For best wire feeding performance, place the LN- 25™ PRO on a stable and dry surface. Keep the wire feeder in a vertical position. Do not operate the wire feeder on an angled surface of more than 15 degrees.

Table A.1 Located below are copper cable sizes rec- ommended for various 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 voltage drop in the cables.
