2 awg welding cable ampacity.

Factors tor ambient temperature and number of conductors have been applied. Awg metric cable size comparison now when selecting the proper cable size for your welding equipment it is best to choose cable that can handle the maximum output of the welder. Or 15 amperes for 12 awg and 25 amoeres for 10 awg aluminum after any correction. The total circuit length includes both welding and grounds leads based on 4 volt drop 60 duty cycle.

104f 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. The sizes of cables generally used ranged from 2 awg to 3 0 awg. Figure 2 shows a comparison between welding cables in awg sizes and metric sizes. Current is measured in amperes or amps.

You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. Usually a general purpose house circuit is designed for 20. For 14 awg 20 amperes for 12 awg and 30 amperes for 10 awg copper. Ampacity also known as current carrying capacity or current rating is the maximum amount of current that a cable can safely carry without exceeding its operating temperature rating due to the heat generated from losses and ambient heat around the cable welding cable ampacity is a common source of confusion because it is calculated differently than other types of wire and therefore appears to.

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 the 3 0 awg.
