1.0 SAFETY PRECAUTIONS
1.1 GENERAL INSTRUCTIONS
Make sure this manual is carefully read and understood by the
operator.
1.2 LOCATION
Welding processes of any kind can be dangerous not only to
the operator but to any person situated near the equipment if
safety and operating rules are not strictly observed.
These are the main precautionary measures to observe:
• Operators should protect their body by wearing closed,
non-flammable protective clothing, without pockets or turned up
trousers.
• The operators should wear a non-flammable welding
helmet designed so as to shield the neck and the face. It is
necessary to keep the protective lens always clean and to
replace it when broken or cracked. It is advisable to put a
transparent glass between the lens and the welding area.
Welding should be done in a close area that does not open into
other working areas.
• The operators should never look at the welding arc without
the correct protection for the eyes. They should always wear
safety glasses with side shields to protect from flying particles.
• The welding process must be performed on metal coatings
thoroughly cleaned from layers of rust or paint to avoid production
of harmful fumes. The parts degreased with a solvent must be
dried before welding.
• Welding should never be done on metals or coated metals
containing zinc, mercury, chronium, graphite, lead cadmium or
beryllium unless the operator and the people standing in the same
area use an air-supplied respirator.

1.3 SAFETY INSTRUCTIONS
For your safety, before plugging in the welder, closely follow these
instructions:
• When working in a confined space, the welder must be
kept outside the welding area and the ground cable should be
fixed to the workplace. Never work in a damp or wet area, in
these conditions.
• Do not use damaged input or welding cables.
• The welding torch should never be pointed at the operator's
or another person's body.
• The welder must never be operated without its panels as
this could cause serious injury to the operator and could damage
the equipment.
1.4 FIRE PREVENTION
Make sure that appropriate fire prevention devices are available
near to the welding area;
All combustible material must be removed from the welding area.
1.6 ELECTRIC SHOCK
DANGER - ELECTRIC SHOCK CAN BE FATAL
Ifa person isfound unconscious and electric shock issuspected,
do not touch the person ifthey are in contact with any electrical
wires. Disconnect power from the machine and then use First
Aid. Dry wood, and other insulating material can be used to move
electrical cables, if necessary, away from the person.

2.0 ARC WELDING - HOW IT WORKS
Arc welding is a process by which two pieces of metal are joined
together using the heat developed by an electric arc between
the workpiece and an electrode (welding material).
The electrode is connected to one output side of the same
transformer. When the electrode comes into contact with the
workpiece an arc is struck. The high temperature of the arc melts
the electrode into the joint of the work piece and fusion occurs.

3.0 THERMAL OVERLOAD PROTECTION
If the duty cycle of the welder is exceeded, a thermostat will
automatically cut the power to prevent the machine from burning
out. If this should happen you will have to wait approximately 30
minutes until the transformer cools down. Then the thermostat
will automatically reset itself and you can continue welding: The
thermostat is a protective safety device and no harm will normally
be done to the transformer unless it is frequently over loaded, in
which case damage will eventually result. For the modes180E,
95E and EasiArc 150 the intervention of the thermostat is
indicated by the lighting of the ON/OFF switch.

4.0 ELECTRICAL CONNECTION
The wires in the input cable of this machine are colored in
accordance with the following code:
120V. 230V.
Green Ground Green & Yellow Ground
White Neutral Blue Live
Black Live Brown Live
120 Volts 20Amp grounded plug: Model 80E - 95E - 131E.
230 Volts grounded plug: Model 240TE
WARNING: This machine must be grounded.
Ifyou intend on using an extension cord make sure the wire cable
size is adequate in diameter.
Ifyou are in doubt about electrical connections consult a qualified
electrician. Do not attempt electrical repairs yourself.
5.0 PREPARATION FOR WELDING
1 With the On/Off switch (item B) in the Off position, connect
the welding leads as follows. (Does not apply to models 80E,
95E and Easi Arc 150 which have fixed leads):
• Connect the ground lead (item N) to the ground terminal
which is the black knob (item F) identified by the ground
symbol (see diagram 1), and secure the ground clamp (item
M) to the workpiece (item L). Note: For good contact the
ground clamp must be attached to the clean bare metal, not
painted.
• Connect the welding lead (item G) to the electrode terminal,
which is the black knob (item E) identified by the electrode
holder symbol (diagram 1) and secure an appropriate welding
rod (item I) by its bare end into the jaws of the elctrode holder
(item H). Note: All connections should be a good metal contact.
Clean with a wire brush where necessary.

6.0 WELDING TECHNIQUE
1 Plug your welder into the correct socket and switch on using
the ON/OFF switch (Item B). NOTE (for models 80E, 95E and Easi
Arc 150): If the machine stops at any time and the ON/OFF switch
lights, the thermostat has intervened. Wait for a few minutes while
the transformer cools down and when the ON/OFF switch goes out
again welding can begin.
2 Particularly for beginners, the most difficult aspect of the arc
welding process isthat of striking an arc. We strongly recommended
that you practice on pieces of scrap metal to get the feel of
the operation, before you start on an actual welding job.
3 Hold the electrode about 3/8" from the workpiece and at an
angle of about 70 degrees to 80 degrees to the work surface; take
care not to accidentally touch the workpiece until you are ready to
begin.
4 Holding the welding mask close to your face, give a short
stroke with the electrode on the workpiece. As soon as the arc is
struck, lightly withdraw the electrode from the workpiece to leave a
tiny gap of around 1/16". The current will flow across the gap with a
crackling noise and brilliant arc. Continue to weld in one direction,
maintaining the small gap as you go. At the end of the run, just
withdraw the electrode fully from the workpiece.
NOTE: When you strike an arc be sure to withdraw the electrode
fairly swiftly to leave the 1/16" gap, otherwise the electrode will weld
itself to the workpiece. Should this happen give the electrode a short
sharp jerk to free it and, if necessary strike the arc again.
5 Inspect the job carefully. With a correct combination of rod
size and amperage setting, the area of the weld should be a com-
plete fusion of the electrode metal being joined. Slag forming on
the surface should be chipped away with a hammer.
11

If the resulting weld looks irregular or messy, or shows signs of
porosity or slag contamination, you have almost certainly failed
to achieve the correct combination. Do not worry as practice
will soon cure this, and the following tips on welding pitfalls should
help to improve your technique quite quickly.
WARNING: Never look at welding arc, it can seriously
damage your eyes. Always use the face shield provided
or any proper welding mask.
HEALTH WARNING: When welding always make sure
there is adequate ventilation in the working area as the
welding process gives off toxic fumes.
7.0 WELDING PITFALLS
The arc welding technique is an acquired skill and will almost
certainly require considerable practice before perfect results are
obtained. The diagrams below should help to explain pitfalls in
your technique and how to overcome them.
1 Arc distance too short - this causes irregular masses of
weld to be deposited with slag contamination on the uneven
surface.
2 Arc distance too long - this causes poor penetration
resulting in a weak weld with excessive spatter and porosity.
Surface of weld is rough and the arc makes a hissing sound.
12

3 Electrode moved over workpiece too slowly - this causes
a very wide and heavy deposit which overlaps at the sides. It is
wasteful in terms of both time and electrodes used.
4 Electrode moved over the workpiece too quickly - this
causes poor penetration with a "stringy" and incomplete weld
deposit. Slag is very difficult to remove.
5 Amperage too low - this causes poor penetration and
causes the electrode to stick to the workpiece easily. Also results
in a very irregular and high weld deposit with difficult slag removal.
6 Amperage too high - this causes excessive penetration
with spatter and a deep and pointed crater. It may even cause
holes to be burnt in the workpiece. Burns electrodes very quickly.
/f_" \
13

7 The perfect weld -with the correct combination of arc length,
amperage regulation and inclination of the electrode you will, with
practice, produce the perfect weld. This should be regular with
uniform ripples and no slag contamination. The arc will make a
steady crackling sound.
8.0 MAINTENANCE AND SERVICING
Your CLARKE arc welder is a simple and robust unit, requiring
virtually no maintenance other than the guidelines shown below:
Keep the ventilation holes in welder clean to avoid the build up
of dirt and oxides inside the machine, this can reduce machine
output.
Check all cables periodically; they must be in a good condition
and free of cracks or cuts.
Always try to avoid getting particles of metal inside the machine
since they could cause short circuits.
Periodically clean the inside of the welder with compressed air
IMPORTANT: unplug the welder before cleaning.
