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
Disposal
• Do not dispose of power tools, or other waste electrical and electronic
equipment, with household waste.
• Contact your local waste disposal authority for information on the correct
way to dispose of tools
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 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
iscrucial 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 have to gradually move the
electrode clamp closer to the metal as the rod is used
• Once weld bead is complete, remove excess and splatters 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
Troubleshooting
Should you experience any problem with the welder please make the
following checks:-
• That the welding current is correct for the diameter and type of electrode
in use
• That if the power supply is on, the power indicator light in the ON/OFF
switch is on. If the power indicator light is not on there is a power supply
problem (for example a circuit breaker may have blown)
• That the correct voltage is being used as indicated on the rating plate
• That you have not exceeded the duty cycle and the thermal cut-out is
in operation
• That the cables are undamaged and that there is nothing causing a
short circuit
• That all circuit connections are correct. You should pay particular
attention to the work clamp, making sure that it is correctly attached to
the workpiece and that there is no grease, paint or other contaminate
that could cause a bad connection
