282562

Intended Use

Welder for light to medium-duty MIG (Metal Inert Gas) welding applications, for use with
various types of steel, using suitable flux-cored welding wires. It does not require a gas
connection as the flux-cored wire provides the shielding gas in use. This product is not
designed for commercial, trade or industrial applications.

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

WARNING: Always unplug the welding machine from the mains supply and allow to
cool fully before attempting to fit or replace any part.
Note: This tool is earthed and must only be connected to mains with an earth connection.
Do not attempt to use it without an earth connection.
Assembling the mask
Assemble the mask as shown.
1. Use the Mask Clips (22) to assemble the flat-packed Welding Mask (21) into its normal
shape
2. Fit the Handle (20) using the Handle Nuts and Bolts (17 & 18). The Handle must be
inside the Welding Mask body to protect the operator's hand from splatter
3. Ensure the Safety Glass (15) protects the Welding Glass (14) from weld splatter. If the
Welding Glass is fitted as the external layer it may get damaged by splatter and allow
dangerous ultra-violet light to reach the operator's eyes
4. Fit the glass assembly into the Welding Mask using the Frame Screws (19) and Frame
Clips (16)
Installing wire
This welder requires 0.8-0.9mm flux cored wire
1. Turn the Case Lid Release (1) and lift the lid of the case 2. Turn the plastic top of the Reel Spindle Mechanism (26) anti-clockwise and remove it
carefully with the spring and top section
3. Place the supplied Wire Reel (25) over the reel holder spindle (shown already fitted),
positioning so that the Wire (27) will feed off the Wire Reel on the nearest side as
indicated by the arrow
4. Refit the top section, spring and plastic top of the Reel Spindle Mechanism. Ensure the
spring provides sufficient tension so the reel does not unravel on its own
5. Release the Tension Knob (31) so that the Tension Latch (34) can be swung clear as
shown
6. Carefully release the end of the wire from the spool and take care not to let the wire
unravel. Ensure that the wire tip is straight and is cut off cleanly
7. Slowly feed the Wire into the end of the Reel Wire Liner (32) across the Feed Roller
(30) and into the Liner (36) and push a little way into the Liner carefully
8. Swing the Tension Latch back into position, ensuring that the Wire is centred in the
grooves of the Feed Roller and Tension Roller (35)
9. Reposition the Tension Latch as shown in image A. Tension can be adjusted by rotating
the Tension Knob
10. Close the lid and secure with the Case Lid Release
11. Pull off the Shroud (9) from the torch and unscrew the Tip (23) and remove
12. Connect the welder to the mains power supply, switch on, and hold the torch
13. Move the torch away from the machine, so that the torch cable is straight
14. Ensure that the torch is not touching anything, and squeeze the Trigger (8). The wire
feed mechanism should drive the Wire through to the torch, image B
15. If the Wire is not driven through, disconnect from the mains power supply, open the
lid, and tighten the Tension Knob (31). The drive rollers should be just tight enough to
drive the Wire through to the torch, but not so tight as to prevent the drive roller from
slipping if the Wire becomes blocked
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 90/45A Switch (3)
must be set correctly. The 10% duty setting provides 90A current and the 60% duty
setting provides 45A 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
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. Set the Wire Feed Speed Dial (4) to the correct speed or to the mid-position if not sure
of correct setting, then adjust later if necessary
3. Hold the Torch Handle (7) in one hand and the Welding Mask (12) in the other
4. Position the torch so that the Tip (23) is approximately 10mm away from the metal, at
an angle of approximately 75˚
