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-percent 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.

Before making any connections to the
power source output terminals make
sure that all primary input power to the
machine is off.
INSTALLATION
D. OUTPUT WELDING CONNECTIONS
(SECONDARY)
The output connections are located on the front panel (Figure 2-5). 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
secondary cable output sizes.
1. CONNECTIONS FROM THE WIRE FEEDER
The wire feeder control cable connects to the 19 pin J1 receptacle on
the lower front left of the MultiPower 460 Pulse. 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 connec-
tions 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.
Check the voltage links for proper volt-
age on the Input Terminal board before
applying primary power.
