Welding Lead Gauge Chart. These values for current-carrying capacity are based on a copper temperature of 60C 140F an ambient temperature of 40C 104F and yield load factors from approximately 32 for the 2 AWG cable to approximately 23 for the 30 AWG. The larger the AWG number or wire guage the smaller the physical size of the wire.
Finally from 201-251 feet you will use a 1-gauge welding lead. Welding Cable Ampacities The total circuit length includes both welding and ground leads based on 4-volt drop 60 duty cycle Required Cable Sizes. From 101-150 feet you will use a 3-gauge welding lead and from 151-200 feet you should use a 2-gauge welding lead.
AWG is popular in the US.
This information is for reference only and it is highly recommended the user consult a licensed electrical engineer for a particular welding application. The British Standard Wire Gauge SWG is another gauge system that was used in the past but has been gradually displaced by the AWG. Whether youre a beginner or expert in the world of welding you need to know about the different sizes of welding cableWelding cable is the electric conductor that carries a current.
