SAFETY INSTRUCTIONS AND WARNINGS

PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR. DO NOT LOSE THESE INSTRUCTIONS. READ OPERATING/INSTRUCTION MANUAL BEFORE INSTALLING, OPERATING OR SERVICING THIS EQUIPMENT.

Welding products and welding processes can cause serious injury or death, or damage to other equipment or property, if the operator does not strictly observe all safety rules and take precautionary actions.

Safe practices have developed from past experience in the use of welding and cutting. These practices must be learned through study and training before using this equipment. Some of these practices apply to equipment connected to power lines; other practices apply to engine driven equipment. Anyone not having extensive training in welding and cutting practices should not attempt to weld.

Safe practices are outlined in the American National Standard Z49.1 entitled: SAFETY IN WELDING AND CUTTING. This publication and other guides to what you should learn before operating this equipment are listed at the end of these safety precautions. HAVE ALL INSTALLATION, OPERATION, MAINTENANCE,

AND REPAIR WORK PERFORMED ONLY BY QUALIFIED PEOPLE.

1.01 Arc Welding Hazards

WARNING

ELECTRIC SHOCK can kill.

Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input power circuit and machine internal circuits are also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard.

1. Do not touch live electrical parts.

2. Wear dry, hole-free insulating gloves and body protection.

3. Insulate yourself from work and ground using dry insulating mats or covers.

4. Disconnect input power or stop engine before installing or servicing this equipment. Lock input power disconnect switch open, or remove line fuses so power cannot be turned on accidentally.

5. Properly install and ground this equipment according to its Owner’s Manual and national, state, and local codes.

6. Turn off all equipment when not in use. Disconnect power to equipment if it will be left unattended or out of service.

7. Use fully insulated electrode holders. Never dip holder in water to cool it or lay it down on the ground or the work surface. Do not touch holders connected to two welding machines at the same time or touch other people with the holder or electrode.

8. Do not use worn, damaged, undersized, or poorly spliced cables.

9. Do not wrap cables around your body.

WARNING

10. Ground the workpiece to a good electrical (earth) ground.

11. Do not touch electrode while in contact with the work (ground) circuit.

12. Use only well-maintained equipment. Repair or replace damaged parts at once.

13. In conﬁ ned spaces or damp locations, do not use a welder with AC output unless it is equipped with a voltage reducer. Use equipment with DC output.

14. Wear a safety harness to prevent falling if working above ﬂ oor level.

15. Keep all panels and covers securely in place.

WARNING

ARC RAYS can burn eyes and skin; NOISE can damage hearing. Arc rays from the welding process produce intense heat and strong ultraviolet rays that can burn eyes and skin. Noise from some processes can damage hearing.

1. Wear a welding helmet ﬁ tted with a proper shade of ﬁ lter (see ANSI Z49.1 listed in Safety Standards) to protect your face and eyes when welding or watching.

2. Wear approved safety glasses. Side shields recommended.

3. Use protective screens or barriers to protect others from ﬂ ash and glare; warn others not to watch the arc.

4. Wear protective clothing made from durable, ﬂ ame-resistant material (wool and leather) and foot protection.

5. Use approved ear plugs or ear muffs if noise level is high.

WARNING

FUMES AND GASES can be hazardous to your health. Welding produces fumes and gases. Breathing these fumes

and gases can be hazardous to your health.

1. Keep your head out of the fumes. Do not breath the fumes.

2. If inside, ventilate the area and/or use exhaust at the arc to remove welding fumes and gases.

3. If ventilation is poor, use an approved air-supplied respirator.

4. Read the Material Safety Data Sheets (MSDSs) and the manufacturer’s instruction for metals, consumables, coatings, and cleaners.

5. Work in a conﬁ ned space only if it is well ventilated, or while wearing an air-supplied respirator. Shielding gases used for welding can displace air causing injury or death. Be sure the breathing air is safe.

6. Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form highly toxic and irritating gases.

7. Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the coating is removed from the weld area, the area is well ventilated, and if necessary, while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded.

1. Protect yourself and others from ﬂ ying sparks and hot metal.

2. Do not weld where ﬂ ying sparks can strike ﬂ ammable material.

3. Remove all ﬂ ammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them with approved covers.

4. Be alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

5. Watch for ﬁ re, and keep a ﬁ re extinguisher nearby.

6. Be aware that welding on a ceiling, ﬂ oor, bulkhead, or partition can cause ﬁ re on the hidden side.

7. Do not weld on closed containers such as tanks or drums.

8. Connect work cable to the work as close to the welding area as practical to prevent welding current from traveling long, possibly unknown paths and causing electric shock and ﬁ re hazards.

9. Do not use welder to thaw frozen pipes.

10. Remove stick electrode from holder or cut off welding wire at contact tip when not in use.

WARNING

FLYING SPARKS AND HOT METAL can cause injury. Chipping and grinding cause ﬂ ying metal. As welds cool,

they can throw off slag.

1. Wear approved face shield or safety goggles. Side shields recommended.

WARNING

WELDING can cause ﬁ re or explosion. Sparks and spatter ﬂ y off from the welding arc. The ﬂ ying

sparks and hot metal, weld spatter, hot workpiece, and hot equipment can cause ﬁ res and burns. Accidental contact of electrode or welding wire to metal objects can cause sparks, overheating, or ﬁ re.

1.02 Principal Safety Standards

! WARNING

This product, when used for welding or cutting, produces fumes or gases which contain chemicals know to the State of California to cause birth defects and, in some cases, cancer. (California Health & Safety code Sec. 25249.5 et seq.)

NOTE

Considerations About Welding And The Effects of Low Frequency Electric and Magnetic Fields

The following is a quotation from the General Conclusions Section of the U.S. Congress, Ofﬁ ce of Technology Assessment, Biological Effects of Power Frequency Electric & Magnetic Fields - Background Paper, OTA-BP-E-63 (Washington, DC: U.S. Government Printing Ofﬁ ce, May 1989): “...there is now a very large volume of scientiﬁ c ﬁ ndings based on experiments at the cellular level and from studies with animals and people which clearly establish that low frequency magnetic ﬁ elds and interact with, and produce changes in, biological systems. While most of this work is of very high quality, the results are complex. Current scientiﬁ c understanding does not yet allow us to interpret the evidence in a single coherent framework. Even more frustrating, it does not yet allow us to draw deﬁ nite conclusions about questions of possible risk or to offer clear science-based advice on strategies to minimize or avoid potential risks.”

To reduce magnetic fields in the workplace, use the following procedures.

1. Keep cables close together by twisting or taping them.

2. Arrange cables to one side and away from the operator.

3. Do not coil or drape cable around the body.

4. Keep welding power source and cables as far away from body as practical.

ARCMASTER® 160TS

4. Portez des vêtements en matériaux ignifuges et durables (laine et cuir) et des chaussures de sécurité.

5. Portez un casque antibruit ou des bouchons d’oreille approuvés lorsque le niveau de bruit est élevé.

AVERTISSEMENT

7. Ne soudez des tôles galvanisées ou plaquées au plomb ou au cadmium que si les zones à souder ont été grattées à fond, que si l’espace est bien ventilé; si nécessaire portez un respirateur à adduction d’air. Car ces revêtements et tout métal qui contient ces éléments peuvent dégager des fumées toxiques au moment du soudage.

AVERTISSEMENT

LES VAPEURS ET LES FUMEES SONT DANGEREUSES POUR LA SANTE.

Le soudage dégage des vapeurs et des fumées dangereuses à respirer.

LE SOUDAGE PEUT CAUSER UN INCENDIE OU UNE EXPLOSION

L’arc produit des étincellies et des projections. Les particules volantes, le métal chaud, les projections de soudure et l’équipement surchauffé peuvent causer un incendie et

1. Eloignez la tête des fumées pour éviter de les respirer.

2. A l’intérieur, assurez-vous que l’aire de soudage est bien ventilée ou

des brûlures. Le contact accidentel de l’électrode ou du ﬁ l-électrode avec un objet métallique peut provoquer des étincelles, un échauffement ou un incendie.

que les fumées et les vapeurs sont aspirées à l’arc.

3. Si la ventilation est inadequate, portez un respirateur à adduction d’air approuvé.

4. Lisez les ﬁ ches signalétiques et les consignes du fabricant relatives aux métaux, aux produits consummables, aux revêtements et aux produits nettoyants.

5. Ne travaillez dans un espace conﬁ né que s’il est bien ventilé; sinon, portez un respirateur à adduction d’air. Les gaz protecteurs de soudage peuvent déplacer l’oxygène de l’air et ainsi causer des malaises ou la mort. Assurez-vous que l’air est propre à la respiration.

6. Ne soudez pas à proximité d’opérations de dégraissage, de nettoyage ou de pulvérisation. La chaleur et les rayons de l’arc peuvent réagir avec des vapeurs et former des gaz hautement toxiques et irritants.

1. Protégez-vous, ainsi que les autres, contre les étincelles et du métal chaud.

2. Ne soudez pas dans un endroit où des particules volantes ou des projections peuvent atteindre des matériaux inﬂ ammables.

3. Enlevez toutes matières inﬂ ammables dans un rayon de 10, 7 mètres autour de l’arc, ou couvrez-les soigneusement avec des bâches approuvées.

4. Méﬁ ez-vous des projections brulantes de soudage susceptibles de pénétrer dans des aires adjacentes par de petites ouvertures ou ﬁ ssures.

2.07 Transporting Methods

These units are equipped with a handle for carrying purposes.

WARNING

ELECTRIC SHOCK can kill. DO NOT TOUCH live electrical parts. Disconnect input power conductors from de-energized supply line before moving the welding power source.

WARNING

FALLING EQUIPMENT can cause serious personal injury and equipment damage.

Lift unit with handle on top of case. Use handcart or similar device of adequate capacity. If using a fork lift vehicle, place and secure unit on a proper

skid before transporting.

• Location

Be sure to locate the welder according to the following guidelines:

• In areas free from moisture and dust.

• Ambient temperature between 0 degrees C to 40 degrees C.

• In areas free from oil, steam and corrosive gases.

• In areas not subjected to abnormal vibration or shock.

• In areas not exposed to direct sunlight or rain.

• Place at a distance of 12” (304.79mm) or more from walls or similar that could restrict natural airﬂ ow for cooling.

WARNING

Thermal Arc advises that this equipment be electrically connected by a qualiﬁ ed electrician.

• Electrical Input Connections

2.08 Installation Recommendations

• Environment

The ArcMaster 160TS is designed for use in adverse environments.

Examples of environments with increased adverse conditions are -

a. In locations in which freedom of movement is restricted,

so that the operator is forced to perform the work in a cramped (kneeling, sitting or lying) position with physical contact with conductive parts,

b. In locations which are fully or partially limited by

conductive elements, and in which there is a high risk of unavoidable or accidental contact by the operator,

c. In wet or damp hot locations where humidity or

perspiration considerably reduces the skin resistance of the human body and the insulation properties of accessories.

Environments with adverse conditions do not include places where electrically conductive parts are in the near vicinity of the operator, which can cause increased hazard, have been

insulated.

WARNING

ELECTRIC SHOCK can kill; SIGNIFICANT DC VOLTAGE is present after removal of input power.

DO NOT TOUCH live electrical parts. SHUT DOWN welding power source, disconnect input power

employing lockout/tagging procedures. Lockout/tagging procedures consist of padlocking line disconnect switch in open position, removing fuses from fuse box, or shutting off and red-tagging circuit breaker or other disconnecting device.

• Electrical Input Requirements

Operate the welding power source from a single-phase 50/60 Hz, AC power supply. The input voltage must match one of the electrical input voltages shown on the input data label on the unit nameplate. Contact the local electric utility for information about the type of electrical service available, how proper

connections should be made, and inspection required. The line disconnect switch provides a safe and convenient

means to completely remove all electrical power from the welding power supply whenever necessary to inspect or service the unit.

NOTE

ARCMASTER® 160TS

Refer to ﬁ gure 3 and:

TThis unit is equipped with a 115 VAC (NEMA 5-15) plug modeled on the two-conductor with earth power cable that is connected at the welding power source for single phase electrical input power. For 230 VAC operation, have a qualiﬁ ed person install according to applicable codes, and instructions.

Do not connect an input (WHITE or BLACK) conductor to the ground terminal.

Do not connect the ground (GREEN) conductor to an input line terminal.

NOTE

Fuse size is based on not more than 200 percent of the rated input amperage of the welding power source (Based on Article 630, National Electrical Code).

1. Connect end of ground (GREEN) conductor to a suitable ground. Use a grounding method that complies with all applicable electrical codes.

2. Connect ends of line 1 (BLACK) and line 2 (WHITE) input conductors to a de-energized line disconnect switch.

• Input Power

Each unit incorporates an INRUSH circuit and input voltage sensing circuit. When the MAIN CIRCUIT SWITCH is turned on, the inrush circuit provides a pre-charging of the input capacitors. SCR’s in the Power Control Assembly (PCA) will turn on after the

input capacitors have charged to full operating voltage (after approximately 5 seconds).

NOTE

Note the available input power. Damage to the PCA could occur if 460VAC or higher is applied.

The following 115/230V Primary Current recommendations are required to obtain the maximum welding current and duty cycle from this welding equipment:

Model

ArcMaster 160TS 12/3 AWG minimum

• High Frequency Introduction

The importance of correct installation of high frequency welding equipment cannot be over-emphasized. Interference due to high frequency initiated or stabilized arc is almost invariably traced to improper installation. The following information is intended as a guide for personnel installing high frequency welding machines.

Explosives

The high frequency section of this machine has an output similar to a radio transmitter. The machine should NOT be used in the vicinity of blasting operations due to the danger of premature ﬁ ring.

Computers

It is also possible that operation close to computer installations may cause computer malfunction.

• High Frequency Interference

Interference may be transmitted by a high frequency initiated or stabilized arc welding machine in the following ways:

Direct Radiation

Radiation from the machine can occur if the case is metal and is not properly grounded. It can occur through apertures such as open access panels. The shielding of the high frequency unit in the Power Source will prevent direct radiation if the equipment is properly grounded.

Transmission via the Supply Lead

Without adequate shielding and ﬁ ltering, high frequency energy may be fed to the wiring within the installation (mains) by direct coupling. The energy is then transmitted by both radiation and conduction. Adequate shielding and ﬁ ltering is provided in the Power Source.

Radiation from Welding Leads

Radiated interference from welding leads, although pronounced in the vicinity of the leads, diminishes rapidly with distance. Keeping leads as short as possible will minimize this type of interference. Looping and suspending of leads should be avoided where possible.

TIG STICK

160A @ 35%

Re-radiation from Unearthed Metallic Objects

A major factor contributing to interference is re-radiation from unearthed metallic objects close to the welding leads. Effective grounding of such objects will prevent re-radiation in most cases.

2.10 Duty Cycle

The duty cycle of a welding power source is the percentage of a ten (10) minute period that it can be operated at a given output without causing overheating and damage to the unit. If the welding amperes decrease, the duty cycle increases. If the welding amperes are increased beyond the rated output, the duty cycle will decrease.

WARNING

Exceeding the duty cycle ratings will cause the thermal overload protection circuit to become energized and shut down the output until the unit has cooled to normal operating temperature.

CAUTION

Continually exceeding the duty cycle ratings can cause damage to the welding power source and will void the manufacturer’s warranty.

NOTE

Due to variations that can occur in manufactured products, claimed performance, voltages, ratings, all capacities, measurements, dimensions and weights quoted are approximate only. Achievable capacities and ratings in use and operation will depend upon correct installation, use, applications, maintenance and service.

SECTION 4:

SET-UP FOR SMAW (STICK) AND GTAW (TIG)

Conventional operating procedures apply when using the Welding Power Source, i.e. connect work lead directly to work piece and electrode lead is used to hold electrode. Wide safety margins provided by the coil design ensure that the Welding Power Source will withstand short-term overload without adverse effects. The welding current range values should be used as a guide only. Current delivered to the arc is dependent on the welding arc voltage, and as welding arc voltage varies between different classes of electrodes, welding current at any one setting would vary according to the type of electrode in use. The operator should use the welding current range values as a guide, then ﬁ nally adjust the current setting to suit the application.

CAUTION

WARNING

Before connecting the work clamp to the work and inserting the electrode in the electrode holder make sure the Primary power supply is switched off.

Remove any packaging material prior to use. Do not block the air vents at the front or rear or sides of the Welding Power Source.

CAUTION

DO NOT change the Weld Mode or Weld Process Mode until after POST-FLOW time has ﬁ nished.

Pulse Controls

(Pulse Width) (Pulse Frequency)

(Peak Current)

(Base)

round Current

Back

The Pulse controls are used primarily to control heat input. Pulse offers a number of advantages as follows:

1) Control puddle – size and ﬂ uidity (especially out of position).

2) Increase penetration

3) Travel speed control

4) Better consistent quality

5) Distortion on lighter or thinner materials.

Pulse-current provides a system in which the welding current continuously changes between two levels. During the periods of Peak current heating and fusion takes place and during the background (base) current periods, cooling and solidiﬁ cation take place. Pulse Width is the time in one cycle the current stays at the peak current setting. Pulse Frequency measured in Hertz is the number of cycles per second the current travels between peak and background current settings. It is as if the foot rheostat were moved up and down to increase and decrease the welding current on a regular basis. The faster you moved the foot rheostat up and down the faster the frequency.

7.01 Electrode Polarity

Stick electrodes are generally connected to the ‘+’ terminal and the work lead to the ‘−’ terminal but if in doubt consult the electrode manufacturers literature.

7.02 Effects of Stick Welding Various Materials

High tensile and alloy steels

The two most prominent effects of welding these steels are the formation of a hardened zone in the weld area, and, if suitable precautions are not taken, the occurrence in this zone of under-bead cracks. Hardened zone and under-bead cracks in the weld area may be reduced by using the correct electrodes, preheating, using higher current settings, using larger electrodes sizes, short runs for larger electrode deposits or tempering in a furnace.

Manganese steels

The effect on manganese steel of slow cooling from high temperatures is to embrittle it. For this reason it is absolutely essential to keep manganese steel cool during welding by quenching after each weld or skip welding to distribute the heat.

Cast Iron

Most types of cast iron, except white iron, are weldable. White iron, because of its extreme brittleness, generally cracks when attempts are made to weld it. Trouble may also be experienced when welding white-heart malleable, due to the porosity caused by gas held in this type of iron.

Copper and alloys

The most important factor is the high rate of heat conductivity of copper, making preheating of heavy sections necessary to give proper fusion of weld and base metal.

Types of Electrodes

Arc Welding electrodes are classiﬁ ed into a number of groups depending on their applications. There are a great number of electrodes used for specialized industrial purposes which are not of particular interest for everyday general work. These include some low hydrogen types for high tensile steel, cellulose types for welding large diameter pipes, etc. The range of electrodes dealt with in this publication will cover the vast majority of applications likely to be encountered; are all easy to use and all will work on even the most basic of welding machines.
