WELD CONNECTIONS
•
Turn the machine OFF before connecting/disconnecting
welding equipment.
•
Loose connections will cause the output terminals to
overheat. The terminals may eventually melt.
•
Do not allow bare weld cable to touch the machine or
front doors
FIGURE A.3

Positive (+) weld terminal
2.Negative (-) weld terminal
For most stick, gouging, MIG and gas shielded flux cored welding
procedures, connect the wire feeder or spool gun to the Positive
(+) terminal and the work lead to the Negative terminal.
For most self-shielded flux cored and TIG procedures, connect the
electrode holder or wire feeder to the Negative (-) terminal and the
work lead to the Positive (+) terminal.
WELD CABLES, STANDARD
Tabulated below are 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.
TABLE A.1
** Tabled values are for operation at ambient temperatures of 40°C and
below. Applications above 40°C may require cables larger than recom-
mended, or cables rated higher than 75°C
