1. SAFETY INSTRUCTIONS

1.1. ELECTRICAL SAFETY

p WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:

You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other connectors for wear

or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices. A Residual Current Circuit Breaker (RCCB)

should be incorporated in the main distribution board. We also recommend that a Residual Current Device (RCD) is used. It is particularly important to use an RCD

with portable products that are plugged into a supply which is not protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual

Current Device by contacting your Sealey dealer.

You must also read and understand the following instructions concerning electrical safety.

1.1.1. The Electricity at Work Act 1989 requires that all portable electrical appliances, if used on business premises, are tested by a qualified electrician, using

a Portable Appliance Tester (PAT), at least once a year.

1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances and the safety of the

appliance operators. If in any doubt about electrical safety, contact a qualified electrician.

1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1. and 1.1.2. and use a

Portable Appliance Tester.

1.1.4. Ensure that cables are always protected against short circuit and overload.

1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure

that none is loose.

1.1.6. Important: Ensure that the voltage marked on the appliance matches the power supply to be used and

that the plug is fitted with the correct fuse - see fuse rating at right.

1.1.7. DO NOT pull or carry the appliance by the power cable.

1.1.8. DO NOT pull the plug from the socket by the cable.

1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty item repaired

or replaced by a qualified electrician. When a BS 1363/A UK 3 pin plug is damaged, cut the cable just

above the plug and dispose of the plug safely.

Fit a new plug according to the following instructions (UK only).

a) Connect the GREEN/YELLOW earth wire to the earth terminal E.

b) Connect the BROWN live wire to the live terminal L.

c) Connect the BLUE neutral wire to the neutral terminal N.

d) After wiring, check that there are no bare wires, that all wires have been correctly connected,

that the cable outer insulation extends beyond the cable restraint and that the restraint is tight.

Double insulated products, which are always marked with this symbol , are fitted with live (brown) and

neutral (blue) wires only. To rewire, connect the wires as indicated above - DO NOT connect either wire

to the earth terminal.

1.1.10. Products which require more than 13 amps are supplied without a plug. In this case you must contact a qualified electrician to ensure that a suitably rated

supply is available. We recommend that you discuss the installation of an industrial round pin plug and socket with your electrician.

1.1.11. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is preferred since any appliance plugged into it will be

protected. The cable core section is important and should be at least 1.5mm2, but to be absolutely sure that the capacity of the reel is suitable for this

product and for others which may be used in the other output sockets, we recommend the use of 2.5mm2section cable.

WARNING! Be very cautious if using a diesel generator. The generator must be stable with regard to frequency (H3), voltage and wave form.

The output must be higher than the power (kVA) of the inverter. The diesel generator must also be self regulating.

Use of a generator without a regulator may be dangerous and will invalidate your inverter warranty.

Note that model MW140PLUS has a supply filter to minimize the risk of damage from unstable power supplies and is, therefore, the preferred model when

the only source of power is a generator.

1.2. GENERAL SAFETY

DANGER! Unplug the inverter from the mains power supply before connecting or disconnect cables or performing maintenance or service.

Direct contact with the inverter circuit is dangerous.

3 Keep the inverter and cables in good working order and condition. Take immediate action to repair or replace damaged parts.

3 Use genuine parts and accessories only. Unapproved parts may be dangerous and will invalidate the warranty.

3 Keep the inverter clean for best and safest performance.

3 Locate the inverter in a suitable work area. Ensure that the area has adequate ventilation as welding fumes are harmful.

WARNING! Cable connectors must be turned fully into the quick plugs to ensure a good electrical contact. Loose connections will cause overheating,

rapid deterioration and loss in efficiency.

3 Ensure that there is no obstruction to the flow of clean, cool air around the machine and ensure that there are no conductive dusts, corrosive vapours or

humidity which could enter the inverter and cause serious damage.

3 Keep the work area clean and tidy and free from unrelated materials. Also ensure that the work area has adequate lighting.

WARNING: Use welding head shield to protect eyes and avoid exposing skin to ultraviolet rays given off by electric arc. Wear safety welding gauntlets.

3 Remove ill fitting clothing, remove ties, watches, rings and other loose jewellery and contain long hair.

3Ensure that the workpiece is correctly secured before operating the inverter.

3Avoid unintentional contact with workpiece. Accidental or uncontrolled switching on of the torch may be dangerous and will wear the nozzle.

3 Protect cables from heat and sharp or abrasive items.

3 Keep unauthorised persons away from the work area. Any persons working within the area must adorn the same protective items.

3 Operators must receive adequate training before using the inverter.

3 Stand correctly keeping a good footing and balance, ensure that the floor is not slippery and wear non-slip shoes.

WARNING: When unit is switched off the short-circuit light (fig 4. B) will come on for 10-15 seconds whilst the capacitor discharges. DO NOT open

the unit until the light goes out.

2.1. INTRODUCTION

These Inverters are lightweight, powerful and versatile. They are suitable for ARC or TIG welding using Scratch-Start method. All have Arc-Force circuitry making

them suitable for welding a wide variety of rods including rutile, basic and stainless of various sizes (see specifications). Machines also include thermal cut-out and

mains voltage LEDs and are fitted with Hot-Start systems to counter electrode sticking during scratch-starting. Model MW140PLUS has a supply filter to minimize

the risk of damage when powered from a generator. Model MW170 is also suitable for aluminium welding rods, and has thermostatic, over-voltage, under-voltage

and over-current protection circuitry.

2.2. DESCRIPTION

These models are constant current rectifiers for ARC welding and are controlled by a transistor bridge with a normal frequency of 32kHz. The specific characteristics

of the INVERTER system provide high speed and precise regulation, ensuring a high quality result for both stick electrode and TIG welding (DC).

The INVERTER system, regulated at the input of the primary mains, also allows for a drastic reduction in the volumes of both the transformer and the reactance.

This reduction in volume and weight enhances the mobility of the machines. The units have power modules which have been developed on a special printed circuit

designed to maximise reliability and reduce maintenance.

2.3. CIRCUIT SYSTEM DESCRIPTION Refer to fig. 1

1. Mains input (single phase), rectifier unit and condenser.

2. Transistors and drivers switching bridge (IGBT). Turns the mains rectified voltage into high frequency

alternating voltage (32khz) and permits power regulation according to the current/voltage of the weld.

3. High frequency transformer: The primary windings are fed by the voltage converted by Block 2 It has

the function of adapting voltage and current to the values required by the ARC welding procedure and,

simultaneously, isolates the welding circuit form the mains.

4. Secondary rectifier bridge with inductance. Changes the alternating current supplied by the secondary

windings into direct current.

5. Electronic and regulation board: Instantly checks the value of the welding current against that selected by the user. It modulates the commands of the

IGBT drivers, which control regulation. The control board also determines the dynamic response of the current transient during the phases of electrode fusion

(instant short circuit), and is responsible for the safety system.

3. ASSEMBLY

Unpack the product and check contents. Should there be any damaged or missing parts contact your supplier immediately.

WARNING! Ensure that the inverter is not plugged into the mains supply before assembling, connecting or disconnect cables.

Electrical installation, see Safety Instructions (Section 1).

WARNING! Failure to follow the electrical safety instructions will affect the operating performance and may damage the built-in safety system

which could result in personal injury or fatality and will invalidate the warranty.

3.1. ELECTRODE HOLDER CABLE CONNECTION

Before connect cables it is important to refer to the instructions on the electrode packaging which will indicate the correct polarity for the electrode, together

with the most suitable current to use.

3.1.1. ARC WELDING.

Normally, when ARC welding, the ELECTRODE HOLDER is connected to the POSITIVE (+) terminal (fig. 2).

3.1.2. TIG WELDING

Normally, when TIG welding alloys, the ELECTRODE HOLDER is connected to the NEGATIVE (-) terminal (fig. 2).

3.2. WORK CLAMP CABLE CONNECTION

The work clamp cable is connected to the inverter terminal which is not occupied by the electrode holder cable.

The clamp is connected to:

a) The workpiece.

b) A metal work bench. The connection must be as close to the proposed weld as possible.

WARNING! Cable connectors must be turned fully into the quick plugs to ensure a good electrical contact. Loose connections will cause overheating,

rapid deterioration and loss in efficiency. DO NOT use welding cables over 10m in length.

With the exception of a metallic workbench, DO NOT connect the work clamp to a metal structure which is not part of the workpiece, as this will

jeopardise weld quality and may be dangerous.

fig. 2

MW140.V2, MW140PLUS, MW150, MW170 - 1 - 110303

WARNING! Ensure that you read, understand and follow the safety instructions. Place the welding mask in front of your face before striking the arc.

5.1. ARC WELDING (Arc welding accessory kits available, contact you Sealey dealer)

5.1.1. Strike the electrode tip on the workpiece as if you were striking a match.

WARNING! DO NOT hit the electrode on the workpiece, as this may damage the electrode.

5.1.2. As soon as the arc is ignited, maintain a distance from the workpiece equal to the diameter of the electrode being used. Keep this distance as constant

as possible for the duration of the weld. As you advance along the workpiece the angle of the electrode must be maintained between 20Oto 30O.

5.1.3.At the end of the weld bead, bring the end of the electrode backward in order to fill the weld crater, quickly lift the electrode from the weld pool to

extinguish the arc.

5.2. TIG WELDING (TIG welding accessory kits available, contact you Sealey dealer).

TIG (Tungsten Inert Gas) welding uses an arc between a tungsten electrode and the work to fuse the joint. The electrode itself is not consumed and filler

metal may be required to build the weld profile.The process is protected from atmospheric contamination by a shield of inert gas. This gas is normally pure

argon, but helium by itself or a mixture of helium and argon may be used for special applications. For stainless steel use a mixture of argon and hydrogen.

5.2.1. Strike the electrode tip on the workpiece as if you were striking a match.

WARNING! DO NOT hit the electrode on the workpiece, as this may damage the electrode.

5.2.2. Point the electrode in the direction of the weld at about 2.5mm distance from the surface and use the arc to melt the metal at the joint.

5.2.3. To increase or decrease flow of gas, use the control knob on the torch handle.

5.2.4. Filler metal may be added by using cut lengths of wire over 1.5mm diameter (usually 1 metre in length). To use filler metal (for example when making a

fillet weld), add it to the leading edge of the weld pool.

4. CONTROLS & PREPARATION fig. 4

4.1. CONTROLS figs. 4 & 5

A. Potentiometer: To regulate welding current with scale graduated in Amps. May be regulated during welding.

B.Yellow LED: Normally off. When on it means no welding current due to one of the following faults:

1. Thermal protection: Inside machine the temperature is excessive. The machine is ON but will not

deliver current until a normal temperature is reached. Once this happens the re-start is automatic.

2. Mains over/under voltage protection: When mains voltage is too high (over 260V) or too low

(under 190V) the machine is blocked.

3. Short circuit protection: If there is a short-circuit lasting more than 1.5 seconds (i.e. electrode sticking), machine stops.

Re-start is automatic.

C. Models MW150 & MW170 Function Selection Switch: Enables the setting of the machine dynamics:

1. TIG: To gain maximum arc current stability.

2. HARD: To get maximum welding dynamics (hot start and arc force. Suitable for welding with hard electrodes (basic, aluminium etc).

3. SOFT: To weld with soft electrodes (rutile, inox etc.).

Models MW140.V2 & MW140PLUS: Green LED, mains power indicator, machine ready (fig. 5).

4.2. WELDING CURRENT

The welding current must be regulated according to the diameter of the electrode in use (see

chart on right) and the type of joint to be welded.

Further consideration must be given to the location of a weld, for example: Welds that are

performed on a horizontal surface require a higher voltage than those performed on a vertical

or overhead surface.

The mechanical character of the weld will be determined not only by the current intensity used, but also by the diameter and quality of the electrode, the

length of arc, the speed and position of the user. The condition of the electrode is an important factor and must never be wet or damp.

Should you have a problem with the welder, check the following:

l That the welding current is correct for the diameter and type of electrode being used.

l That when the main switch is on, the power lamp is ON. If this is not the case then there may be a mains supply problem.

l That the yellow LED is not illuminated. If it is this indicates either an over-voltage, an under-voltage or a short circuit.

l That the normal intermittence ratio is correct, and that the fan is working correctly.

l That you are using the correct voltage.

l That the cables are undamaged and that there is nothing causing a short-circuit.

l That all circuit connections are correct. In particular check that the work clamp is correctly attached to the workpiece. Ensure that there is no grease, paint etc on the contact surfaces.

7. TROUBLESHOOTING

6. MAINTENANCE

9. ELECTROMAGNETIC COMPATIBILITY

9.1. THIS EQUIPMENT IS IN CONFORMITY WITH THE EUROPEAN STANDARD ON THE ELECTROMAGNETIC COMPATIBILITY

OF ARC WELDING EQUIPMENT AND SIMILAR PROCESSES (e.g. ARC AND PLASMA CUTTING)

9.2. Protection against interference. (E.M.C.) The emission limits in this standard may not, however, provide full protection against

interference to radio and television reception when the equipment is used closer than 30m to the receiving antenna. In special cases,

when highly susceptible apparatus is being used in close proximity, additional mitigation measures may have to be employed in order

to reduce the electromagnetic emissions. At the same time there could occur some potential difficulties in having electromagnetic

compatibility in a non-industrial environment (e.g. in residential areas). Therefore it is most important that the equipment is used and

installed according to the following instructions.

9.3. Installation and use. The user is responsible for installing and using the equipment according to these instructions. If electromagnetic

disturbances are detected, then it shall be the responsibility of the user of the equipment to resolve the situation with the technical

assistance of the supplier. In some cases this remedial action may be as simple as earthing the circuit (see Note). 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 the electromagnetic disturbances shall be reduced to the point where they are no longer troublesome.

Note: The welding/cutting circuit may or may not be earthed for safety reasons. Changing the earthing arrangements should only be

authorised by a person who is competent to assess whether the changes will increase the risk of injury, e.g. by allowing parallel

welding/cutting circuit 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.

9.4. Assessment of area. Before installing the equipment the user shall make an assessment of potential electromechanical problems in the

surrounding area. The size of the surrounding area to be considered will depend on the structure of the building and other activities that

are taking place. The surrounding area may extend beyond the boundaries of the premises.

The following shall be taken into account :

a) Other supply cables, control cables, signalling and telephone cables, above, below and adjacent to the welding equipment.

b) Radio and television transmitters and receivers.

c) Computer and other control equipment.

d) Safety critical equipment, e.g. security monitoring of industrial equipment.

e) The health of people in the vicinity, e.g. persons fitted with a pacemaker or hearing aid.

f) Equipment used for calibration or measurement.

g) The immunity of other equipment in the environment. The user shall ensure that other equipment being used in the environment is

compatible. This may require additional protective measures.

h) The time of day that welding and other activities are to be carried out.

9.5. Mains supply. The equipment should be connected to the mains supply according to these instructions. If interference occurs, it may be

necessary to take additional precautions such as filtering of the mains supply. Consideration should also be given to shielding the supply

cable of permanently installed equipment in metallic conduit or equivalent. This shielding should be connected to the power source so

that good electrical contact is maintained between the conduit and the welding power source enclosure.

9.6. Maintenance of the equipment. The equipment should be routinely maintained according to these instructions. All access and service

covers should be closed and properly fastened when the welding equipment is in operation. The welding equipment should not be modified

in any way except for those changes and adjustments covered in these instructions. In particular, the spark gaps of any arc striking and

stabilising devices should be adjusted and maintained according to the instructions.

9.7. Cables. The welding/cutting cables should be kept as short as possible and should be positioned close together, running at or close

to the floor level.

9.8. Equipotential bonding. Bonding of all metallic components in the welding/cutting installation and adjacent to it should be considered.

However, metallic components bonded to the workpiece will increase the risk that the operator could receive a shock by touching these

metallic components and the electrode at the same time. The operator should be insulated from all such bonded metallic components.

9.9. Earthing of the workpiece. Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of its size

and position, e.g. ships hull or building steelwork, a connection bonding the workpiece to earth may reduce emissions in some, but not

all instances. Care should be taken to prevent the earthing of the workpiece increasing the risk of injury to others or damage to other

electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece,

but in some countries where direct connection is not permitted, the bonding should be achieved by a suitable capacitance, selected

according to national regulations.

9.10. Screening and shielding. Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems

of interference. Screening of the entire welding/cutting installation may be considered for special applications.
