Welding Cable Gauge Chart. Gauge or gage sizes larger than one are zero also expressed as 10 pronounced one aught two zeros expressed as 20 pronounced two aught 30 and 40. End-users select the welding power supplys rated output duty cycle and the circuit length to determine the correct cable size.
Table 1 is an example of a welding cable sizing chart. 18 gauge 050 x. For cables larger than 40 sometimes kcmil will be used instead of 50 60 etc.
