Ambient Air Temperature: 25°C Maximum Conductor Temperature: 85°C The above table is from HD 516 S2:1997 Duty Cycle and Current Carrying Capacity The current carrying capacity of a welding cable depends on the length of the duty cycle. The duty cycle is the length of time during which a loaded current passes through the cable over an operation period of 5 minutes, expressed as a percentage of that period. For example, if the current is flowing for the whole 5 minutes the duty cycle is 100%, and if the current is flowing for 1 minute the duty cycle is 20%. As conductor temperature varies according to the time in use as well as current, ratings shown are given as a guide. The permissible loading of the cable for duty cycles other than those shown in the table can be calculated using the following formula: I = I100 x √100/F Where: I : is the maximum permissible loading current for the required duty cycle. I100 : is the maximum permissible loading current for a duty cycle of 100%. F : is the required duty cycle calculated as a percentage of the 5 minute operation period. Typical guidance values for different welding processes are as follows: Fully automatic welding 100% Semi-automatic welding 65 - 85% Manual Welding 30 - 60% Very infrequent or occasional welding 20%
