Disconnecting the Remote plug from this recepta-
cle automatically transfers output control back to
the panel Output Control (item (2) above).
Remote output On/Off switching can also be done
through this Remote Control receptacle by per-
forming the following wiring changes:
1. Making sure the input to the Converter is
removed, remove the case wraparound.
2. Locate the 4-pin plug (P21) on the back panel
of the control box module, and cut the jumper
lead looping from the back of the plug. (Refer to
the Wiring Diagram in the Electrical Diagrams
section.) Insulate the cut lead ends and leave
long enough to possibly splice back together
again at some future time.
3. Replace the case wraparound.
4. Connect a user-provided remote switch be-
tween pins D and E of an MS3106A-18-12P
plug (Lincoln part no. S12020-27 with S12024-
1 cable clamp). See the diagram below:

PARALLELED CONVERTERS
Multi-Weld 350 converters that are paralleled (see INTER-
CONNECTION OF CONVERTERS in the Installation
section) must each be set up in the same manner in order
to manage the arc current drawn from each:
1. Set to CC mode with CC SLOPE switch set to
STICK/GOUGE.
2. Preset
Output
Controls
Converters to ~1/2 desired total AMPS.
If arc current from each Converter gets too out of bal-
ance (primarily a problem if trying to use CV mode) the
hotter running Converter could go into current-limiting
and/or Thermal shutdown (See OVER-TEMPERA-
TURE SHUTDOWN in the Installation section.) This
might then overload the other, or at least interrupt the
operator's process. However, no damage will occur to
the Converters.
REMOTE CONTROL OF
PARALLELED CONVERTERS
(FOR CC STICK/GOUGE MODE ONLY)
Full Range remote control can be accomplished with a
separate optional Remote output control (see the
Installation section) connected to each Converter. The
current contribution of each Converter will depend on
its remote output setting.
Partial Range remote control can be accomplished with
a single Remote Control connected to the output
Converter. The input Converter must be preset with its
panel Output Control to below the minimum desired
output range. The Remote Control, connected to the
output Converter, will control its output to add to the
preset level.
Remote Output On/Off switching may be set up for
each of the paralleled Converters. Electrically isolated
switches must be used to activate each separately but
simultaneously.
TRANSPORTING AND STORAGE
OF THE MULTI-WELD 350
CABLE HANDLING
The input and electrode cables are easily disconnect-
ed from the quick-connect "pig-tails." The Work lead
can be reeled around the Multi-Weld 350 case cradled
by the base skid handles, to which the clip can be
secured.
