SAFETY INSTRUCTIONS AND WARNINGS

WARNING

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.

9. Do not wrap cables around your body.

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 conﬁned 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 ﬂoor 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 ﬁtted with a proper shade of ﬁlter (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 ﬂash and glare; warn others not to watch the arc.

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

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

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

Manual 0-5116 1-1 Safety Instruction

ARC MASTER 175 TE SAFETY INSTRUCTIONS

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 breathe 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 conﬁned 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 vapours to form highly toxic and irritating gases.

WARNING

WELDING can cause ﬁre or explosion.

Sparks and spatter ﬂy off from the welding arc. The ﬂying sparks and hot metal, weld spatter, hot workpiece, and hot equipment can cause ﬁres and burns. Accidental contact of electrode or welding wire to metal objects can cause sparks, overheating, or ﬁre.

1. Protect yourself and others from flying sparks and hot metal.

2. Do not weld where flying sparks can strike flammable material.

3. Remove all ﬂammables within 35’ (10.7m) 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 ﬁre, and keep a ﬁre extinguisher nearby.

6. Be aware that welding on a ceiling, ﬂoor, bulkhead, or partition can cause ﬁre on the hidden side.

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

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.

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, Ofﬁce of Technology Assessment, Biological Effects of Power Frequency Electric & Magnetic Fields - Background Paper, OTA-BP-E-63 (Washington, DC: U.S. Government Printing Ofﬁce, May 1989): “...there is now a very large volume of scientiﬁc ﬁndings based on experiments at the cellular level and from studies with animals and people which clearly establish that low frequency magnetic ﬁelds and interact with, and produce changes in, biological systems. While most of this work is of very high quality, the results are complex. Current scientiﬁc 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 deﬁnite conclusions about questions of possible risk or to offer clear science-based advice on strategies to minimize or avoid potential risks.”

AVERTISSEMENT

L’ELECTROCUTION PEUT ETRE MORTELLE.

Une décharge électrique peut tuer ou brûler gravement. L’électrode et le circuit de soudage sont sous tension dès la mise en circuit. Le circuit d’alimentation et les circuits internes de l’équipement sont aussi sous tension dès la mise en marche. En soudage automatique ou semiautomatique avec ﬁl, ce dernier, le rouleau ou la bobine de ﬁl, le logement des galets d’entrainement et toutes les pièces métalliques en contact avec le ﬁl de soudage sont sous tension. Un équipement inadéquatement installé ou inadéquatement mis à la terre est dangereux.

1. Ne touchez pas à des pièces sous tension.

2. Portez des gants et des vêtements isolants, secs et non

troués.

3 Isolez-vous de la pièce à souder et de la mise à la terre au

moyen de tapis isolants ou autres.

MISE EN GARDE

7. N’utilisez que des porte-électrodes bien isolés. Ne jamais plonger les porte-électrodes dans l’eau pour les refroidir. Ne jamais les laisser traîner par terre ou sur les pièces à souder. Ne touchez pas aux porte-électrodes raccordés à deux sources de courant en même temps. Ne jamais toucher quelqu’un d’autre avec l’électrode ou le porte-électrode.

8. N’utilisez pas de câbles électriques usés, endommagés, mal épissés ou de section trop petite.

9. N’enroulez pas de câbles électriques autour de votre corps.

10. N’utilisez qu’une bonne prise de masse pour la mise à la terre de la pièce à souder.

11. Ne touchez pas à l’électrode lorsqu’en contact avec le circuit de soudage (terre).

12. N’utilisez que des équipements en bon état. Réparez ou remplacez aussitôt les pièces endommagées.

13. Dans des espaces conﬁnés ou mouillés, n’utilisez pas de source de courant alternatif, à moins qu’il soit muni d’un réducteur de tension. Utilisez plutôt une source de courant continu.

14. Portez un harnais de sécurité si vous travaillez en hauteur.

15. Fermez solidement tous les panneaux et les capots.

4. Déconnectez la prise d’alimentation de l’équipement ou arrêtez le moteur avant de l’installer ou d’en faire l’entretien. Bloquez le commutateur en circuit ouvert ou enlevez les fusibles de l’alimentation aﬁn d’éviter une mise en marche accidentelle.

Safety Instruction 1-6 Manual 0-5116

LE RAYONNEMENT DE L’ARC PEUT BRÛLER LES YEUX ET LA PEAU; LE BRUIT PEUT ENDOMMAGER L’OUIE.

L’arc de soudage produit une chaleur et des rayons ultraviolets intenses, susceptibles de brûler les yeux et la peau. Le bruit causé par certains procédés peut endommager l’ouïe.

AVERTISSEMENT

SAFETY INSTRUCTION ARC MASTER 175TE

1. Portez une casque de soudeur avec ﬁltre oculaire de nuance appropriée (consultez la norme ANSI Z49 indiquée ci-après) pour vous protéger le visage et les yeux lorsque vous soudez ou que vous observez l’exécution d’une soudure.

2. Portez des lunettes de sécurité approuvées. Des écrans latéraux sont recommandés.

3. Entourez l’aire de soudage de rideaux ou de cloisons pour protéger les autres des coups d’arc ou de l’éblouissement; avertissez les observateurs de ne pas regarder l’arc.

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

LES VAPEURS ET LES FUMEES SONT DANGEREUSES POUR LA SANTE.

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

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 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 ﬁches signalétiques et les consignes du fabricant relatives aux métaux, aux produits consummables, aux revêtements et aux produits nettoyants.

5. Ne travaillez dans un espace conﬁné 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.

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

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 des brûlures.

INSTALLATION

3.01 Environment

These units are designed for use in environments with increased hazard of electric shock. Examples of environments with increased hazard of electric shock 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 increased hazard of electric shock do not include places where electrically conductive parts in the near vicinity of the operator, which can cause increased hazard, have been insulated.

3.02 Location

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

3.03 Electrical Input Connections

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.

3.04 High Frequency Introduction

The importance of correct installation of high frequency welding equipment cannot be overemphasized. 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.

WARNING:

EXPLOSIVE 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 firing.

WARNING:

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

3.05 High Frequency Interference

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

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

3.06 Electromagnetic Compatibility

WARNING

Extra precautions for Electromagnetic Compatibility may be required when this Welding Power Source is used in a domestic situation.

A. Installation and Use - Users Responsibility

The user is responsible for installing and using the welding equipment according to the manufacturer’s instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases this remedial action may be as simple as earthing the welding circuit, see NOTE below. In other cases it could involve constructing an electromagnetic screen enclosing the Welding Power Source and the work, complete with associated input ﬁlters. In all cases, electromagnetic disturbances shall be reduced to the point where they are no longer trouble-some.

NOTE

1. 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.

2. Transmission via the Supply Lead: Without adequate shielding and ﬁltering, 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 ﬁltering is provided in the Power Source.

3. 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.

For 230 VAC operation, have a qualiﬁed person install according to applicable codes, and instructions.

NOTE

The welding circuit may or may not be earthed for safety reasons. Changing the earthing arrangements should only be authorized by a person who is competent to assess whether the changes will increase the risk of injury, e.g. by allowing parallel welding current return paths which may damage the earth circuits of other equipment. Further guidance is given in IEC 974-13 Arc Welding Equipment Installation and use (under preparation).

B. Assessment of Area

Before installing welding equipment, the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account.

Manual 0-5116 3-3 Installation

ARCMASTER 175 TE INSTALLATION

3.07 Setup for Welding

NOTE

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 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 ﬁne tune the welding current to suit the application.

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.

CAUTION

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

4.01 General Safety Precautions

Read and understand the safety instructions at the beginning of this manual prior to operating this machine.

Be sure to put on proper protective clothing and eye safeguards (welding coat, apron, gloves, and welding helmet, with proper lenses installed). See Safety Instructions and Warnings chapter included in this manual. Neglect of these precautions may result in personal injury.

Make all connections to the power source including electrode and work cables, as well as remote control cables, with the power source turned off. These connections could be electrically live with the power switch ON.

WARNING:

4.02 Overview

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 the electrode. 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 electrode, 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 ﬁne tune the welding current to suit the speciﬁc application. Refer to the electrode manufacture's literature for further information.

B. Over Heat Indicator

The welding power source is protected by a self resetting thermostat. The indicator will illuminate if the duty cycle of the power source has been exceeded. If the Over Heat light illuminates wait for the Over Heat light to extinguish before resuming welding.

C. Trigger Mode Selection Switch (TIG Mode only) Normal Mode

Press the TIG Torch Trigger Switch and hold depressed to weld. Release the TIG Torch Trigger Switch to stop welding. Downslope operates in TIG mode only. Whilst welding if the TIG Torch Trigger Switch is released, the welding current ramps down to zero current over a deﬁned period of time. The time period is determined by the Downslope Control Knob (F).

Latch Mode

This mode of welding is mainly used for long weld runs. The operator need only to press the TIG Torch Trigger Switch to activate and then release the TIG Torch Trigger Switch to continue to weld, then press the TIG Torch Trigger Switch again and release the TIG Torch Trigger Switch to stop welding. This eliminates the need for the operator to depress the TIG Torch Trigger Switch for the complete length of the weld. Downslope operates in TIG Mode only. To activate the Downslope function in Latch mode whilst welding, the TIG Torch Trigger Switch must be depressed and held which will ramp the Welding Current down to zero over a deﬁned period of time. The time period is determined by the Downslope Control Knob (F). At any time whilst welding if the TIG Torch Trigger Switch is depressed and released the arc will extinguish immediately.

Arc Force is effective when in Manual Arc Mode only. Arc Force control provides an adjustable amount of

Arc Force (or “dig”) control. This feature can be particularly beneﬁcial in providing the operator the ability to compensate for variability in joint ﬁt-up in certain situations with particular electrodes. In general increasing the Arc Force control toward ‘10’ (maximum Arc Force) allows greater penetration control to be achieved. Down Slope operates in TIG mode only. It is used to set the time for weld current to ramp down. Refer to Item C (Trigger Mode Selection Switch) for further information regarding Downslope operation.

G. Gas Outlet

The Gas Outlet is a 5/8-18 UNF female gas ﬁtting and is utilised for the connection of a suitable TIG Torch.

H. Post Gas Flow

Post Gas Flow is the time Gas ﬂows after the arc has extinguished. This is used to cool and reduce oxidisation of the Tungsten Electrode. Post Gas Flow time is proportional to the Welding Current. For example if the Welding Current is set to 10 amps the Post Gas Flow time will be approximately 3 +0/-1 seconds. For a Welding Current set to 175 Amps the Post Gas Flow time will be approximately 6 +1/-0 seconds. The Post Gas Flow time cannot be adjusted independently of the Welding Current.

I. Torch Trigger Socket

The 8 pin Torch Trigger Socket is used to connect the TIG Torch Trigger Switch to the welding Power Source. To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.

D. Process Selection Switch

Switches between Manual Arc, Lift TIG and HF TIG modes. Refer to Section 3.08 Setup for Manual Arc Welding and 3.09 Setup for TIG Welding.

E. Welding Current Control

The welding current is increased by turning the Weld Current Control Knob clockwise or decreased by turning the Weld Current Control Knob anticlockwise. The welding current should be set according to the speciﬁc application. Refer to application notes in this section for further information.

4.04 SMAW Electrode Polarity

Stick electrodes are generally connected to the "+" Positive Output Terminal and the work lead to the "−" Negative Output Terminal but if in doubt consult the electrode manufacturer's literature for further information.

4.05 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 pre-heating of heavy sections necessary to give proper fusion of weld and base metal.

Types of Electrodes

Arc Welding electrodes are classiﬁed 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

The electrodes dealt with in this publication can be used in most positions, i.e. they are suitable for welding in flat, horizontal, vertical and overhead positions. Numerous applications call for welds to be made in positions intermediate between these. Some of the common types of welds are shown in Figures 4-2 through 4-9.

4.14 Joint Preparations

In many cases, it will be possible to weld steel sections without any special preparation. For heavier sections and for repair work on castings, etc., it will be necessary to cut or grind an angle between the pieces being joined to ensure proper penetration of the weld metal and to produce sound joints.

In general, surfaces being welded should be clean and free of rust, scale, dirt, grease, etc. Slag should be removed from oxy-cut surfaces. Typical joint designs are shown in Figure 4-10.

4.15 Arc Welding Technique

A Word to Beginners

For those who have not yet done any welding, the simplest way to commence is to run beads on a piece of scrap plate. Use mild steel plate about 1/4" (6.0mm) thick and a 1/8" (3.2mm) electrode. Clean any paint, loose scale or grease off the plate and set it ﬁrmly on the work bench so that welding can be carried out in the down hand position. Make sure that the work clamp is making good electrical contact with the work, either directly or through the work table. For light gauge material, always clamp the work lead directly to the job, otherwise a poor circuit will probably result.

Operation 4-8 Manual 0-5116

OPERATION ARC MASTER 175 TE

20°

4.16 The Welder

Place yourself in a comfortable position before beginning to weld. Get a seat of suitable height and do as much work as possible sitting down. Do not hold your body tense. A taut attitude of mind and a tensed body will soon make you feel tired. Relax and you will ﬁnd that the job becomes much easier. You can add much to your peace of mind by wearing a leather apron and gauntlets. You won’t be worrying then about being burnt or sparks setting alight to your clothes.

Place the work so that the direction of welding is across, rather than to or from, your body. The electrode holder lead should be clear of any obstruction so that you can move your arm freely along as the electrode burns down. If the lead is slung over your shoulder, it allows greater freedom of movement and takes a lot of weight off your hand. Be sure the insulation on your cable and electrode holder is not faulty, otherwise you are risking an electric shock.

4.17 Striking the Arc

Practice this on a piece of scrap plate before going on to more exacting work. You may at ﬁrst experience difﬁculty due to the tip of the electrode “sticking” to the work piece. This is caused by making too heavy a contact with the work and failing to withdraw the electrode quickly enough. A low amperage will accentuate it. This freezing-on of the tip may be overcome by scratching the electrode along the plate surface in the same way as a match is struck. As soon as the arc is established, maintain a 1/16" (1.6mm) to 1/8" (3.2mm) gap between the burning electrode end and the parent metal. Draw the electrode slowly along as it melts down.

Another difﬁculty you may meet is the tendency, after the arc is struck, to withdraw the electrode so far that the arc is broken again. A little practice will soon remedy both of these faults.

Art # A-07696_AB

1.6 mm (1/16”)

4.18 Arc Length

The securing of an arc length necessary to produce a neat weld soon becomes almost automatic. You will ﬁnd that A very long arc produces a crackling or spluttering noise and the weld metal comes across in large, irregular blobs. The weld bead is ﬂattened and spatter increases. A short arc is essential if a high quality weld is to be obtained although if it is too short there is the danger of it being blanketed by slag and the electrode tip being solidiﬁed in. If this should happen, give the electrode a quick twist back over the weld to detach it. Contact or “touch-weld” electrodes such as E7014 do not stick in this way, and make welding much easier.

4.19 Rate of Travel

After the arc is struck, your next concern is to maintain it, and this requires moving the electrode tip towards the molten pool at the same rate as it is melting away. At the same time, the electrode has to move along the plate to form a bead. The electrode is directed at the

weldpoolatabout20°fromthevertical.Therateof

travel has to be adjusted so that a well-formed bead is produced.

If the travel is too fast, the bead will be narrow and strung out and may even be broken up into individual globules. If the travel is too slow, the weld metal piles up and the bead will be too large.

4.20 Making Welded Joints

Having attained some skill in the handling of an electrode, you will be ready to go on to make up welded joints.

A. Butt Welds

Set up two plates with their edges parallel, as shown in Figure 4-12, allowing 1/16" (1.6mm) to 3/32" (2.4mm) gap between them and tack weld at both ends. This is to prevent contraction stresses from the cooling weld metal pulling the plates out of alignment. Plates thicker than 1/4" (6.0mm) should have their mating

edgesbevelledtoforma70°to90°includedangle.

This allows full penetration of the weld metal to the root. Using a 1/8" (3.2mm) E7014 electrode at 120 amps, deposit a run of weld metal on the bottom of the joint.

Figure 4-11: Striking an arc

Manual 0- 5116 4-9 Operation

Do not weave the electrode, but maintain a steady rate of travel along the joint sufﬁcient to produce a well-formed bead. At ﬁrst you may notice a tendency for undercut to form, but keeping the arc length short,

theangleoftheelectrodeatabout20°fromvertical,

and the rate of travel not too fast, will help eliminate this. The electrode needs to be moved along fast

ARC MASTER 175 TE OPERATION

C. Vertical Welds

1. Vertical Up Tack weld a three feet length of angle iron

to your work bench in an upright position. Use a 1/8" (3.2mm) E7014 electrode and set the current at 120 amps. Make yourself comfortable on a seat in front of the job and strike the arc in the corner of the ﬁllet.

The electrodeneeds tobe about10° from

the horizontal to enable a good bead to be deposited. Refer Figure 4-16. Use a short arc, and do not attempt to weave on the ﬁrst run. When the ﬁrst run has been completed de-slag the weld deposit and begin the second run at the bottom. This time a slight weaving motion is necessary to cover the ﬁrst run and obtain good fusion at the edges. At the completion of each side motion, pause for a moment to allow weld metal to build up at the edges, otherwise undercut will form and too much metal will accumulate in the centre of the weld. Figure 4-17 illustrates multi-run technique and Figure 4-18 shows the effects of pausing at the edge of weave and of weaving too rapidly.

Art # A-07701

Figure 4-16: Single run vertical ﬁllet weld

Art # A-07702

Figure 4-18: Examples of vertical ﬁllet welds

2. Vertical Down The E7014 electrode makes welding in this

position particularly easy. Use a 1/8" (3.2mm) electrode at 120 amps. The tip of the electrode is held in light contact with the work and the speed of downward travel is regulated so that the tip of the electrode just keeps ahead of the slag. The electrode should point upwards at

anangleofabout45°.

3. Overhead Welds Apart from the rather awkward position

necessary, overhead welding is not much more difﬁcult that down hand welding. Set up a specimen for overhead welding by ﬁrst tacking a length of angle iron at right angles to another piece of angle iron or a length of waste pipe. Then tack this to the work bench or hold in a vice so that the specimen is positioned in the overhead position as shown in the sketch.

Theelectrodeisheldat45°tothehorizontal andtilted10°inthelineoftravel(Figure4-

19). The tip of the electrode may be touched lightly on the metal, which helps to give a steady run. A weave technique is not advisable for overhead ﬁllet welds. Use a 1/8" (3.2mm) E6012 electrode at 120 amps, and deposit the ﬁrst run by simply drawing the electrode along at a steady rate. You will notice that the weld deposit is rather convex, due to the effect of gravity before the metal freezes.

4.21 Distortion

Distortion in some degree is present in all forms of welding. In many cases it is so small that it is barely perceptible, but in other cases allowance has to be made before welding commences for the distortion that will subsequently occur. The study of distortion is so complex that only a brief outline can be attempted here.

4.22 The Cause of Distortion

Distortion is cause by:

A. Contraction of Weld Metal:

Molten steel shrinks approximately 11% in volume on cooling to room temperature. This means that a cube of molten metal would contract approximately 2.2% in each of its three dimensions. In a welded joint, the metal becomes attached to the side of the joint and cannot contract freely. Therefore, cooling causes the weld metal to ﬂow plastically, that is, the weld itself has to stretch if it is to overcome the effect of shrinking volume and still be attached to the edge of the joint. If the restraint is excessive, e.g. a heavy section of plate, then the weld metal may crack. Even in cases where the weld metal does not crack, there will still remain stresses “locked-up” in the structure. If the joint material is relatively weak, for example, a butt joint in 5/64" (2.0mm) sheet, the contracting weld metal may cause the sheet to become distorted.

B. Expansion and Contraction of Parent Metal in the Fusion Zone:

While welding is proceeding, a relatively small volume of the adjacent plate material is heated to a very high temperature and attempts to expand in all directions. It is able to do his freely at right angles to the surface of the plate (i.e., “through the weld”), but when it attempts to expand “across the weld” or “along the weld”, it meets considerable resistance, and to fulﬁl the desire for continued expansion, it has to deform plastically, that is, the metal adjacent to the weld is at a high temperature and hence rather soft, and, by expanding, pushes against the cooler, harder metal further away, and tends to bulge (or is “upset”). When the weld area begins to cool, the “upset” metal attempts to contract as much as it expanded, but, because it has been “upset”, it does not resume its former shape, and the contraction of the new shape exerts a strong pull on adjacent metal. Several things can then happen.

The metal in the weld area is stretched (plastic deformation), the job may be pulled out of shape by the powerful contraction stresses (distortion), or the weld may crack, in any case, there will remain “locked-up” stresses in the job. Figures 4-20 and 4- 21 illustrate how distortion is created.

4.23 Overcoming Distortion Effects

There are several methods of minimizing distortion effects.

A. Peening

This is done by hammering the weld while it is still hot. The weld metal is ﬂattened slightly and because of this the tensile stresses are reduced a little. The effect of peening is relatively shallow, and is not advisable on the last layer.

Manual 0- 5116 4-11 Operation

ARC MASTER 175 TE OPERATION

B. Distribution of Stresses

Distortion may be reduced by selecting a welding sequence which will distribute the stresses suitably so that they tend to cancel each other out. See Figures 4-25 through 4-28 for various weld sequences. Choice of a suitable weld sequence is probably the most effective method of overcoming distortion, although an unsuitable sequence may exaggerate it. Simultaneous welding of both sides of a joint by two welders is often successful in eliminating distortion.

C. Restraint of Parts

Art # A-07709

Forcible restraint of the components being welded is often used to prevent distortion. Jigs, positions, and tack welds are methods employed with this in view.

D. Presetting

It is possible in some cases to tell from past experience or to ﬁnd by trial and error (or less frequently, to calculate) how much distortion will take place in a given welded structure. By correct pre-setting of the components to be welded, constructional stresses can be made to pull the parts into correct alignment. A simple example is shown in Figure 4-22.

E. Preheating

Suitable preheating of parts of the structure other than the area to be welded can be sometimes used to reduce distortion. Figure 4-23 shows a simple application. By removing the heating source from B and C as soon as welding is completed, the sections B and C will contract at a similar rate, thus reducing

distortion.
