the latch down and allowing the
side panel to drop down.
2. Remove any loose items that
have been transported inside
such as the handle, wheel kit etc
THE WELDING SHIELD
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.
5. The clear glass panel should be replaced when it becomes badly pitted.
1. Thermal overload light. If the duty cycle is exceeded as a result of welding
too long with a high current, the yellow overload light will illuminate and the
welder will turn off. When the welder has cooled down (approx. 5 to 10
minutes), the power will be restored and welding can recommence.
2. Power ON/OFF switch. When the power is ON the green switch will be
illuminated. When the welder is no longer required, the Power On/Off switch
should be switched to the OFF position and the plug should be disconnected
from the mains supply.
3. Current setting switches MIN-MAX & 1-2. Used together these two switches
provide 4 increasing power levels as follows:
•MIN-1
•MIN-2
•MAX-1

4. Wire speed control knob. As a general rule, a higher current requires a
1. Loosen the tensioning knob and
pivot it towards you
2. Lift up the arm.
3. Take hold of the triangular knob
on the drive roller cover and
rotate it 90°anticlockwise to
release it.
4. Pull the roller retainer off the drive
spindle to reveal the roller.
5. Pull the roller off the drive spindle.
• The groove size is stamped on
the corresponding side of the
roller. Select the groove size
according to the size of the
wire you are using and put the
roller back on the spindle with
your chosen side facing you.
6. Replace the drive roller cover
back onto the drive spindle with
the opening facing right.
7. Ensure that the flanges at the base of the drive roller cover, seat fully into
the circular recess in the main moulding and then rotate the drive roller
cover through 90° to lock it in place.
THREADING THE WIRE
IMPORTANT: Do not release the tension on the wire as it will unravel causing
feeding problems later.
1. Pull out the end of the wire from the spool, taking care not to release the
tension.
• We recommend you cut off and discard the first 10 cm of wire from
the spool to avoid burrs and then straighten the next 15 cm of wire
to help with feeding.
2. Loosen the tensioning knob and pivot it towards you.
MIG (Metal Inert Gas) welding allows you to fuse together two similar metals
without altering the properties of the metal.
A consumable wire electrode is continuously fed through the welding torch
that is fitted with a concentric gas nozzle. the wire is connected to a high
voltage supply which creates an electric arc between the electrode (the
wire) and the workpiece. The arc is used to create the required heat to turn
the metal into a molten state. The wire is used as both the electrode and as a
filler.
The gas is used to prevent oxidation and to shield the arc and the weld from
atmospheric contamination. The choice of gas is dependent upon the
material being welded, Two types are available from Clarke International.
Carbon Dioxide (CO
CO2/Argon Mix
When using the welder in a gasless configuration the shielding gas is created
from the flux within the welding wire.
When using the welder outside, you may need to erect a wind break to make
sure the shielding gas is not blown away, thereby leaving a poor quality weld.

GAS/NO-GAS SELECTION
The welder can be configured to
weld, with or without a gas supply
according to the type of welding
wire being used.
1. If using 0.9mm flux cored wire,
connect the terminal as shown.
• The earth cable (Thicker Lead)
should be connected to the
positive (Red) terminal.
• The cable from torch (Thinner
Lead) should be connected to
the Negative (Black) terminal
WELDING WITH GAS
1. If using solid cored wire 0.6/0.8mm
mild steel, connect the terminal as
shown.
• The earth cable (Thicker Lead)
should be connected to the
negative (Black) terminal.
• The cable from torch (Thinner
Lead) should be connected to
the positive (Red) terminal.
CONNECTING THE GAS SUPPLY
2. Connect a bottled gas supply to
the small tube at the back of the
welder.
OPERATING THE WELDER
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.
Attach the earth clamp to the workpiece as close to the point of weld as
possible, without it being intrusive.
CAUTION: THE DUTY CYCLE MUST BE ADHERED TO TO PREVENT THE
THERMAL OVERLOAD PROTECTION FROM ACTIVATING
1. With the welding current set and the wire trimmed, set the wire feed
control to 6.
2. Plug the machine into the mains supply and switch ON the machine.
3. Cover your face with a welding mask or welding helmet.
• This is essential.
4. Lower the torch to the workpiece with one hand and approach the work
with the torch tip at an angle of about 35
• As the wire touches the workpiece, an arc will be struck.
5. In order to produce a satisfactory weld, the controls may be fine tuned as
required. This will come with practice.
NOTE: MIG welding is an acquired skill, it is strongly advised that, if you
are not fully familiar with this type of welding, you practice on a
piece of material with the same characteristics as your
workpiece, until you are satisfied with the result, and you have
fine tuned your welder to produce a satisfactory weld.
NOTE: One of the problems experienced with novice welders, is the
welding wire sticking to the contact tip. This is as a result of the
wire feed speed being too slow. It is always better therefore to
start with too high a speed, and back off slightly, to avoid the
possibility of the wire welding itself to the tip. This is the reason
position 6 is recommended for start up.
NOTE: The Wire Feed control is for fine tuning the wire speed. The speed
of wire delivery will increase automatically as the current is
increased. Therefore, once the ideal speed is achieved by fine
tuning, it should not be necessary to adjust this control when the
welding current is changed.
NOTE: Listen to the sound made. An irregular crackling sound denotes
too high a wire speed. Decrease the speed until a regular, strong
buzzing sound is heard.
The ‘Thermal Overload’ shuts off the
welder when it becomes too hot,
due to the duty cycle being
exceeded. This is to prevent any
damage to the machine.
When this occurs, the warning lamp
shown will glow (amber). Allow the
welder to cool, until the amber light
extinguishes before resuming work.
DUTY CYCLE
These welders are covered by
regulations EN 60974-1 and EN 50199,
where the duty cycle is expressed as
a percentage of time the machine
may be used in a given period for a
specified welding current.
Using the example shown, which is an
illustration of the data plate;-
e.g. when welding at 72 amps the
machine may be used for 3.5 minutes
(35%) in any 10 minute period.
WARNING: ELECTRICITY CAN KILL - NEVER TOUCH LIVE ELECTRICAL
COMPONENTS.
WARNING: DISCONNECT THE POWER SUPPLY BEFORE ALL INSPECTIONS
AND MAINTENANCE OPERATIONS. BEWARE HOT SURFACES.
WARNING: ALWAYS LET THE WELDER 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 environments etc).
Always inspect the earth cable 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.
Check the hose for security and damage.
As a general rule the power supply should be inspected at least annually.
Consult your CLARKE dealer for advice if necessary.
Wire feed unit:
The feed roller wire guide plays an important part in obtaining consistent
results. Clean the rollers weekly, especially the feed roller groove, removing all
dust deposits.
Torch:
Protect the torch hose assembly from mechanical wear. Clean the liner from
the machine forwards by using compressed air. If the liner is blocked it must be
replaced.
Contact tip:
The contact tip is a consumable item and must be replaced when the bore
becomes enlarged or oval. The contact tip MUST be kept free from spatter to
ensure an unimpeded flow of gas.
To keep the contact tip free from spatter, we recommend the use of antispatter spray (MIG/6000715) available from your CLARKE dealer.
Torch shroud:
The torch shroud must also be kept clean and free from spatter. Build-up of
spatter inside the gas cup can cause a short circuit at the contact tip which
will result in expensive machine repairs.
