PROTECT YOURSELF AND OTHERS !
Read and understand these safety notes.
1. ELECTRICAL
No poron of the outer cover of the welding controller should be removed by anyone other
than suitably qualied personnel and never whilst mains power is connected. ALWAYS
disconnect the mains plug from the socket.
BE AWARE ! Capacitors store electrical energy. Check for residual
charge before carrying out any internal maintenance.
DO NOT ! use any uids to clean electrical components as these
may penetrate into the electrical system
Installaon must be according to the seng up procedure detailed on page 10 of this
manual and must be in line with naonal, regional and local safety codes.
2. FIRE
During welding small parcles of very hot metal are expelled. Ensure that no combusble
materials can be ignited by these.
3. PERSONNEL SAFETY
Arc rays can burn your eyes and skin and noise can damage your hearing. Operators and
personnel working in close proximity must wear suitable eye, ear and body protecon.
Fumes and gases can seriously harm your health. Use the equipment only in a suitably
venlated area. If venlaon is inadequate, then appropriate fume extracon equipment
must be used.
Hot metal spaer can cause re and burns. Appropriate clothing must be worn. Clothing
made from, or soiled with, combusble materials must NOT be worn.
Have a re exnguisher nearby and know how to use it.
Magnec elds from high currents can aect heart pacemakers or other electronically
controlled medical devices. It is imperave that all personnel likely to come into the vicinity
of any welding plant are warned of the possible risks before entering the area.
To minimise the risks of exposure to electromagnec radiaon, operators should not drape
the welding cables over their shoulders or wrap them around themselves in any way whilst
using the equipment. It is also recommended that operators route the welding earth return
cables away from themselves and do not stand between the two earth return cables during
welding.

4. MAINTENANCE
All cables must be inspected regularly to ensure that no danger exists from worn or
damaged insulaon or from unsound electrical connecons. Special note should be made
of the cables close to the pistol, where maximum wear occurs. As well as producing
inconsistent welds, worn cables can overheat or spark, giving rise to the risk of re.
5. LIMITATIONS OF USE
The mass of the welding controller is between 11 and 13.3kg dependant on the model
purchased and as such is suitable to be manhandled. The controller is not suitable for use in
rain or snow or in an environment with increased risk of electric shock.
6. TRAINING
Use of the equipment must be limited to authorised personnel only who must be suitably
trained and must have read and understood this manual. This manual must be made
available to all operators at all mes. Further copies of this manual may be purchased from
the manufacturer. Measures must be taken to prevent the use of this equipment by
unauthorised personnel.
7. INSTALLATION
Ensure that the site chosen for the equipment is able to support the weight of the
equipment and that it will not fall or cause a danger in the course of its normal operaon.
Do not hang connecng cables over sharp edges and do not install connecng cables near
heat sources or via trac routes where people may trip over them or they may be
damaged by the passage of vehicles (forklis etc.)
8. INTERFERENCE
During welding operaons, intense magnec and electrical elds are unavoidably produced
and these may interfere with other sensive Electronic equipment.
All Taylor Studwelding equipment is designed, manufactured and tested to conform the
current appropriate European standards and direcves regarding electromagnec
emissions and immunity and as such is safe to use in any normal environment.
9. DISPOSAL
The equipment either wholly or any of its component parts may be disposed of as part of
general industrial waste or passed to a scrap merchant. None of the components used in
the manufacture are toxic, carcinogenic or harmful to health in their “as supplied”
condion.

INTRODUCTION TO STUDWELDING
7
INTRODUCTION
The complete range of Taylor Studwelding Systems Capacitor Discharge units are
compact, portable Stud Welding equipment's. The units are specically designed to enable
a small diameter range of ferrous and non-ferrous weld studs to be welded to light gauge,
self-nish or pre-coated materials, in most cases with lile or no reverse marking.
The equipment consists of a control unit, a welding pistol and the necessary
interconnecng cables and accessories.
THE PROCESS
Capacitor Discharge stud welding is a form of welding in which the energy required
for the welding process is derived from a bank of charged capacitors. This stored energy is
discharged across the gap between the two surfaces to be welded as they are propelled
towards each other. The arc produced heats the two surfaces, melng a thin lm of metal
on each surface and the propelling force closes the gap between the two faces, thus
forming a weld.
In contact welding the stud to be welded is forced by spring pressure on to the plate.
At this point the arc gap between the two components is maintained by a small pip on the
welding face of the stud. On iniaon of the high current pulse from the capacitors, this pip
vaporises and an arc is drawn between the work piece and the stud. The heat from this arc
melts the base of the stud and the area of the work piece directly beneath the stud, whilst
the spring pressure from the pistol accelerates the stud towards the work piece. Within 3
to 4 milliseconds the stud hits the work piece and the arc is exnguished. The kinec
energy contained in the moving stud and the remaining spring pressure, forge the molten
parts together to form a weld.

IMPORTANT NOTES !
Due to the power requirements and Electromagnec emissions produced during normal use, this
machine must only be operated in an industrial environment.
The unit has inverter technology and is designed to operate from any single phase AC voltage between
100 and 250VAC at 50Hz.
Never obstruct the front and rear panel venlaon holes or the underside of the unit as this may cause
the unit to overheat during operaon.
Never remove any poron of the unit housing without rst isolang the unit from the mains electrical
supply.

SETTING UP AND WELDING
10
Set up the control unit at the place of work,
ensuring that the mains switch is in the OFF
posion. Ensure that this is done in line with the
notes and safety recommendaons on pages 5 and
6 of this manual.
Plug the controller into the
correct mains AC supply. The
controller is rated for any single
phase AC voltage between 100
and 250VAC at 50Hz. Ensure
the correct plug is ed for
your supply in line with local/
naonal codes.
Connect the welding earth cable to the controller panel
mounted plug.
Note that the cable end plug has a peg which mates with a
key slot in the panel mounted socket.
IMPORTANT !
Secure the connector with a
clockwise turn unl it locks.
Failure to do this will result in
damage to the connector
during welding.
Aach the welding earth clamps to the work piece at
approximately 180° to each other. This will help to prevent
"Arc blow" when welding takes place. Prior to ng the
clamps, ensure that the contact area of the work piece is
free from rust, paint, grease etc. As this will result in a poor
welding connecon and poor results. Where possible, route
the earth cables away from the operator to prevent the operator being posioned between
the run of the cables whilst operang the equipment.
Connect the welding pistol cable to the controller panel
mounted socket.
Note that the cable end plug has a peg which mates with
a key slot in the panel mounted socket.
IMPORTANT !
Secure the connector with
a clockwise turn unl it
locks. Failure to do this
will result in damage to
the connector during
