Note: Before use, check that all casings or covers are properly closed and
secured.
Note: Position the welder to ensure 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.
Switching on and off
• Switch the welding machine on by moving the On/Off Switch (2) (located at
rear of welder) into the 'I' position
• Switch the welding machine off by moving the On/Off Switch into the 'O'
position
Current selection
• In order to achieve a good quality weld, the Current Dial (3) must be set
correctly
• Turn the Current Dial clockwise to increase the welding current; turn the
knob anti-clockwise to reduce the welding current
Duty Cycle
• This machine is not designed to weld constantly at higher current settings.
Excessive continuous welding will cause overheating and damage to internal
components
• 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
• The duty cycle (see Specification) defines the number of minutes in every ten
minutes that the machine can weld
• 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
• When the duty cycle limit is reached, the Over-Heat Indicator (6) will
illuminate. The light will cut out when the machine has cooled and is ready
to be used again
• As a precaution, it is recommended the machine is allowed to cool for a
further three minutes after the Over-Heat Indicator has switched off, to
ensure the cool-down temperature has been met
Weld preparation
• Ensure the joining surfaces of the workpiece are clean, free from rust, paint,
or other finishes
• All parts should be well supported, with a gap of approximately 1mm where
the weld is intended to be formed
• Check that there are no flammable materials in the vicinity of the work area
• Attach the Earth Clamp (6) to a cleaned area of one of the parts, as near as
practical to where the joint will be
Note: Improve connectivity between the Earth Clamp and the workpiece by
wrapping a piece of scrap copper wire, with the insulation removed, around the
teeth of the clamp.
• Squeeze lever, to open the Electrode Clamp (10). Place an electrode into the
jaws, and release. The electrode should be firmly gripped with the clamp
contacting the clean metal part of the rod (not the coated part)
• Connect the machine to the mains power supply
Welding
WARNING: Using a welder correctly is a technical skill. An incorrectly-used
welder can be highly dangerous. The information below is general guidance only.
If you are not entirely confident in your ability to use this tool safely DO NOT USE.
1. Move the On/Off Switch (2) into the 'I' position (located at rear of welder)
2. Hold the Electrode Clamp (10) in one hand, and the Welding Mask (13) in
the other
3. Position the rod at an angle of approximately 80˚ to the surface, with the tip
approximately 30mm away from the metal
4. Hold the Welding Mask over your face and tap the rod against the metal
5. An arc should strike between the metal and the tip. Try to maintain a
distance between the welding rod and the workpiece equivalent to the
diameter of the rod. Maintain the arc for one-to-two seconds, then move
the rod away
6. 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
7. 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

8. Practice making 'spot' welds until you are confident in using the machine
and selecting settings
9. In order to form a 'seam' weld, maintain the arc for longer and slowly move
the rod along the path of the join. 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 should
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 up
• Once the 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
Accessories
• A range of other accessories and consumables, including Welders Helmet
(868520, 934295 and 757060), Welders Chipping Hammer (515858),
Welders Apron (633505) and Welders Gauntlets (282389), is available from
your Silverline stockist. Spare parts can be obtained from

Maintenance
WARNING: ALWAYS disconnect from the power supply before carrying out
any inspection, maintenance or cleaning.
• If the mains cable becomes damaged or worn it must be replaced by a
qualified technician, with a cable equal or superior in current capacity to the
original fitted cable
• If the internal fuse blows, it must be replaced with a fuse of exactly the
same type and rating as originally fitted. If the replacement fuse blows
immediately, it is likely to indicate a fault condition and a service technician
should be consulted immediately
General inspection
• Regularly check that all the fixing screws are tight
• Inspect the supply cord of the tool, prior to each use, for damage or wear.
Repairs should be carried out by an authorised Silverline service centre. This
advice also applies to extension cords used with this tool
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts
to wear quickly, and shorten the machine's service life. Clean the body of
your machine with a soft brush, or dry cloth. If available, use clean, dry,
compressed air to blow through the ventilation holes
• Clean the tool casing with a soft damp cloth using a mild detergent. Do not
use alcohol, petrol or strong cleaning agents
• Never use caustic agents to clean plastic parts
Storage
• Store this tool carefully in a secure, dry place out of the reach of children
Disposal
Always adhere to national regulations when disposing of power tools that are no
longer functional and are not viable for repair.
• Do not dispose of power tools, or other waste electrical and electronic
equipment (WEEE), with household waste
• Contact your local waste disposal authority for information on the correct
way to dispose of power tools
