The welding cable size chart below includes the wire gauge length of the wire diameter weight technical details and color of available.
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 amperage rating of a cord is a function of the wire gauge number of current carrying conductors and length of the cord.
Awg sizes will have three numbers for example 2 awg 625 30 this means that the welding cable has a total cross sectional area of 2 awg and is made from 625 strands of 30 awg wire.
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.
For arc welding cable applications length in feet for total circuit for secondary.
View the awg reference table below for dimensions and sizing of welding cable.
Welding cable size is measured by the american wire gauge awg standard.
4 0 the total circuit length includes both welding and grounds leads based on 4 volt drop 60 duty cycle.

The higher the gauge number the smaller the.
Usually a general purpose house circuit is designed for 20.
Besides the cross sectional area other factors that impact the ampacity of welding cable are its length ohm rating i e resistance rating temperature ratings of the insulation.
You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating.
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.
Current is measured in amperes or amps.
The tables below are intended to be a general guide for wire size and amp ratings.
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.
