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 fire and burns. Appropriate clothing must be worn. Clothing
made from, or soiled with, combus�ble materials must NOT be worn.
Have a fire ex�nguisher nearby and know how to use it.
Magne�c fields from high currents can affect 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.
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 fire.
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.

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 specifically designed to enable
a small diameter range of ferrous and non‐ferrous weld studs to be welded to light gauge,
self‐finish 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 film 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.

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 fi�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 fi�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
V‐4J
SETTING UP AND WELDING
11
Connect the welding pistol control cable to the
panel mounted socket on the controller.
Note that the cable end plug and panel moun�ng
socket are keyed to prevent incorrect fi�ng. Push
the plug firmly home and twist the locking ring
clockwise to secure the plug in posi�on.
Prepare the pistol for use in accordance with the guidance given in the document
“OPERATING GUIDE FOR CD STUDWELDING PISTOLS TYPE C2 & LG2” which accompanies

This page and the following are intended as a guide to se�ng your machine.
The se�ngs outlined in the table are only intended as a star�ng point. It is possible that the
se�ngs will give sa�sfactory results without adjustment, but in reality the quality of the
welding results is governed by many variable factors. These include, most obviously, the
welding power and pistol spring pressure as covered in the table, but can also include
factors such as stud and work‐piece material type and condi�on, ambient temperature,
rela�ve humidity, quality of supply etc. All of these factors can act on the weld to change
the outcome. It is recommended that in all instances, you need to carry out sample welds
in your actual condi�ons and environment. This will enable you to alter the se�ngs, where
necessary, to achieve welds that are most acceptable to you.
The se�ng charts were established with the performance of repe��ve weld tests using
studs manufactured to the BS EN ISO 13918 standard, in the following materials :
Mild Steel, Grade St37‐3
Stainless Steel, Grade 1.4303
Aluminium Alloy, Grade AlMg3
and sheet materials of the following types :
1.6 mm Thick, Mild Steel, Grade CR4
1.6 mm Thick, Stainless Steel, Type S304
1.6 mm Thick, Aluminium Alloy, Grade HE30, Half Hard

WELD TESTING
14
Visual examina�on of weld quality can, even with limited experience, provide a useful
quality assessment. In such a check the presence of a small even witness of weld material
around the base of the stud flange a�er welding should be ensured. Poor welds are
indicated by excess metal on one side of the welded flange and / or the presence of an
undercut or non‐fused area between the stud flange and the parent sheet or plate.
Incorrect se�ngs, adverse magne�c effects etc. such as those at edge welding posi�ons or
with unbalanced earths and studs welded to the work piece at an angle, the controller and
pistol should be examined with a view to correc�ng such defects.
MECHANICAL TESTS :
1. BENDING.
The most easily applied method of tes�ng the quality of welded fasteners considered here,
involves the use of a bending bar. This bending bar (available from your supplier, see the
accessories sec�on of this manual) fi�ed with the correct size of nozzle for the stud to be
tested is used to bend over the stud in accordance with BS EN ISO 14555:2006
specifica�on.
2. TORSION.
A torsion test provides useful informa�on for threaded fasteners. This involves �ghtening a
nut on the stud against a spacer, suitably relieved to cater for the flange and weld spa�er.
For quan�ta�ve assessments a suitably calibrated torque wrench may be used, but at its
simplest, a spanner will suffice.
In the above tests the performance of the welded joint should be considered in rela�on to
the thickness of the material to which the stud is welded. On thicker materials, a full
strength weld is denoted by deforma�on or failure of the stud shank. On lighter gauge
material, severe "dimpling" or "dishing" at the reverse to the weld side normally indicates
sufficient strength, whilst in most cases, the tearing of a slug of material from the parent
sheet will occur.
