep your head out of the welding fume plume.
• Use an air-supplied respirator if ventilation is not adequate to remove all fumes and gases.
• The kinds of fumes and gases from the plasma arc depend on the kind of metal being used, coatings on the metal, and the different pr ocesses. You must be very careful when cutting or welding any met­als which may contain one or more of the follow­ing:
Antimony Chromium Mercury Arsenic Cobalt Nickel Barium Copper Selenium Beryllium Lead Silver Cadmium Manganese Vanadium
• 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.
• For information on how to test for fumes and gases in your workplace, refer to item 1 in Subsection 1.03, Publications in this manual.
• Use special equipment, such as water or down draft cutting tables, to capture fumes and gases.
• Do not use the plasma torch in an area where com­bustible or explosive gases or materials are located.
• Phosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers. Remove all sources of these vapors.
• This product, when used for welding or cutting, produces fumes or gases which contain chemicals known to the State of California to cause birth de­fects and, in some cases, cancer . (California Health & Safety Code Sec. 25249.5 et seq.)
ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process uses and produces high voltage electrical energy. This electric energy can cause severe or fatal shock to the op­erator or others in the workplace.
• Never touch any parts that are electrically “live” or “hot.”
Date: May 1, 2000 1-1 GENERAL INFORMATION
• Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the welding circuit.
• Repair or replace all worn or damaged parts.
• Extra care must be taken when the workplace is moist or damp.
• Install and maintain equipment according to NEC code, refer to item 9 in Subsection 1.03, Publica­tions.
• Disconnect power source before performing any service or repairs.
• Read and follow all the instructions in the Operat­ing Manual.
FIRE AND EXPLOSION
Fire and explosion can be caused by hot slag, sparks, or the plasma arc.
• Be sure there is no combustible or flammable ma­terial in the workplace. Any material that cannot be removed must be protected.
• Ventilate all flammable or explosive vapors from the workplace.
• Do not cut or weld on containers that may have held combustibles.
• Provide a fire watch when working in an area where fire hazards may exist.
• Hydrogen gas may be formed and trapped under aluminum workpieces when they are cut under­water or while using a water table. DO NOT cut aluminum alloys underwater or on a water table unless the hydrogen gas can be eliminated or dis­sipated. Trapped hydrogen gas that is ignited will cause an explosion.
NOISE
Noise can cause permanent hearing loss. Plasma arc pro­cesses can cause noise levels to exceed safe limits. You must protect your ears from loud noise to prevent per­manent loss of hearing.
• T o protect your hearing fr om loud noise, wear pro­tective ear plugs and/or ear muffs. Protect others in the workplace.
• Noise levels should be measured to be sure the deci­bels (sound) do not exceed safe levels.
• For information on how to test for noise, see item 1 in Subsection 1.03, Publications, in this manual.
PLASMA ARC RAYS
Plasma Arc Rays can injur e your eyes and burn your skin. The plasma arc process produces very bright ultra violet and infra red light. These arc rays will damage your eyes and burn your skin if you are not properly pr otected.
• To protect your eyes, always wear a welding hel­met or shield. Also always wear safety glasses with side shields, goggles or other protective eye wear.
• Wear welding gloves and suitable clothing to pro­tect your skin from the arc rays and sparks.
• Keep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or dirty.
• Protect others in the work area from the arc rays. Use protective booths, screens or shields.
• Use the shade of lens as suggested in the following per ANSI/ASC Z49.1:
Minimum Protective Suggested
Arc Current Shade No. Shade No.
Less Than 300* 8 9
300 - 400* 9 12 400 - 800* 10 14
* These values apply where the actual arc is clearly seen. Experience has shown that lighter filters may be used when the arc is hidden by the work­piece.

Manual 0-2865 2-3 INTRODUCTION & DESCRIPTION

2.05 Theory Of Operation

A. Plasma Arc Cutting and Gouging
Plasma is a gas which is heated to an extremely high tem­perature and ionized so that it becomes electrically con­ductive. The plasma arc cutting process uses this plasma gas to transfer an electric arc to a workpiece. The metal to be cut is melted by the intense heat of the arc and then blown away by the flow of gas.
With a simple change of torch parts, the system can also be used for plasma arc gouging. Plasma arc gouging uses the same process to remove material to a controlled depth and width.
B. Input and Output Power
The unit converts AC input power to DC power for the main cutting arc. The negative output is connected to the torch electrode through the negative torch lead, and the positive output connects to the workpiece through the work cable.
C. Pilot Arc
When the torch is activated there is a 2 second (service adjustable) gas pre-flow, followed by an uninterrupted pulsed DC pilot arc established between the electrode and tip. The pilot arc is initiated by a momentary high fre­quency pulse from the Power Supply. The pilot creates a path for the main arc to transfer to the work. When the main arc is established, the pilot arc shuts off. The pilot automatically restarts when the main arc stops, as long as the torch remains activated.
1. Parts-In-Place (PIP) Interlock
The Power Supply has a built-in parts-in-place in­terlock that prevents accidental torch starting when torch parts are not properly installed. A flow switch on the coolant return lead detects reduced coolant flow caused by improper torch assembly. If not satisfied, the switch interrupts power to the tip and electrode.
2. Gas Pressure Interlock
A pressure switch acts as an interlock for the plasma gas supply . If the plasma gas supply pr es­sure falls below minimum requirements the pr es­sure switch will open, shutting off the power to the contactors, and the GAS indicator will go out. When adequate plasma supply pressure is avail­able the pressure switch will close, allowing power to be resumed for cutting.
NOTE
There is no gas pressure interlock for secondary gas.
D. Main Cutting Arc
The power supply converts the AC input power to DC power for the main cutting arc. The negative output is connected to the torch electrode through the negative torch lead. The positive output is connected to the work­piece via the work cable and clamp connection.
E. RF Shielding
Machine torch systems using CNC Interface Cables are shielded to minimize radio frequency (RF) interference which results from the high frequency ar c initiation. These shielded systems are designed with features such as a wire for establishing an earth ground and shielded torch and control leads. The CNC control signals are filtered on an internal PC Board.
F. Interlocks
The system has several built-in interlocks to provide safe and efficient operation. When an interlock shuts down the system, the fault condition must be remedied and the system recycled using the applicable control device.
