insulated for safety. - Keep all
equipment well maintained.

• The operator shall prevent gas
cylinders in the vicinity of the work
piece 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.

3

• The welding arc can cause serious
burns. Avoid contact with skin.

• Sparks and molten metal are
ejected during welding. Take
precautions to prevent fires.

• Sparks and molten metal can pass
through gaps. Be aware that fire
can start out of sight.

• Do not weld pressurised containers.
or containers containing
flammable vapours e.g. fuel tanks.

• Always have appropriate fire
fighting equipment to hand
suitable for use in electrical
environments.

• 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 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
children or animals and ensure no­one is looking before striking an
arc.

• Wear hearing protection if
required.

• Allow the weld time to cool. Hot
metal should never be handled
without gloves.

• Take care when adjusting or
maintaining the torch, that 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 skin
burns.

• A hard hat should be worn when
others are working overhead.

• Flammable hair sprays/gels should
not be used by persons intending
to weld or cut.

PROTECTIVE CLOTHING

• Wear gauntlet gloves designed for
use in welding,

• Wear an apron, and protective

FEATURES

THERMAL CUTOUT

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.

USING THE WELDER

ATTACHING THE EARTH CLAMP

Attach the earth clamp firmly to the workpiece as close as possible to the
point of weld.

Ensure that the earth clamp is attached to clean, solid metal. If necessary
thoroughly clean with a wire brush or similar to guarantee a good connection.

SETTING THE WELDING CURRENT

1. Select the welding current by
turning the adjustment dial 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.

STRIKING AN ARC

IMPORTANT: BEFORE YOU STRIKE AN ARC, BRING THE FACE SHIELD UP TO
PROTECT YOUR EYES.

1. Switch ON the machine.

2. Line up the electrode exactly
over the spot where you want
to strike.

3. Position your shield in front of
your face and tap down firmly
with the electrode. 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, then turn off the welder
immediately as it will quickly overheat, then give the join a tap from
the chipping hammer. As you get more experienced, this will
happen less.

4. 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.

5. Inspect the job carefully, the area of weld should be a 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 working speed and current.
This is a common problem, so do not worry as practice will quickly
cure this.

WELDING PITFALLS

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
easily stick to the workpiece. 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.

MAINTENANCE

WARNING: ELECTRICITY CAN KILL - NEVER TOUCH LIVE ELECTRICAL
COMPONENTS.

WARNING: DISCONNECT THE POWER SUPPLY BEFORE ALL INSPECTION
AND MAINTENANCE OPERATION BEWARE HOT SURFACES.

WARNING: ALWAYS LET THE POWER SUPPLY COOL DOWN BEFORE
ACCESSING INTERNAL COMPONENTS.

The fequency 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.

DUTY CYCLE

This welder is covered by regulations
EN60974-1 and EN 50199, where the
Duty Cycle (X) is expressed as a
percentage of time the machine may
be used in a given period for a
specified welding current.

i.e. When welding at 80 Amps the
