LN-742 Connection Instructions

Turn the Invertec® power switch "off"

A K1819-1 Input cable assembly is required to con- nect the LN-742 to the Invertec®.

Connect the control cable from the LN-742 to the 14-pin MS-style connector.

Connect the electrode cable to the output terminal of the polarity required by electrode. Connect the work lead to the other terminal.

Set the meter polarity switch on the front of the Invertec® to coincide with wire feeder polarity used. The wire feeder will now display the welding volt- age.

If a remote control such as K857 is to be used with the LN-742, the remote can be connected directly to the 6-pin MS-style connector on the front of the Invertec® or use a K864 adapter to connect the LN-742 and the remote to the 14-pin MS-style connector.

Cobramatic Connection Instructions

Turn the Invertec® power switch "off"

Connect the control cable from the Cobramatic to the 14-pin MS-style connector.

Connect the electrode cable to the output terminal of the polarity required by electrode. Connect the work lead to the other terminal.

Set the meter polarity switch on the front of the Invertec® to coincide with wire feeder polarity used.

If a remote control such as K857 is to be used with the Cobramatic, the remote can be connected directly to the 6-pin MS-style connector on the front of the Invertec® or use a K864 adapter to connect the cobramatic and the remote to the 14-pin MS- style connector.

TIG Module K930-2

The TIG Module connects to the Factory and Advanced Process V450-Pro versions with a K936-1 (9-14 pin) control cable. Connect the K936-1 to the 14-Pin MS- style connector.

General Instructions for Connection of Wire Feeders to V450-Pro

Wire feeders other than those listed above may be used provided that the auxiliary power supply rating of the V450-Pro is not exceeded and the V450-PRO out- put is not actively controlled by the wire feeder. (Like an LN-9). K867 universal adapter plug is required. See connection diagram S24985 in Operator Manual.

REMOTE CONTROL OF INVERTEC®

Remote Control K857, Hand Amptrol K963 and Foot Amptrol K870 may be used.

PARALLEL OPERATION

The V450-Pro are operable in parallel in CC mode. For best results, the currents of each machine should be reasonably equally balanced. As an example, with two machines set up in parallel for a 800 amps procedure, each machine should be set to deliver approximately 400 amps, not 450 amps from one and 350 amps from the other. This will minimize nuisance shutdown condi- tions. In general, more than two machines in parallel will not be effective due to the voltage requirements of procedures in that power range.

To set machine outputs, start with output control pots and arc control pots in identical positions. Use the out- put control pots to balance the currents and maintain the desired current. The arc control pots should be kept identical on the two machines.
