FLASH HAZARDS

FIRE HAZARDS

ARC RAYS CAN INJURE EYES AND BURN SKIN! To reduce risk of injury from arc rays, read, understand, and follow the following safety instructions. In addition, make certain that anyone else that uses this welding equipment, or is a bystander in the welding area, understands and follows these safety instructions as well. NEVER look at an electric arc without proper protection. A welding arc is extremely bright and intense and, with inadequate or no eye protection, the retina can be burned, leaving a permanent dark spot in the field of vision. A shield or helmet with a number 10 shade filter lens (minimum) must be used. NEVER strike a welding arc until all bystanders and you (the welder) have welding shields and/or helmets in place. NEVER wear a cracked or broken helmet and replace any cracked or broken filter lenses IMMEDIATELY. NEVER allow the uninsulated portion of the electrode holder to touch the ground clamp or grounded work to prevent an arc flash from being created on contact. ALWAYS provide bystanders with shields or helmets fitted with a #10 shade filter lens. ALWAYS wear protective clothing. The intense light of the welding arc can burn the skin in much the same way as the sun, even through light-weight clothing. Wear dark clothing of heavy material. The shirt worn should be long sleeved and the collar kept buttoned to protect chest and neck. ALWAYS protect against REFLECTED ARC RAYS. Arc rays can be reflected off shiny surfaces such as a glossy painted surface, aluminum, stainless steel, and glass. It is possible for your eyes to be injured by reflected arc rays even when wearing a protective helmet or shield. If welding with a reflective surface behind you, arc rays can “bounce off” the surface, then off the filter lens on the inside of your helmet or shield, then into your eyes. If a reflective background exists in your welding area, either remove it or cover it with something nonflammable and non-reflective. Reflected arc rays can also cause skin burn in addition to eye injury.

FIRE OR EXPLOSION CAN CAUSE DEATH, INJURY, AND PROPERTY DAMAGE! To reduce risk of death, injury, or property damage from fire or explosion, read, understand, and follow the following safety instructions. In addition, make certain that anyone else that uses this welding equipment, or is a bystander in the welding area, understand and follow these safety instructions as well. REMEMBER! Arc welding by nature produces sparks, hot spatter, molten metal drops, hot slag, and hot metal parts which can start fires, burn skin and damage eyes. NEVER wear gloves or other clothing that contain oil, grease, or other flammable substances. NEVER wear flammable hair preparations. NEVER weld in an area until it has been checked and cleared of combustible and/or flammable materials. BE AWARE that sparks and slag can fly 35 feet and can pass through small cracks and openings. If work and combustibles cannot be separated by a minimum of 35 feet, protect against ignition with suitable, snug-fitting, fire resistant covers or shields. NEVER weld on walls until checking for and removing combustibles touching the wall on the other side. NEVER weld, cut, or perform other hot work on used barrels, drums, tanks, or other containers that contained a flammable or toxic substance. The techniques for removing flammable substances and vapors in order to make a used container safe for welding or cutting are quite complex and require special education and training. NEVER strike an arc on a compressed gas or air cylinder or other pressure vessel. Doing so will create a brittle area that can result in a violent rupture immediately or at a later time as a result of rough handling. NEVER weld or cut in an area where the air may contain flammable dust (such as grain dust), gas, or liquid vapors (such as gasoline). NEVER handle hot metal, such as the work piece or electrode stubs, with bare hands. ALWAYS wear leather gloves, heavy long sleeve shirt, cuffless trousers, high-topped leather shoes, helmet, and cap. As necessary, use additional protective clothing such as leather jacket or sleeves, fire resistant leggings, or apron. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves and collars should be kept buttoned and pockets eliminated from the front.

NEVER weld in a confined area unless it is being ventilated or the operator (and anyone else in the area) 4 wearing an air-supplied respirator. NEVER bring gas cylinders into or allow gas leaks in a confined space. Leaked gas can rapidly reduce oxygen concentration levels in a confined space. ALWAYS shut off shielding gas supply at its source before leaving a confined area and check to make sure the area is safe before reentering it. ALWAYS stop welding if you develop momentary eye, nose, or throat irritation as this indicates inadequate ventilation. Stop work and take necessary steps to improve ventilation in the welding area. Do not resume welding if physical discomfort persists.

ALWAYS have a fire extinguishing equipment handy for instant use! A portable chemical fire extinguisher, type ABC, is recommended. ALWAYS wear ear plugs when welding overhead to prevent spatter or slag from falling into ear. ALWAYS make sure welding area has a good, solid, safe floor, preferably concrete or masonry, not tiled, carpeted, or made of any other flammable material. ALWAYS protect flammable walls, ceilings, and floors with heat resistant covers or shields. ALWAYS check welding area to make sure it is free of sparks, glowing metal or slag, and flames before leaving the welding area.

FUME HAZARDS

COMPRESSED GASSES AND EQUIPMENT HAZARDS

FUMES, GASSES, AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS, AND DEATH! To reduce risk of discomfort, illness, or death, read, understand, and follow the following safety instructions. In addition, make certain that anyone else that uses this welding equipment or is a bystander in the welding area, understands and follows these safety instructions as well. NEVER weld in an area until it has been checked for adequate ventilation as described in ANSI standard #Z49.1. If ventilation is not adequate to exchange all fumes and gasses generated during the welding process with fresh air, do not weld unless you (the welder) and all bystanders are wearing air-supplied respirators. NEVER heat metals coated with or containing materials that produce toxic fumes, such as galvanized steel, unless the coating is removed, the area is well ventilated, or the operator and all bystanders wear air-supplied respirators. NEVER weld, cut, or heat lead, zinc, cadmium, mercury, beryllium, or similar metals without seeking professional advise and inspection of the ventilation of the welding area. These metals produce EXTREMELY TOXIC fumes which can cause discomfort, illness, and death. NEVER weld or cut in areas that are near chlorinated solvents. Vapors from chlorinated hydrocarbons, such as trichloroethylene and perchloroethylene, can be decomposed by the heat of an electric arc or its ultraviolet radiation to form PHOSGENE, a HIGHLY TOXIC gas, along with other lung and eye-irritating gasses. Do not weld or cut where these solvent vapors can be drawn into the work area or where the ultraviolet radiation can penetrate to areas containing even very small amounts of these vapors.

IMPROPER HANDLING AND MAINTENANCE OF COMPRESSED GAS CYLINDERS AND REGULATORS CAN RESULT IN SERIOUS INJURY OR DEATH! To reduce risk of injury or death from compressed gasses and equipment hazards, read, understand, and follow the following safety instructions. In addition, make certain that anyone else who uses this welding equipment or is a bystander in the welding area understands and follows these safety instructions as well. NEVER use flammable gasses with TIG welders. Only inert or non-flammable gasses are suitable for TIG welding. Examples are Carbon Dioxide, Argon, Helium, etc. or mixtures of more than one of these gasses. NEVER attempt to mix gasses in or refill a cylinder yourself. NEVER expose cylinders to excessive heat, sparks, slag, and flame, etc. Cylinders exposed to temperatures above 130 degrees F. will require water spray cooling. NEVER expose cylinders to electricity of any kind. NEVER use cylinder or its contents for other than its intended use. Do not use as a support or roller. NEVER locate cylinders in passageways or work areas where they may be struck. NEVER lift cylinders off the ground by their valves or caps or with chains, slings, or magnets. NEVER use a wrench or hammer to open a cylinder valve that cannot be opened by hand. Notify your supplier.

PRODUCT DESCRIPTION DUTY CYCLE

Your High Frequency Arc Stabilizer is designed for use in either AC or DC shielded metal arc welding (SMAW), otherwise known as stick welding. It is also used as pan of a Tungsten Inert Gas (GTAW, TIG or Heliarc) welding setup. The High Frequency Arc Stabilizer is a supplement to the standard arc welding power supply. It consists of a spark gap type oscillator which superimposes high frequency energy onto the welding current by means of an air core coupling transformer. The secondary of the air core transformer is in series with the arc current and carries the full welding current. There are several benefits to adding high frequency to the welding output:

The duty cycle rating of a unit tells the operator how long he or she can weld and how long the unit must rest and cool. It is expressed as a percentage of 10 minutes (the industry recognized cycle time) and represents the maximum welding time allowed, with the balance of the 10 minute cycle required for cooling. The High Frequency Arc Stabilizer is rated at 20% duty cycle. NOTE: The use of a high frequency unit may require derating of the welding power supply. Consult the manufacturer of the power supply to verify the duty cycle of the power supply when used with a high frequency unit. Typically the duty cycle is reduced by 1/3rd when used in this manner.

1. The welding arc may be started without touching the electrode to the work piece. 2. Better arc stability and arc cleaning action is obtained. 3. A longer arc is possible - this is particularly useful with some types of welding rods. 4. Welding electrodes have longer life because touch starting is eliminated. 5. A wider range of welding current can be used for any specific welding electrode. 6. When used with a Tungsten Inert Gas (TIG, GTAW) Torch, aluminum and magnesium may be welded with ease.

INSTALLATION AND ASSEMBLY PROVIDE REQUIRED POWER

machine case. It may be very noticeable if the unit is not fully assembled with all cabinet screws secured or if the unit is not properly grounded. This unit is adequately shielded to prevent direct radiation of noticeable consequence assuming it is properly grounded.

POWER REQUIREMENTS DO NOT OPERATE THIS UNIT if the ACTUAL power source voltage is less than 105 volts AC or greater than 132 volts AC. Contact a qualified electrician if this problem exists. Improper performance and/or damage to the unit will result if operated on inadequate or excessive power. ELECTRIC SHOCK CAN KILL! FIRE CAN KILL, INJURE, AND CAUSE PROPERTY DAMAGE! To reduce the risk of electric shock and fire, connect only to properly grounded and fused outlets. NEVER ALTER the AC power cord or power cord plug provided on the unit. NEVER ALTER an extension cord or extension cord plugs.

2. Direct Feed-Back to Power Line High frequency energy may get into the power line by direct coupling inside the welder or the high frequency unit. The power line then acts as an antenna, emitting the high frequencies. By using proper shielding techniques given below, this can be prevented. 3. Direct Radiation from the Welding Leads Direct radiation from the welding leads, while very pronounced, decreases rapidly with distance from the leads themselves. Using as short of a welding lead set as possible, you can reduce the interference greatly. The intensity and frequency of the radiation can be altered over wide ranges by simply changing the locations and positions of the welding leads and the work. Keeping the work and ground leads close together and unlooped can help a great deal.

SPECIAL CONSIDERATIONS REGARDING HIGH FREQUENCY ENERGY Electrical equipment utilizing high frequency energy in any way is capable of radiating electrical interference. Read and follow instructions given later in this manual to make sure installation is such that interference is minimized. Wearers of heart pacemakers and other electronic equipment vital to life should check with the life support manufacturer and their physician to determine if a hazard exists. Protect hands and all body parts that may come in contact with the welding circuit. High frequency energy can cause painful burns. High frequency energy has certain undesirable characteristics which should be eliminated or minimized when welding. Any equipment utilizing high frequency energy in any way is capable of radiating interference if not properly installed. Since the high frequency unit is a basic type of radio transmitter, it may cause interference with the reception of nearby radio and television receivers as well as superimpose electronic pulses in solid state devices nearby. Therefore, protection must be provided to stop leakage of the high frequency energy as much as possible. In High Frequency Arc Stabilizer applications, interfering radiation can escape in four distinct methods:

4. Pick-Up and Radiation from Power Lines Even though welding lead radiation falls off rapidly with distance, the field strength in the immediate vicinity of the welding area may be extremely high. Unshielded wiring and ungrounded metallic objects in this strong field area may pick up the direct radiation, conduct the energy for some distance, and produce a strong interference in another area. This is usually the most troublesome source of interference, but careful adherence to the shielding and grounding instructions given below will minimize the problem.

INSTALLATION CONSIDERATIONS To minimize the effects of high frequency energy radiating out of the welding area, it is important to provide shielding to the electrical wiring and other conductive items in the welding area. A zone of approximately 50 feet around, above, and below the weld area is susceptible to high frequency generated by the unit and the arc. Listed below are guidelines in preparing the weld area and the building.

1. Direct Radiation from the Welding Machine This is radiation that escapes directly from the welding

SHIELDING AND GROUNDING THE AREA

CONNECTION TO YOUR WELDING POWER SUPPLY

All building wiring within 50 feet of the welding area should be shielded with solid metallic conduit. The use of helically wrapped metal conduit is not sufficient to effectively shield the wiring. Only solid conduit should be used and care should be taken to insure that connections at connection points of the conduit are good. A good suggestion is to use copper strap across connection points of the conduit to make the ground complete. The ground of the primary power system must be at least 8 feet into moist soil and should be connected to the shielding conduit with as short as possible of a connecting wire. When welding in a metal building, it is important that the building itself be properly grounded. Welding within a metal building does not improve or detract from the high frequency energy radiated from the weld area.

There are two leads coming from the front of the High Frequency Arc Stabilizer. These are the welding power input leads. They are placed into the mating receptacles on the front of your welding power supply. The lead marked “TO WELDER GROUND” is placed into the ground jack of the welder, the lead marked “TO WELDER OUTPUT” is placed in the output jack of the welder. When welding with DC current, select the polarity with these leads by placing the cables as shown in the following chart:

NOTE: All changes in power and lighting wiring should be made by qualified personnel only and be done in accordance with the National Electrical Code as well as any local codes and requirements.

DC Straight Polarity

DC Reverse Polarity

Connect “TO WELDER GROUND” to the Welder’s Positive Output

Connect “TO WELDER GROUND” to the Welder’s Negative Output

Connect “TO WELDER OUTPUT” to the Welder’s Negative Output

Connect “TO WELDER OUTPUT” to the Welder’s Positive Output

If your welding power supply does not have plug-in style output jacks, obtain part number 2806, Adapter Fitting Kit, to adapt your existing welder output cables for use with this unit. See your dealer for details.

CONNECT UNIT TO POWER SOURCE 1. DO NOT ALTER the AC power cord or powercord plug on this unit. Doing so may VOID THE WARRANTY. If the unit’s AC power cord plug does not mate with your existing receptacle, have an appropriate receptacle installed by a qualified electrician in accordance with the National Electrical Code and local codes and ordinances. Do not use any adapters between the unit’s AC power cord plug and AC power source receptacle.

CONNECTION OF WELDING OUTPUT LEADS Always place the electrode of the welding circuit in the output receptacle marked “TO TIG TORCH” even if not using a TIG Torch. The ground cable is always placed in the receptacle marked “TO WORK GROUND”.

2. Make sure the POWER SWITCH on the front of the unit is turned to its “OFF” position. Then plug the unit’s power cord plug into the AC power source receptacle.

MAINTENANCE AND TROUBLESHOOTING The spark gaps inside the High Frequency Arc Stabilizer have been pre-set at the factory. During operation, this spark gap setting will gradually increase due to erosion of the spark gap contacts. The spark gap should be checked and readjusted after every 200 hours of operation. Variations in spark gap distance can lead to excessive high frequency radiation being emitted. WARNING: High voltage is present inside the unit when plugged in. Unplug unit before servicing! To adjust the spark gap:

3. The spark gap should be set at .007-.008". Use a .007 feeler gauge and insert between the contacts. 4. Push the end contacts (one at a time) toward the center fixed contact until the gaps between the contacts are the against the feeler gauge. 5. Tighten the set screws securely and recheck the gap, making sure that the .007" feeler will slide through, but a .009" gauge will not. 6. Clean dust, dirt, grease, etc. from your unit. Airblow any dust and dirt that may have accumulated inside.

1. Remove the cover of the cabinet. 2. Loosen the set screws that hold the two outside contacts.

7. Reinstall the cover.
