SELECTING
THE
PROPER
STUD
COLLET
(STUD
HOLDER)
The
collet
is
selected
to
the
proper
diameter
that
you
are
welding.
There
are
three
styles
of
collets;
•
The
“B”
collet
which
is
a
two
‐
piece
assembly
(collet
and
insert).
The
insert
deter
‐
mines
how
much
of
the
stud
is
engaged
in
the
collet.
•
The
CI
(Collet
Insert)
which
is
a
single
part
and
the
amount
of
the
stud
that
is
en
‐
gaged
is
predetermined.
•
Standard
Adjustable
Chucks
have
an
adjustable
internal
screw
to
manually
adjust
for
the
engagement
of
the
stud.
The
choice
between
these
systems
is
usually
a
matter
of
personal
preference.
Inserting
the
selected
collet
into
the
stud
gun
is
a
simple
task.
Place
the
collet
into
the
front
holder
of
the
stud
gun
and
set
the
locking
screws
to
hold
it
in
place.
After
inserting
the
collet,
mount
the
two
legs
and
foot
piece
onto
the
stud
gun.
The
collet
should
be
centered
through
the
opening
of
the
foot
piece.
When
the
legs
and
foot
piece
are
in
place,
insert
the
stud
to
be
welded
into
the
col
‐
let.
Adjust
the
leg
and
foot
piece
by
sliding
it
into
position
until
approximately
1/8”
of
the
stud
protrudes
from
beyond
the
foot
piece.
Lock
legs
in
place
with
the
set
screws.
