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 may 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.
