CAUTION

A procedure which, if not properly followed, may cause damage to the equipment.

W ARNING

A procedure which, if not properly followed, may cause injury to the operator or others in the operating area.

1.02 Important Safety Precautions

• 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 processes. Y ou 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.

WARNING

OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS TO YOUR HEALTH.

To prevent possible injury, read, understand and follow all warnings, safety precautions and instructions before using the equipment. Call 1-603298-5711 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.

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.”

• W ear 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.

Air supply must be free of oil, moisture, and other contaminants. Excessive oil and moisture may cause double-arcing, rapid tip wear, or even complete torch failure. Contaminants may cause poor cutting performance and rapid electrode wear.

To test the quality of air, place a welding filter lens in front of the torch and turn on the gas. Any oil or moisture in the air will be visible on the lens. Do not initiate an arc!

An air line filter, capable of filtering to at least 5 microns, is required when using air from a compressor to insure that moisture and debris from the supply hose does not enter the torch.

The rear panel of the power supply is equipped with a female 1/4 NPT gas input fitting.

Using High Pressure

Gas Cylinders

NOTE

Using Shop Air

CAUTION

To use air or nitrogen from a high pressure gas cylinder:

1. Examine the cylinder valves to be sure they are clean and free of oil, grease or any foreign material. Momentarily open each cylinder valve to blow out any dust which may be present.

2. Each cylinder must be equipped with an adjustable highpressure regulator capable of pressures up to 75 psi (5.3 BAR) minimum and flows of up to 200 scfh (94 lpm).

3. Set the tank regulator to 75 psi (5.3 BAR). Use the regulator on the front of the power supply to adjust the gas pressure to the unit.

Refer to the manufacturer's specifications for installation and maintenance procedures for high pressure gas regulators.

Do not use an air line filter with high pressure gas cylinders.

CAUTION

Replacing Filter

Cartridge

NOTE

1. Install an air filter assembly to the gas input fitting on the front panel of the power supply. The air filter is supplied with 1/4 NPT gas couplings. A quick disconnect fitting is recommended on the filter body cap to allow easy connection to the compressed air source.

2. Connect the air supply hose to the inlet fitting on the air filter body cap.

When connecting a gas fitting to the filter cap, hold the cap flats with a wrench. Over tightening the cap on the filter body can damage the filter cartridge or cap gasket.

Air filter cartridge (Part No. 7-0252) should be replaced every 30 days, depending on the condition of the compressed air. If a noticeable drop in air pressure occurs, the filter has become filled with contaminants and must be replaced.

To replace cartridge, unscrew filter cap from body, slide out old cartridge and insert new filter element. The filter cartridge fits only one way. Filter cap must be hand tight only.

Supply hoses must be at least #4 hose (1/4 in or 6.4 mm minimum inside diameter).

4.03 OPERATING THE SYSTEM

WARNING

CAUTION

NOTE

Piloting

Torch Standoff

Disconnect primary power at the source before disassembling the power supply, torch, or torch leads.

Frequently review the Important Safety Precautions at the front of this Manual. Be sure the operator is equipped with proper gloves, clothing, eye and ear protection. Make sure no part of the operator’s body comes into contact with the workpiece while the torch is activated.

Sparks from the cutting process can cause damage to coated, painted, and other surfaces such as glass, plastic and metal.

Handle torch leads with care and protect them from damage.

Piloting is harder on parts life than actual cutting because the pilot arc is directed from the electrode to the tip rather than to a workpiece. Whenever possible, avoid excessive pilot arc time to improve parts life.

Improper standoff (the distance between the torch tip and workpiece) can adversely affect tip life as well as shield cup life. Standoff may also significantly affect the bevel angle. Reducing standoff will generally result in a more square cut.

Edge Starting

Direction of Cut

Dross

For edge starts, hold the torch perpendicular to the workpiece with the front of the tip on the edge of the workpiece at the point where the cut is to start. When starting at the edge of the plate, do not pause at the edge and force the arc to "reach" for the edge of the metal. Establish the cutting arc as quickly as possible.

In the torch, the plasma gas stream swirls as it leaves the torch to maintain a smooth column of gas. This swirl effect results in one side of a cut being more square than the other. Viewed along the direction of travel, the right side of the cut is more square than the left. To make a square-edged cut along an inside diameter of a circle, the torch should move counter clockwise around the circle. To keep the square edge along an outside diameter cut, the torch should travel in a clockwise direction.

On carbon steel, dross on top of the plate is normally caused by a fast torch travel speed or a high torch standoff. This dross is usually hard to remove. Dross along the cut line on the bottom of the plate is more easily removed and is often caused by torch travel speeds that are to slow.

4.04 OPERATING WITH A HAND TORCH

Cutting with a

Hand Torch

1. The torch can be comfortably held in one hand or steadied with two hands. Choose the technique that feels most comfortable and allows good control and movement. Position the index finger or thumb to press the control switch on the torch handle.

2. For edge starts, hold the torch perpendicular to the workpiece with the front of the tip on the edge of the workpiece at the point where the cut is to start. For piercing, angle the torch slightly to direct sparks away from the torch until the pierce is complete.

3. For drag cuts keep the torch in contact with the workpiece. For standoff cutting, hold the torch 1/16 -1/8 in (2-3 mm) from the work.

4. With the torch in starting position, press and hold the control switch. After an initial gas purge, the pilot arc will come on and remain on until the cutting arc starts.

5. Once on, the main arc remains on as long as the control switch is held down, unless the torch is withdrawn from the work or torch motion is too slow. If the cutting arc is interrupted, the pilot arc comes back on automatically.

6. To shut off the torch simply release the control switch. When the switch is released a ten second post-flow will occur. If the torch switch is closed during the post-flow, the cutting arc will restart immediately when the torch is brought within range of the workpiece.

Piercing with a

Hand Torch

Manual 0-2450 19 OPERA TION

1. When piercing with a hand torch, tip the torch slightly so that blowback particles blow away from the torch tip (and operator) rather than directly back into it.

2. Complete the pierce off the cutting line and then continue the cut onto the line. Hold the torch perpendicular to the workpiece after the pierce is complete.

3. Clean spatter and scale from the shield cup and the tip as soon as possible. Spraying or dipping the shield cup in antispatter compound will minimize the amount of scale which adheres to it.

4.05 RECOMMENDED CUTTING SPEEDS
