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 (5). 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)
• Ensure that there is a qualified bystander with an operable fire extinguisher at hand
• 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
2. Hold the Electrode Clamp (5) in one hand, and the Welding Mask (9) 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 (12) 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

Maintenance
WARNING: ALWAYS disconnect from the power supply before carrying out any
inspection, maintenance or cleaning.
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
