Unpacking Your Tool

• Carefully unpack and inspect your tool. Fully familiarise yourself with all
its features and functions
• Ensure that all parts of the tool are present and in good condition. If
any parts are missing or damaged, have such parts replaced before
attempting to use this tool

Before use

• Always wear appropriate personal protective equipment for the job that
you are 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 so will not move or tip when in use. Ensure that there
is at least 500mm of clear space around the welder, to allow proper
ventilation
Operating Instructions
Warning
• Always unplug the welding machine from the mains supply and allow to
cool fully before attempting to fit or replace any part
Setting machine
• To achieve a good quality weld the Current Control Knob (1) must be
set correctly
• Turning the control knob clockwise will increase the welding current,
turning the knob anti-clockwise will reduce the welding current
Welding rod selection
• In order to produce a good quality weld, the correct type of welding rod
must be used. Welding rods are available in a variety of thicknesses and
materials and with a range of coatings
• Refer to rod manufacturers guidelines to select the correct rod for your
requirements
Duty cycle
• This machine is not designed to weld constantly. Excessive continuous
welding would cause overheating and damage to internal components
• The duty cycle (see specifications) defines the number of minutes, in
every ten minutes, that the machine can weld for
• For a duty cycle of 30%, the machine may be used for 3 minutes, then
must be allowed 7 minutes to cool
• 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
• This machine is equipped with a thermal cut-out. If the machine is
overloaded, or used beyond its duty cycle, it will automatically 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 (5) to a cleaned area of one of the parts, as near
as practical to where the joint will be
• Squeeze the Electrode Holder (4) to open the jaws. Place an electrode
into the jaws and release. The electrode should be firmly gripped with the
clamp contacting the clean metal part (not the coated part)
• Ensure that there is both a responsible person and an operable fire
extinguisher at hand
• Connect the machine to the mains power supply
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.
• Move the Power Switch (3) to the 'ON' position
• Hold the Electrode Holder (4) in one hand and the face mask in the other
• Position the rod at an angle of approx 80˚ to the surface, with the tip
approx 30mm away from the metal
• Hold the mask over your face and tap the rod against the metal
• An arc should strike between the metal and the tip. Try to hold the tip
of the rod a distance away from the metal equal to the rod thickness.
Maintain the arc for 1-2 seconds, then move the rod away
• Allow the weld to cool slightly, and move the mask away from your face.
If the settings were correct, a round 'spot' weld should have formed
• If the weld has not fully penetrated the metal, increase the current
setting. If a hole has been made in the metal, reduce the current setting
• Practice making 'spot' welds until you are confident using the machine,
and selecting settings
• To form a 'seam' weld, maintain the arc for longer, and slowly move the
rod forward at the same time. The speed at which the rod is moved is
crucial to achieving a good weld
• If the machine settings are correct, the arc should be steady, and produce
a crackling sound. Be aware that you will need to gradually move the
electrode clamp closer to the metal as the rod is used up
• Once the weld bead is complete, remove slag using a chipping hammer
or wire brush. Do not attempt to weld over beads unless properly cleaned
• Creating neat, high quality welds is a skill that takes time to master.
Practice and good preparation will help to make satisfactory welds
Maintenance
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
