Intended Use

Mains-powered shielded metal arc welding machine with adjustable current output. Suitable for
light duty welding tasks only .
Unpacking Your Tool
• Carefully unpack and inspect your new tool . 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: Ensure the tool is disconnected from the power supply and cool before attaching
or changing any accessories, or making any adjustments.
WARNING: Always ensure that there is an appropriate fire extinguisher near to the work area.
Mask assembly
1 . Carefully slot the Mask Handle (14) into the Handle Mount (13) and fasten securely into place
using the provided Thumb Screws (15)
2 . Fold the sides of the Face Mask (12) and clip into place
3. Remove the protective film from the lens, taking care not to scratch the lens
Connecting to a Power Supply
• Only connect this machine to a power supply capable of providing the specified voltage and
current
• If connecting to a generator, check the specification of the generator first
Welding rod selection
• In order to produce a good quality weld, the correct type of welding rod must be used. Welding
rods are available in a variety of thicknesses and materials, and with a range of coatings
• Refer to the rod manufacturer's guidelines to select the correct rod for your requirements

Operation
WARNING: ALWAYS wear a welding mask, gloves and heat-resistant clothing when working
with this tool .
WARNING: Always inspect your machine for damage or wear . Pay particular attention to leads and
cables . If any damage is found DO NOT USE .
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 .
Current selection
• In order to achieve a good quality weld, the Current Control Knob (4) must be set correctly
• Turning the Current Control Knob clockwise will increase the welding current; turning the knob
anti-clockwise will reduce the welding current
• The selected current is displayed on the Current Scale (7) and is indicated by the Current Level
Indicator (8)
• Use the Electrode Thickness Scale (9) as a guide when picking an appropriate current, other
factors such as desired weld size and material thickness also need to be considered
Duty Cycle
• This machine is not designed to weld constantly . 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 specifications) 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
• As the duty cycle limit is reached, the Thermal Overload Indicator Light (5) 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 Thermal Indicator Light 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 (11) 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 the Clamp Opening Lever (2), to open the Electrode Clamp (1). 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
Switching 'ON' and 'OFF'
• Switch the welding machine on by moving the On/Off Switch (10) into the 'I' position
• Switch the welding machine off by moving the On/Off Switch into the 'O' position
