16. When the Wire is propelled out of the end of the torch, switch off and disconnect from the
mains power supply
17. Refit the Tip and the Shroud, and trim the Wire so that approximately 5mm projects from the tip
Removing wire reel and end of wire
1. Open the lid of the welder using the Case Lid Release (1)
2. Use a pair of pliers to draw the last of the old Wire Reel out through the Tip (15) of the torch. If
the old Wire Reel (25) is not empty, cut the wire at the spool and release the Tension Knob (31)
and move the Tension Latch (34) away from the Feed Roller (30)
3. Then proceed as per instructions for 'Installing wire' above
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
Operation
WARNING: Always unplug the welding machine from the mains supply and allow to cool fully
before attempting to fit or replace any part.
Setting the machine
• To achieve a good quality weld, the Wire Feed Speed Dial (4) and 120/60A Switch (3) must be
set correctly. The 10% duty setting provides 120A current and the 60% duty setting provides
60A current
• The wire speed should be adjusted 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
Note: The welder optimises current output depending on wire speed and monitored current levels
to improve weld quality and reduce splatter.
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
• 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 (11) to a cleaned area of one of the parts, as near as practical to where
the joint will be
• 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.
1. Move the On/Off Switch (2) to the 'ON' position
2. Hold the Torch Handle (7) in one hand and the Welding Mask (12) in the other
3. Position the torch so that the Tip (23) is approximately 10mm away from the metal, at an angle
of approximately 75˚
4. Hold the mask over your face and squeeze the Trigger (8)
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 setting. If a hole has been
made in the metal, reduce the voltage 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
Accessories
• A range of accessories including personal protective equipment and welding tools are available
from your Silverline stockist. Spare parts can be obtained from toolsparesonline.com
Maintenance
WARNING: Always unplug the welding machine from the mains supply and allow to cool fully
before attempting to fit or replace any part.
Replacing tips
• As the welder is used, the Tip (23) may become worn. This will make the arc difficult to control
1. To replace the Tip, remove the Shroud (9) 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
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 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
