The amperage rating of a cord is a function of the wire gauge number of current carrying conductors and length of the cord.
2 welding cable amp rating.
1 a conductor that is used to carry an unbalanced current from the other conductors is not.
Amps 100 150 200 250 300 350 400.
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.
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.
When a cord has three current carrying conductors there is a decrease in amperage.
The total circuit length includes both welding and grounds leads based on 4 volt drop 60 duty cycle.
From the chart the proper cable size to select would be 2 0 cable.
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.
For arc welding cable applications.
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.
In actually service the load factor may.
