Intended Use

Single-phase manual metal arc welder using electrode rods (sticks) to create welds in ferrous metals .
Requires a high-current 32A mains connection.
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.
Assembling the Mask
Assemble the mask as shown.
1. Use the mask clips (arrowed) to assemble the flat-packed Welding Mask (13) into its normal
shape
2 . Fit the Mask Handle (21) using the Handle Nuts and Bolts (18 & 19) . The Mask Handle must be
inside the Welding Mask body to protect the operator's hand from splatter
3 . Assemble the Filter Frame (14) with Welding Glass (15) and Splatter Shield (16) as shown .
Ensure the Splatter Shield protects the Welding Glass 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 Pins (20) and Frame Clips (17)
Connecting to mains
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 .
• This welder is not supplied with a mains electrical plug because at full capacity it will draw far too
much power for a normal domestic 230V mains plug and socket. This welder must not be fitted
with a standard 13A UK plug or 16A European plug .
• A high current 230V mains socket or terminal must be installed by a qualified and accredited
professional electrician . A 32A socket and plug conforming to IEC 60309 is recommended
• A non-socketed mains connection also requires welder connection by a qualified and
accredited professional electrician . However, a socketed connection is safer and more strongly
recommended so the welder can be safely isolated when necessary . If directly wired to mains, a
double pole, double throw isolator switch must be fitted
• The welder must be connected to a consumer unit with a built-in RCD, using a circuit protected
by an RCD
• Please refer to the Specification for details of the maximum current required by this welder
• If in any doubt, do not attempt to connect or use this welder until a professional electrician has
been consulted
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: Toxic fumes can be given off by welding and suitable respiratory protection may
be required. Read welding safety and contact your national health and safety government body for
additional information . In the UK information is available from www .hse .gov .uk/welding
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 .
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
• Turning the Current Dial clockwise will increase the welding current; turning the knob anti-
clockwise will 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 10 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 (8) 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 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
