2 welding cable amp rating.

The total circuit length includes both welding and grounds leads based on 4 volt drop 60 duty cycle. For arc welding cable applications. The amperage rating of a cord is a function of the wire gauge number of current carrying conductors and length of the cord. The important specs to go by when choosing the appropriate wire that is suitable for your applications are the wire gauge amp voltage rating and the length needed.

The sizes of cables generally used ranged from 2 awg to 3 0 awg. In actually service the load factor may. As an example let s assume you have a 400 amp power source at 60 duty cycle and need a total combined length of electrode plus work cables of 100 feet. When a cord has three current carrying conductors there is a decrease in amperage.

Other charts are available from cable manufacturers and welding reference books. Description these values for current carrying capacity are based on a copper temperature of 60 c 140 f an ambient temperature of 40 c 104 f and yield load factors from approximately 32 for the 2 awg cable to approximately 23 for. And yield load factor of approximately 32 from the 2 awg cable approximately 23 for the 3 0 awg cable and higher for the smaller sizes. From the chart the proper cable size to select would be 2 0 cable.
