seam, and when not in use, is
insulated for safety. - Keep all
equipment well maintained.
• The operator shall prevent gas
cylinders in the vicinity of the
workpiece from becoming part of
the welding circuit.
FUMES & GASES
• The welding process generates
hazardous fumes as a by-product.
Inhalation of these fumes is
hazardous to health.
• Keep your head away from the
weld to avoid breathing the fumes.
• If welding in confined spaces,
ensure adequate ventilation and
use a fume extractor.
• By-products of welding can react
to create a toxic/explosive
environment.
FIRE OR EXPLOSION
Welding can cause fire and
explosions. Precautions should be
taken to prevent these hazards.
• Before starting work ensure the
area is clear of flammable
materials.
• Move any combustible materials to
a safe distance, especially
substances likely to generate a
dangerous vapour.

• Avoid carrying any fuels with you
e.g. cigarette lighters or matches.
PERSONAL PROTECTION
• The body should be protected by
suitable clothing.
• The use of neck protection may be
necessary against reflected
radiation.
• Arc welding machines generate a
magnetic field which is detrimental
to pacemakers. Consult your
doctor before going near active
welding equipment/operations.
• The UV and IR radiation generated
by welding is highly damaging to
the eyes, causing burns. This can
also affect the skin.
• Always use a suitable welding
shield equipped with appropriate
protective filters.
• Where there are pedestrians and
traffic, ensure a protective screen is
used to avoid accidental arc glare.
• Do not weld in the vicinity of

• Allow the weld time to cool. Hot
metal should never be handled
without gloves
• Take care when adjusting or
maintaining the torch, make sure it
has had time to cool sufficiently
and the welder is disconnected
from the mains supply.
• First aid facilities and a qualified first
aid person should be available
unless medical facilities are close
by, for immediate treatment of
flash burns of the eyes and for skin
burns.
• A hard hat should be worn when
others are working overhead.
• Flammable hair sprays/gels should
not be used by persons intending

1. Push the two halves of the shield
together as shown, making sure
the hooks and pins on the side
engage correctly.
2. Place the handle into position
and secure using the plastic nut
provided.
3. Working from the inside of the
shield, insert the clear glass panel
into the recess in the shield,
followed by the dark glass panel.
• The clear glass must be inserted
first.
4. Insert the two plastic screws to
clamp the glass panels from the
inside of the mask.
When replacing the glass panels,
only use parts supplied by Clarke International. The dark panel is a certified,
specific optical class, and should not be exchanged for any other type.
The clear glass panel should be replaced when it becomes badly pitted.
PREPARATION FOR USE
FITTING THE WELDING ROD
1. Select the appropriate welding rod, and insert it into the welding rod
holder.
• It should be approximately the same thickness as the workpieces
being welded.
PREPARING THE WORKPIECE
The area being welded should be perfectly clean. Any coating, plating or
corrosion must be removed, otherwise a good weld will be impossible to
achieve.
If the machine stops at any time and
the amber light on the front panel
illuminates, the thermal cutout has
activated.
Wait until the transformer has cooled
sufficiently (the amber light goes out)
before restarting work.
ATTACHING THE EARTH CLAMP
Attach the earth clamp firmly to the workpiece as close as possible to the
point of weld.
IMPORTANT: Ensure that the earth clamp is attached to clean, solid metal.
necessary, thoroughly clean with a wire brush or similar to guarantee a
good connection.
SWITCHING ON
1. Select the welding current by
turning the handwheel and
observing the setting on the scale,
on top of the machine.
The chart below is an indicator of the
thickness of material/ welding rod
thickness and the corresponding
welding current. This is intended as a
guide only.

NOTE: With practice you will get a feel for the best current settings for
IMPORTANT: BEFORE you strike an arc, always bring the face shield up to
protect your eyes.
1. Line up the electrode exactly over the spot where you want to
strike.
2. Position your shield in front of your face and tap the electrode
down firmly. Once you tap down and contact is made, you must
instantly raise the electrode to the required arc gap.
•The arc gap should be roughly the same as the diameter of the
electrode.
• If you withdraw the electrode too far once the arc is struck, you will
lose the arc and have to try again.
NOTE: One thing that usually happens when you are striking an arc is that
the electrode sticks to the work. It should come unstuck with a
sharp tug. If it will not free easily, turn off the welder immediately
as it will quickly overheat, then give the join a tap fro m the chi ppin g
hammer. As you get more experienced, this will happen less.
3. Once the arc is struck, move the electrode along its intended path,
keeping the tip in the molten pool at all times.
• You must also get used to feeding down the electrode steadily
as it burns away.
• An even crackling noise should be heard, which is an indication of a
good weld.
4. Inspect the job carefully, the area of weld should be complete fusion of
the electrode and parent metal(s).
• Any slag which forms on the surface should be chipped away with
the hammer/brush supplied.
• If the resultant weld looks messy and irregular, this is an indication of
porosity or slag contamination, and you have almost certainly failed
to achieve the correct combination of speed and current. This is a
common problem, so do not worry as practice will quickly cure this.
• When using the welder outside, you may need to take measures to
erect a wind break to make sure the shielding gas is not blown
away, thereby leaving a poor quality weld.
The arc welding technique is an acquired skill and requires considerable
practice before perfect results are obtained. The diagrams below will help to
explain the pitfalls in your technique and how to overcome them.
ARC TOO SHORT
This causes irregular masses of weld to be deposited, with
slag contamination on an uneven surface.
ARC TOO LONG
This causes poor penetration resulting in a weak weld with
excessive spatter and porosity. Surface of the weld is rough
and the arc makes a hissing sound
ELECTRODE MOVED TOO SLOWLY
This causes a very wide and heavy deposit which overlaps
at the sides. It is wasteful both in terms of time and electrode
use.
ELECTRODE MOVED TOO QUICKLY
This causes poor penetration with a ‘stringy’ and incomplete
weld deposit. Slag is very hard to remove.
CURRENT TOO LOW
This causes poor penetration and causes the electrode to
stick to the workpiece too readily. Also results in a very
irregular and high weld deposit. Slag is very hard to remove.
CURRENT TOO HIGH
This causes excessive penetration with spatter and deep
pointed crater. It may also cause holes to be burned in the
workpiece.
Burns electrodes very quickly.
THE PERFECT WELD
With the correct combination of arc length, current
regulation, inclination and speed 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.
WARNING: ELECTRICITY CAN KILL - NEVER TOUCH LIVE ELECTRICAL
COMPONENTS.
WARNING: DISCONNECT THE POWER SUPPLY BEFORE ALL INSPECTIONS
AND MAINTENANCE OPERATIONS
WARNING: BEWARE HOT SURFACES.
WARNING: ALWAYS LET THE POWER SUPPLY COOL DOWN BEFORE
ACCESSING INTERNAL COMPONENTS.
Frequency of maintenance operations depends on the operating conditions,
how intensively the welder is used and how clean or dirty the welding site is
(aggressive atmospheres etc).
Always inspect the earth return and torch hose before use, to ensure they are
in perfect condition and that the earth clamp is clean and secured correctly
to the cable.
As a general rule, the power supply should be inspected at least annually.
Consult your CLARKE dealer for advice if necessary.
