The
slope
reactor
)Z),
located behind the left
rear
tide
panel,
has three
sets
of five
slope
reactor
coil
taps.
An increase
or
decrease
in
slope
may
be deemed
necessary
with
a
particular
43
Gas
Metal-Arc
Welding
process. An increase in
slope
results in
lets available short circuit
welding
current
and slower
welding
response. The
slope
connections
are
positioned
for 0
turns
(OT) slope (no
slope),
upon
shipment.
To
change
the
slope
connections, proceed
as
follows:
(See
Figure
3-4 for
slope
reactor
coil
tap connections.)
1.
Open
the
left
rear
side
panel
to
obtain
access
to
the
slope
reactor
coils.
2.
Disconnect leads
43,
44,
and 45 from the
slope
reactor
coil taps.
3.
Reconnect leads
43, 44,
and 45
to
the desired
slope
re
actor
coil taps.
IMPORTANT
Ensure that leads
43, 44,
and 45
are
connected
to
the
same
value reactor
coil tap. Ensure also that leads
43,
44.
and 45
are
reconnected
to
the
same
reactor
coil
from which these leads
were
disconnected.
