2 SAFETY PRECAUTIONS

WARNING: These Safety Precautions are for your protection. They summarize precautionary

information from the references listed in Additional Safety Information section. Before performing any

installation or operating procedures, be sure to read and follow the safety precautions listed below as

well as all other manuals, material safety data sheets, labels, etc. Failure to observe Safety

Precautions can result in injury or death.

PROTECT YOURSELF AND OTHERS

Some welding, cutting and gouging precesses are noisy and require ear

protection. The arc, like the sun, emits ultraviolet (UV) and other radiation

and can injure skin and eyes. Hot metal can cause burns. Training in the

proper use of the processes and equipment is essential to prevent accidents.

Therefore:

1. Always wear safety glasses with side shields in any work area, even if welding helmets face

shields and goggles are also required.

US

- 5 -

US warninga

2. Use a face shield fitted with the correct filter and cover plates to protect your eyes, face, neck

and ears from sparks and rays of the arc when operating or observing operations. Warn

bystanders not to watch the arc and not to expose themselves to the rays of the electric-arc or

hot metal.

3. Wear flameproof gauntlet type gloves, heavy long-sleeve shirt, cuffless trousers, high-topped

shoes and a welding helmet or cap for protection, to protect against arc rays and hot sparks or

hot metal. A flameproof apron may also be desirable as protection against radiated heat and

sparks.

4. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves and collars

should be kept buttoned and open pockets eliminated from the front of clothing.

5. Protect other personnel from arc rays and hot sparks with a suitable nonflammable partition or

curtains.

6. Use goggles over safety glasses when chipping slag or grinding. Chipped slag may be hot and

can fly far. Bystanders should also wear goggles over safety glasses.

FIRES AND EXPLOSIONS

Heat from flames and arcs can start fires. Hot slag or sparks can also cause

fires and explosions. Therefore:

1. Remove all combustible materials well away from the work area or cover the materials with a

protective nonflammable covering. Combusible materials include wood, clot, sawdust, liquid and

gas fuels, solvents, pants and coatings papper, etc.

2. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings and cause a

hidden smoldering fire or fires on the floor below. Make certain that such openings are protected

from hot sparks and metal.

3. Do not weld, cut or perform other hot work until the workpiece has been completely cleaned so

that there are no substances on the workpiece which might produce flammable or toxic vapors.

Do not do hot work on closed containers. They may explode.

4. Have fire extinguishing equipment handy for instant use, such as a garden hose, water pail, sand

bucket, or portable fire extinguisher. Be sure you are trained in its use.

5. Do not use equipment beyond its ratings. For example, overloaded welding cable can overheat

and create a fire hazard.

6. After completing operations, inspect the work area to make certain there are no hot sparks or hot

metal which could cause a later fire. Use fire watchers when necessary.

7. For additional information refer to NFPA Standard 51B, “Fire Prevention in Use of Cutting and

Welding Processes”, available from the National Fire Protection Association, Batterymarch Park,

Quincy, MA 02269.

ELECTRICAL SHOCK

Contact with live electrical parts and ground can cause severe injury or

death. DO NOT use AC welding current in damp areas, if movement is

confined, or if there is danger of falling. Therefore:

1. Be sure the power source frame (chassis) is connected to the ground system of the input power.

2. Connect the workpiece to a good electrical ground.

3. Connect the work cable to the workpiece. A poor or missing connection can expose you or others

to a fatal shock.

4. Use well-maintained equipment. Replace worn or damaged cables.

5. Keep everything dry, including clothing, work area, cables, torch/electrode holder and power

source.

6. Make sure that all parts of your bady are insulated from work and from ground.

7. Do not stand directly on metal or the earth while working in tight quarters or a damp area; stand

on dry boards or an insulating platform and wear rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the power.

9. Turn off the power before removing your gloves.

10. Refer to ANSI/ASC Standard Z49.1 (listed on next page) for specific grounding

recommendations. Do not mistake the work lead for a ground cable.

US

US warninga

ELECTRIC AND MAGNETIC FIELDS

May be dangerous. Electric current flowing through any conductor causes

localized Electric and Magnetic Fields (EMF). Welding and cutting current

creates EMF around welding cables and welding machines.

Therefore:

1. Welders having pacemakers should consult their physician before welding. EMF may interfere

with some pacemakers.

2. Exposure to EMF may have other health effects which are unknown.

3. Welders should use the following procedures to minimize exposure to EMF:

a. Route the electrode and work cables together. Secure them with tape when possible.

b. Never coil the torch or work cable around your body.

c. Do not place your body between the torch and work cables. Route cables on the same side

of your body.

d. Connect the work cable to the workpiece as close as possible to the area being welded.

e. Keep welding power source and cables as far away from your body as possible.

FUMES AND GASES

Fumes and gases, can cause discomfort or harm, particularly in confined

spaces. Do not breathe fumes and gases. Shielding gases can cause

asphyxiation.

Therfore:

1. Always provide adequate ventilation in the work area by natural or mechanical means. Do not

weld, cut or gouge on materials such as galvanized steel, stainless steel, cooper, zinc, lead

beryllium or cadmium unless positive mechanical ventilation is provided. Do not breathe fumes

from these materials.

2. Do not operate near degreasing and spraying operations. The heat or arc can react with

chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas and other irritant gases.

3. If you develop momentary eye, nose or throat irritation while operating, this is an indication that

ventilation is not adequate. Stop work and take necessary steps to improve ventilation in the work

area. Do not continue to operate if physical discomfort persists.

4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for specific ventilation recommendations.

5. WARNING: This product when used for welding or cutting, produces fumes or gases which

contain chemicals known to the State of Californa to cause birth defects and in some cases

cancer (California Health & Safety Code §25249.5 et seq.)

CYLINDER HANDLING

Cylinders, if mishandled, can rupture and violently release gas. Sudden

rupture of cylinder valve or relief device can injure or kill.

Therefore:

1. Use the proper gas for the process and use the proper pressure reducing regulator designed to

operate from the compressed gas cylinder. Do not use adaptors. Maintain hoses and fittings in

good condition. Follow manufacturer's operating instructions for mounting regulator to a

compressed gas cylinder.

2. Always secure cylinders in an upright position by chain or strap to suitable hand trucks,

undercarriages, benches, wall, post or racks. Never secure cylinders to work tables or fixtures

where they may become part of an electrical circuit.

3. When not in use, keep cylinder valves closed. Have valve protection cap in place if regulator is

not connected. Secure and move cylinders by using suitable hand trucks.

4. Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.

5. For additional information, refer to CGA Standard P-1, “Precations for Safe Handling of

Comporessed Gases in Cylinders”, which is available from Compressed Gas Association, 1235

Jefferson Davis Highway, Arlington, VA 22202.

6 INSTALLATION

The installation must be done by a professional.

Mains supply requirements

High power equipment may, due to the primary current drawn from the mains supply, influence the

power quality of the grid. Therefore connection restrictions or requirements regarding the

maximum permissible mains impedance or the required minimum supply capacity at the interface

point to the public grid may apply for some types of equipment (see technical data). In this case it

is the responsibility of the installer or user of the equipment to ensure, by consultation with the

distrubution network operator if necessary, that the equipment may be connected.

6.1 Lifting instruction

The power source is lifted by the handle or by the shoulder strap, supplied with the

power source. The strap is fastened as shown in the picture below.

of a maximum

length of 164 ft.

Supply from power generators

The power source can be supplied from different types of generators. However,

some generators may not provide sufficient power for welding. The generators with

AVR, equivalent or better type of regulation with rated power 5.5...6.5 kW are

recommended to supply the power source within it's full capacity.

It is also possible to use generators with lower rated power, starting from 3.0kW, but

in that case the setting must be proportionally limited. The power source is protected

against undervoltage. If the power supplied by the generator is not sufficient, the

welding is interrupted. Especially the welding start could be disturbed. In case of

disturbed welding process, either adjust the welding parameters or change to a more

powerful generator.

7.2 Operation

The power source is not powered instantly when the mains switch (1) is turned on.

After approximately 2 seconds the green lamp (2) indicates that the power source is

ready.

If the welding gun trigger is pressed while the power source is being turned on, the

operation is disabled, until the trigger is released. This is also indicated by the

orange lamp (3).

The main knob (6) is scaled in mm and ga. The numbers point out recommended

thicknesses of the mild steel workpiece to be welded with .030” wire. This knob

simultaneously adjusts both the wire feed speed and the average output voltage.

The knob (7) sets the arc length correction or i.e. the voltage correction.

The return cable (5) must be reliably connected to the workpiece or to the welding

table.

The side panel covering the wire feeder must be closed prior to welding.

The power source is instantly switched with the mains switch (1).

7.3 Polarity change

+/- TERMINALS

The power source is delivered with the welding wire connected to the plus pole.

Some wires, e.g. shelfshielded cored wires, are recommended to be welded with

negative polarity. Negative polarity means that the wire is connected to the minus

pole and the return cable to the plus pole. Check the recommended polarity for the

welding wire you want to use.

- 17 -

bc21a

The polarity can be changed as follows:

1. Switch off the power source and disconnect the mains cable.

2. Open the side panel.

3. Bend the rubber covers back to give access to the +/- terminals.

4. Remove the nuts and washers. Note the correct order of the washers.

5. Change the position of the cables to the desired polarity (see marking).

6. Install the washers in correct order and tighten the nuts to spanner tightness.

7. Make sure the rubber covers are covering the +/- terminals.

7.4 Wire feed pressure

Start by making sure that the wire moves smoothly through the wire guide. Then

set the pressure of the wire feeder's pressure rollers. It is important that the

pressure is not too great.

Fig 1 Fig 2

To check that the feed pressure is set correctly, you can feed out the wire against

an insolated object, e.g. a piece of wood.

When you hold the gun approx. 0.2” (5 mm) from the piece of wood (fig. 1) the

feed rollers should slip.

If you hold the gun approx. 2” (50 mm) from the piece of wood, the wire should be

7.5 Replacing and inserting wire

S Open the side panel.

S Place the spool on the hub and secure it with the lock.

S Disconnect the pressure arm by folding it sidewards, the pressure roller slides

away.

S Straighten out the new wire 3.9 - 7.9”. File away burrs and sharp edges from the

end of the wire before inserting it into the wire feeder.

S Make sure that the wire goes properly into the feed roller groove and into the

outlet nozzle and the wire liner.

S Secure the pressure arm.

S Close the side panel.

Feed the wire through the welding gun until it comes out through the nozzle. This

operation should be carried out carefully, as the wire is ready for welding and an

unintentional arc may occur. Keep the gun off conducting parts during feeding the

wire through and terminate wire feeding instantly when the wire comes out.

See Technical Data, chapter 5, for suitable wire dimensions for each wire type.

Use only 7.9” spools. Note! j 3.9"/2.2lbs spools are not applicable.

WARNING!

Do not keep the welding gun near the ears or the face during the wire feeding,

as this may result in personal injury.

7.5.1 Changing the feed roller groove

The power source is delivered with the feed roller set for .030/.040” welding wire. If

you want to use it for .024” wire you must change groove in the feed roller.

1. Fold back the pressure arm to release the pressure roller.

2. Switch on the power source and press the gun trigger to position the feed roller

so that the locking screw is visible.

3. Switch off the power source.

4. Use a 2mm Allen key to open the locking screw about half a turn.

5. Pull the feed roller off the shaft and turn it around. See marking on the side of the

feed roller for suitable wire diameters.

6. Put the roller back on the shaft and make sure it goes all the way in. You may

need to turn the roller to position the locking screw over the flat surface of the

shaft.

7. Tighten the locking screw.

7.6 Shielding gas

A mixture of carbon dioxide and argon or pure carbon dioxide can be used as

shielding gases.

7.7 Overheating protection

Overheating is indicated by lamp (3). A thermal overload fuse protects the unit against

overheating by disabling the welding if overheating occurs. The fuse resets automatic

ally when the unit has cooled.

8 MAINTENANCE

Regular maintenance is important for safe, reliable operation.

Supplier warranty is void if customer attempts any work on product during the

warranty period.

8.1 Inspection and cleaning

Power source

S Check regularly that the power source is free from dirt.

S How often and which cleaning methods apply depend on: the welding process,

arc times, placement, and the surrounding environment. It is normally sufficient

to blow the dust out of the power source with dry compressed air (reduced

pressure) once a year.

S Clogged or blocked air inlets and outlets otherwise result in overheating.

Welding gun

S Cleaning and replacement of the welding gun's wear parts should take place at

regular intervals in order to achieve trouble-free wire feed. Blow the wire guide

clean regularly and clean the contact tip.

8.2 Changing the wire liner

A. Loosen the fixing screw and take the roller off the axle.

B. Loosen the adaptor nut, straighten the gun cable and remove the liner.

C. Insert the replacement liner into the straightened cable until it touches the contact

tip.

D. Lock the liner with adaptor nut. Cut excess of liner so it sticks 0.3” out of the tip

adaptor.
