WebJul 23, 2024 · When the current flows within range of its maximum capacity through cable then Normal current carrying capacity depends on three-factor-1- Heat dissipating properties of the cable. 2- Minimum conductor operating temperature. 3- Condition of installation means how the cable is laid underground or in the air. WebIt is essential to keep in mind (1) ampacity ratings decrease as length increases due to additional resistance, and (2) welding cable should be spread apart to allow heat to dissipate during use. GAUGE SIZE: It is critical to select the proper gauge size for the given welding application. A longer, thinner welding cable will carry lower ampacity.
