Innershield (FCAW-SS) with LN-25
Wire Feeder
Connection Of The LN-25 To The Titan
CAUTION
Shut off welder before making any electrical connections.
The LN-25 with or without an internal contactor may be used with
the Titan.
NOTE: The LN-25 (K444-1) Remote Control Module (k431) and
Remote Cable (K432)cannot be used with the Titan.
•
Shut the welder off.
•
For electrode Positive, connect the electrode cable from the
LN-25 to the "+" terminal of the welder and work cable to
the "-" high inductance terminal of the welder. For electrode
Negative, connect the electrode cable from the LN-25 to
the "-" high inductance terminal of the welder and work
cable to the "+" terminal of the welder.
•
Switch the CC/CV switch located above the wire feed motor
on the LN-25 to CC. (Refer to LN-25 Operator Manual for
setting welding parameters).
•
Attach the single lead from the front of the LN-25 to work
using the spring clip at the end of the lead. This is a sense
lead to supply current to the wire feeder motor; it does not
carry welding current.
•
When the gun trigger is closed, the current sensing circuit
will cause the wire to begin to feed and the welding process
is started.
WARNING
The LN-25 sensor has full OCV potential between spring
clip and work return. Turn machine off when attaching
spring clip.
WARNING
If you are using an LN-25 without an internal contactor, the
electrode will be energised when the Titan is started.

Arc Gouging
For optimal performance use Titan's Low Inductance (-) output
stud.
Set the "OUTPUT" fine and Course controls to adjust output
current to the desired level for the gouging electrode being used
according to the ratings in the following table:
Auxiliary Power Operation
Start the engine. Set fine Output Control to maximum for best
auxiliary operation.
The auxiliary power of the Titan consists of one 15 Amp 230/240V
single phase receptacle.
The auxiliary power capacity is 3,400 watts of 60 Hz, single phase
power. The auxiliary power capacity rating in watts is equivalent to
volt-amperes at unity power factor. The maximum permissible
current of the 230 VAC output is 15 A. Output voltage is within ±
10% at all loads up to rated capacity.
The auxiliary power receptacles should only be used with three
wire, wire earth type plugs or approved double insulated tools
with two wire plugs.
The current rating of any plug used with the system must be at
least equal to the current capacity of the associated receptacle.
Simultaneous Welding and Auxiliary
Power Loads
It must be noted that the above auxiliary power ratings are with no
welding load. Simultaneous welding and power loads are
specified in table B.4. The permissible currents shown assume
that current is being drawn from the 230/240 VAC.
