IMPORTANT: DO NOT OVER-TIGHTEN THE REGULATOR ON TO THE GAS CYLINDER
Note: Any safety information provided with the regulator or gas bottle supersedes
When fitting the regulator onto the gas cylinder, check the tap valve is fully turned off and
inside the connection to the gas bottle has satisfactory seals. When fitting the regulator, it is
normal to hear a hiss of gas escape through the pressure relief hole near the bottom of the
regulator. This is to be expected and does not mean that there is a problem. The leakage will
stop as the regulator makes contact with the seal.
Do not over-tighten the regulator onto the gas cylinder as there is a risk unscrewing the
regulator will cause the cylinder to be thrust violently from your hand. When removing
regulators from gas cylinders, always do so at arm's length. Ensure that the cylinder's gas valve
is not disturbed. If you see the cylinder's gas valve start to unscrew it will be caused by an
over-tightened regulator. In these circumstances refit and retighten the regulator immediately
and discharge all gas into the atmosphere by opening the regulator valve before re-attempting
Operation
IMPORTANT
• Always wear appropriate personal protective equipment for the job that you are about to do. Use
of this machine requires a welding mask, gloves, heat-resistant clothing and, if appropriate, a
respirator
• Always ensure that you have an appropriate fire extinguisher near to the work area
• Always inspect your machine for damage or wear. Pay particular attention to leads and cables. If
any damage is found, DO NOT USE
• Check that all casings or covers are properly closed and secured
• Position the welder in such a way that it will not move or tip in use. Ensure that there is at least
500mm of clear space around the welder to allow proper ventilation

Setting the machine
• To achieve a good quality weld, the Voltage/Current Selector (7) must be set correctly. See chart
• Use Wire Feed Speed Dial (6) to make minor adjustments to wire speed to provide a steady arc.
The correct setting will depend on distance, current, torch speed, and other factors. Experiment
with wire speeds until you find an optimum setting
Duty cycle
• This machine is not designed for continuous welding. Excessive continuous welding would cause
overheating and damage to internal components
• The duty cycle defines the number of minutes, in every ten minutes, that the machine can weld
• For a duty cycle of 10%, the machine may be used for 1 minute, and then must be allowed 9
minutes to cool. The 60% duty cycle allows 6 minutes in every 10 minutes. See chart
• If the duty cycle is exceeded, the machine will automatically cut-out
• Using the machine at reduced current settings, and maintaining good ventilation will maximise
the duty cycle
Thermal cut-out
• When the thermal cut-out protection is operating, the Over-Heat Indicator (5) will illuminate and
the welder will shut down
• Allow the machine to cool. The cut-out will automatically reset once the machine is ready to be
used
Preparing to weld
• Ensure that parts to be joined are clean and free from rust, paint, or other finishes
• All parts should be well supported, so that there is a gap of approximately 1mm where you
intend to form the welded joint
• Check that there are no flammable materials in the vicinity of the work area
• Attach the Earth Clamp (9) to a cleaned area of one of the parts, as near as practical to where the
joint will be

Welding
WARNING: Using a welder correctly is a technical skill. A welder used incorrectly can be highly
dangerous. The information presented below is general guidance only. If you are not entirely
confident in your ability to use this tool safely, DO NOT USE.
IMPORTANT: Whatever type of weld you intend to make prepare carefully beforehand to make the
welding as safe, easy and accurate as possible.
1. Move the Voltage/Current Selector (7) to the required setting
2. Hold the Torch Handle (13) in one hand and the Welding Mask (36) in the other
3. Position the torch so that the Tip (10) is approximately 10mm away from the metal, at an angle of
approximately 75˚
4. Hold the mask over your face and squeeze the Trigger (12)
5. An arc should strike between the metal and the Tip. Hold the Trigger for 1-2 seconds and release
6. Allow the weld to cool slightly and move the mask away from your face. If the settings are correct,
a round 'spot' weld should form
7. If the weld has not fully penetrated the metal, increase the voltage/current setting. If a hole has
been made in the metal, reduce the voltage/current setting
• Practise making 'spot' welds until you are confident using the machine, and selecting settings
• An alternative to spot welding suitable for a MIG welder is a plug weld where the top surface
has holes drilled along a surface and a pool of the weld material fills each hole. Spot welds are
possible for thinner material with a MIG welder but the welds are more difficult and may not be
as satisfactory
• To form a 'seam' weld, hold the Trigger for longer, and slowly move the torch forward at the same
time
• If the machine settings are correct, the arc should be steady, and produce a crackling sound
• If you hear a popping sound, or struggle to maintain the arc, adjust the wire speed. If you feel the
torch trying to 'push back', reduce the wire speed
• Creating neat, high quality welds is a skill that takes time to master. Practise and good
preparation should result in satisfactory welds

Maintenance
WARNING: Always unplug the welding machine from the mains supply and allow to cool fully
6.5mm
before attempting to fit or replace any part.
Replacing tips
• As the welder is used, the Tip (10) may become worn. This will make the arc difficult to control
1. To replace the Tip, remove the Shroud (11) from the torch, and unscrew the Tip
2. Check that the new Tip is the correct size for the wire being used
3. Thread the new Tip over the end of the wire, and screw into the torch. Replace the Shroud
Cleaning
Disconnect the machine from the mains supply before cleaning
• Keep your machine clean. Always clean dust or particles away and never allow ventilation holes
to become blocked
• Use a soft brush or dry cloth to clean the machine. If available, blow through the ventilation holes
with clean, dry, compressed air
