SECTION 3 INSTALLATION

BEFORE MAKING ANY CONNECTIONS TO THE POWER SOURCE OUT

PUT TERMINALS MAKE SURE THAT ALL PRIMARY INPUT POWER TO

THE MACHINE IS OFF.

D. Output Welding Connections (Secondary)

The output connections are located on the front panel (Figure 2-4). The positive connection is located at the bottom left

corner and the negative connection is located at the bottom right corner. Table 3-2 provides the recommended second-

ary cable output sizes.

1. Connections From The Wire Feeder

The secondary output cable connects (in most cases) between the positive output lug of the MultiPower 460 Pulse and the

power connection block of the wire feeder. See the wire feeder installation instructions for other connections such as shield

gas, water, remote controls, Mig guns and wire feeder operation.

2. Connections For Stick And Tig Welding

The Tig torch and stick electrode holder connect directly to the appropriate MultiPower 460 Pulse output lugs on the lower

front panel. The choice of the Positive or Negative terminal depends on the welding process and electrode type being

used. In most cases the Tig torch will connect to the negative lug and work cable will connect to the positive lug. The stick

electrode holder usually connects to the positive lug and the work cable to the negative lug.

Table 3-2. Output Cable Sizes (Secondary)

* Total cable length includes work and electrode cables. Cable size is based on direct current, insulated copper conductors, 100-per-

cent duty cycle and a voltage drop of 4 or less volts. The welding cable insulator must have a voltage rating that is high enough to

withstand the open circuit voltage of the power source.
