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:

Order No.
