CURRENT RATING :
The maximum current ratings of flexible welding cables for different cycles are based on an ambient air temperature of 25C and a maximum conductor temperature of 90C. The percentage duly cycles for various processes and applications are asfollows :

Automobile Welding : up to 100%

Semi Automatic Welding : up 30% to 85%

Manual Welding : 0%to 60%

Very intermittent or Occasional Welding : up to 20%

VOLTAGE DROP:
When total cable lengths in excess of 15 mtrs. are involved, it may be necessary to use cablesof larger cross section to ensure that the voltage drop is not excessive and welding currents are maintained at adequate levels.
