OUTPUT CONNECTIONS

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 maximum rated current at 100% duty cycle a minimum size of 4/0 AWG welding cable 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 out- put 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.

MULTI-SOURCE OUTPUT LIMITATIONS

The number of Multi-Weld Converters that may be con- nected to a single Multi-Source Power Source is deter- mined by the following formula:

Power Source (Volts x Amps) capacity > 1.1 x Sum

of Converters’ (Volts x Amps) arcs

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 available 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 distrib- ution or “daisy-chain” inter-connection to other boxes. Four “pig-tail” leads (see below) are included with the Box.

PARALLELING

Machines may be paralleled for increased output. The S20428 paralleling kit permits paralleling of two MULTI- SOURCE power supplies for supplying currents of up to 1000 amps, 100% duty cycle.

“PIG TAIL” LEADS AND CONNEC- TIONS

Accessory “pig tail” leads and Twist-Mate connectors are available from Lincoln for extra connections to the Multi-Weld 350 or the Distribution Box:
