INTRODUCTION TO STUDWELDING
7
The Taylor Studwelding DA6 HI-LIFT studwelding pistol when matched with an appropriate
controller and earth cables is intended for accurate stud welding up to 30 mm diameter
studs. The pistol is lightweight, ergonomic and has been designed to operate with a
minimum amount of maintenance. The DA6 HI-LIFT has been specically designed to have
an increased li capacity especially when welding with increased protrusion e.g. When
welding shear connectors (concrete anchors) thru-deck.
The energy required to carry out the welding operaon is derived from an appropriate
studwelding controller.
Taylor Studwelding Systems Ltd controllers are modern, robustly designed and oer
maximum reliability combined with an easy to understand operator interface.
THE PROCESS
The process of drawn arc studwelding is long established and well proven. The basic steps
are as follows :
• A measured amount of weld stud protrusion is set at the welding pistol.
• Once in posion, the pistol lis the stud away from the work-piece, simultaneously
striking an arc between the two.
• Both the p of the weld stud and the surface of the work-piece melt as the arc is
sustained for a pre-determined interval.
• At the compleon of the pre-determined interval, the pistol returns the weld stud to
the molten pool on the work-piece, thus forming a weld.
The most common and tradional drawn arc welds have a weld duraon greater than
100ms and employ the use of a single use ceramic arc shield, commonly referred to as a
ferrule. This ferrule helps to protect the arc during the weld and assists in formaon of the
nal llet. Post welding the ferrule is removed and disposed of.

SETTING UP AND WELDING

Select the type and size of stud you wish to weld and obtain the correct chuck and foot
arrangement (see below and the accessories secon of this guide for a list of available
sizes).
Standard shear connector chucks screw directly
onto the thread on the pistol sha. The chucks
normally have a cross drilled hole in order that a
bar can be inserted for ghtening or have
machined ats to take a wrench.
IMPORTANT! Make sure the chuck is ed
securely. Failure to do so may result in damage to both the chuck and the pistol sha
during welding.
IMPORTANT! Ensure that when ng the chuck that the cable aachment to the sha is
not loosened, as this also may result in damage
during welding.
An assortment of front end opons are available
(see g.1 - 3 right) and which of these would be
preferable is down to customer choice when
ordering. All three opons shown perform the
same task but are beer suited to parcular
applicaons.
Fig.1 shows an extended foot arrangement which
is favoured by many when performing thru-deck
welding. This foot arrangement allows studs and
ferrules to be placed in areas with limited access.
Fig.2 shows an arrangement more suited in “to
beam” welding where condions and access are
generally easier.
Fig.3 shows a budget arrangement which is
available for lower volume work.
This pistol is commonly referred to as a “ring li”
pistol. This is because the li mechanism in the
pistol includes a clutch assembly with a lng ring. What this means in praccal terms is
that not only can the li can be adjusted within its operaonal limits, should certain
parameters change from weld to weld, for example the studs being welded varying in
length slightly, the pistol will be able to allow for this without aecng the li that has been
set. Even so, we recommend that only properly manufactured weld studs be used to ensure
repeatable weld quality.

SETTING UP AND WELDING

Fit the stud and ferrule in place and set the
required burn o protrusion. This is achieved
by using a 5mm hex key to loosen the leg
clamps in the front end cap.
Aer loosening the clamps, slide the legs in or
out unl the desired stud protrusion is
achieved (this amount will vary from stud size
to stud size and is generally proporonal to the
stud diameter).
NOTE! In the BS EN ISO standard covering the
manufacture of drawn arc weld studs, the
length prior to welding (this is the length aer
welding plus the burn o allowance) is at the
discreon of the stud manufacturer.
Dierences in this length would impact on the
burn o protrusion value.
As a general rule of thumb, we would suggest that the burn o protrusion distance should
be approximately 8 to 10mm, but never less than 7mm.
Once the correct protrusion is set, you must
ensure that the movement of the stud inside
the ferrule is smooth, as any binding between
the stud and ferrule will result in poor or bad
welds. As can be seen in the accompanying
illustraon where the foot piece is shown with
some of the fasteners missing, the holes in the
foot piece are a lot bigger than the screws
fastening the foot piece to the legs. This allows
the foot piece to be adjusted to remove any binding between the stud and ferrule. Once
these condions are sased, you are now
ready to set the li.
IMPORTANT!
It is necessary to check/reset the protrusion
and posioning of the foot adaptor when
changing stud lengths/diameters.
SETTING THE LIFT
Adjustment of the pistol li is achieved by removing the rear end cap of the pistol. Inside is
an adjuster with a large slot. Use a coin to twist the adjuster. Clockwise rotaon reduces li
and conversely an-clockwise rotaon increases li. The adjuster has a “click” detent, each
click is approximately equal to a 0.25mm change in li.
Li should be set between 1mm and 8mm depending on the size of stud being welded and
other applicaon specic factors e.g. material, site condions etc.

Once the required li has been set, the pistol is now ready to weld and can be connected to
the controller. Consult your appropriate controller operang guide for assistance in seng
up the controller.
Other useful informaon including stud welding techniques, weld tesng and inspecon
can also be found in the controller operang guide.
PLEASE NOTE. Informaon contained in this operang guide is intended to assist in seng
up and using the pistol. All the suggested sengs are intended as a starng point only. Fine
tuning the sengs to achieve the most sasfactory results is essenal and is the
responsibility of the user of the pistol.
