| WELD CABLE SIZES |
|
Table A.1 has the copper cable sizes recommended for different currents and duty cycles. Lengths stipu- lated 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 mini- mizing voltage in the welding circuit.
