OUTPUT CABLES, CONNECTIONS
AND LIMITATIONS
The Multi-Source has two parallel connected output
studs for positive and negative connections. Each one
is rated to carry the full output current. For its maxi-
mum rated current at 100% duty cycle a minimum size
of 4/0 AWG is recommended.
Connection of Electrode and Work Leads to
Output terminals.
1. Set the POWER ON/OFF Toggle Switch to OFF.
2. Raise the hinged cover protecting the output termi-
nals.
3. Insert the electrode lead up through the elliptical
hole in the machine base below the positive output
terminal. Pull through enough cable to reach the
output terminal.
4. Connect electrode lead to the terminal .
5. Tighten the output terminal nut with a wrench.
6. Connect the work lead to the negative output termi-
nal following steps 3-5.
7. Lower the cover to protect the output terminals.
RECOMMENDED EQUIPMENT AND
PROCESSES
The only recommended use for the Multi-Source is to
power the Multi-Weld welders. It is conceivable that
the machine could be used as a constant voltage DC
power supply up to its rating of 40,000 watts (36,000
watts on 50Hz) output. Its output is stable with a wide
range of inductive, resistive and capacitive loads but
each application would have to be tested. The output
is peak voltage regulated and at light resistive loads
(maximum ripple) the average voltage deviates from
peak voltage the most.
MULTI-SOURCE
The Multi-Source 40kW (36kW on 50Hz) 80VDC buss
power source (K1752-1) is recommended for use in
the Multi-Weld system. The number of Multi-Weld
Converters that may be connected to a single Multi-
Source Power Source is determined by the following
formula:
Power Source (Volts x Amps) capacity > 1.1 x Sum
of Converters’ (Volts x Amps) arcs
RECOMMENDED EQUIPMENT / INTERFACE
The Multi-Weld 350 (K1752-1) is the recommended
means by which to control the Multi-Source power
supply. Connections between Multi-Source and Multi-
Weld may be easily made using Twist-Mate male and
female connectors and the K1736-1 Distribution Box.
The Multi-Weld 350 has multi-process capability and
may be used manual and semi-automatic processes.
When a wire feeder is required an LN-25 (K449) is
recommended.
EQUIPMENT LIMITATIONS
The number of Multi-Weld 350s, the procedures used
and the combined duty cycle of the arcs are only limit-
ed by the 40,000 (36,000 watts on 50Hz) watt rating of
the Multi-Source supply. The machine is IP-23S rated
and is designed for outdoor applications.
DISTRIBUTION BOX
The Multi-Weld Distribution Box (K1736-1) is avail-
able for interconnection of the Multi-System using the
same "pig-tail" connection method provided with the
Multi-Weld 350 converter. Six cable strain-relief ports
are provided for connection of up to (12) cables for
distribution or "daisy-chain" inter-connection to other
boxes. Four "pig-tail" leads (see below) are included
with the Box.
"PIG-TAIL" LEADS AND CONNECTORS
Accessory "pig-tail" leads and Twist-Mate connectors
are available from Lincoln for extra connections to the
Muli-Weld 350 or the Distribution Box:
