Technical Data Table
Current Rating : The maximum current ratings of flexible welding cables for different duty cycles are based on an ambient air temperature
of 25°C and a maximum conductor temperature of 90°C. The percentage duty cycles for various processes and applications are as follows :
» Automobile Welding : up to 100%
» Semi-automatic Welding : 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 many be necessary to use cables of larger cross section to ensure that the voltage drop is not excessive and welding currents are maintained at adequate levels.
Application
NBR / NBR
Designed for the secondary (high current) connection to
automatic or hand – held metal arc welding electrodes. It
is suitable for flexible use under rugged conditions, on
assembly lines and conveyor systems, in machine tool and
automatically operated line and spot welding machines.
