To install: (See figure #31)
1. Turn the input power off at the welding power source.
2. Connect one end of the center lead to the power source electrode connection, and the other end to the wire feeder
electrode connection.
3. Connect the outer lead bundle to the power source work connection, and the other end to the work piece. Minimize
the length of any work lead extension for best results.
4. Insulate
all
connections

Weld Cables, Standard
Table 2 has copper cable sizes recommended for different currents and duty cycles. Lengths stipulated are the distance
from the welder to work and back to the welder again. Cable sizes are increased for greater lengths primarily for the
purpose of minimizing cable drop

Negative Electrode Polarity
The Power Feed 84 ships from the factory configured for
electrode positive polarity. See P.81 in the Operations
Section (Set-Up menu) to select negative polarity
welding.
