The
thermical
effect
influence
(Joule
Effect)
is
made
by:
Current
Intensity
and
output
power
Modulation
level
Parameters
interpretable
by
the
wave
form
of
the
high
frequency
current
produced
by
the
generator.
Electrode
shape
The
electrode
shape
can
be
needle
or
rounded
according
to
the
necessity,
it
has
reduced
dimension;
for
this
the
current
density
on
the
point
surface

is
highest.
The
electrodes
with
a
thin
section
create
a
high
current
density,
and
high
temperature,
favoring
the
cut
action.
Those
with
a
big
surface
create
a
smaller
current
density,
a
smaller
temperature,
realizing
a
coagulation
effect.
State
of
active
electrode
The
thermical
effects
can
be
reported
to
the
human
body
resistance,
to
which
must
be
added
the
electrode
contact
resistance.
It’s
indispensable
to
maintain
the
active
electrodes
perfectly
clean
to
not
have
a
reduction
of
the.

of

resistive
characteristics
change
according
to
the
biological
tissues.
