The
following
is
a
list
of
terms
and
their
definitions
as
they apply
to
this
wire feeder:
General
Terms
The wire
feeder
automatically
regulates pulse
frequency
to
maintain
a
constant
arc
length,
regard
less
of
change
in
welding
wire stickout.
When weld
amperage
is
not
present,
wire feeds for about three seconds
at
set
wire
feed
speed.
Then
the
welding
power
source
contactor
deenergizes
and
wire
continues
to
feed
at
the
wire
jog
speed.
As inductance
increases,
arc on
time
increases,
and
the weld
puddle
becomes
more
fluid.
Arc
length
adjustment
in
pulse
welding.
Increasing
tnm
increases the actual
arc
length.
Trim is
re
placed by
volts
in
MIG
programs.
The
operator
programs
pulse
parameters
for
a
specific
wire feed
speed.
The wire feeder
determines
the
pulse
parameters
between these wire
feed
speed
increments.

Apk
=
Peak
Amperage
Increasing Apk
increases
penetra

Vpk
=
Peak
Voltage
Arc
voltage
during
peak
current
phase
of
the
pulse
waveform. This
determines
arc
length during
adaptive pulse
welding.

Abk
=
Background
Amperage
Maintains
arc
between
pulses.
3
PPS
=
Pulses
Per Second
Increasing
PPS increases travel
