Abstract
The invention provides a high flow power cable for a welding system designed for effective cooling of the power cable while maintaining maneuverability of the cable. Provided is a power cable having two segments, the first segment being larger in diameter than the second segment. The first segment is generally coupled to the power source and the second segment is coupled to the welding torch. The first segment includes a thicker wire, which has less resistance and dissipates less heat while the second segment includes a thinner wire, allowing for easier handling. Additionally, cooling fluid is conducted through the first segment and the second segment, further cooling the cable.
