Ultra high performance flexible welding lead, double insulated for longer life and added safety

Current Rating :
The maximum current ratings of flexible welding cables for different duly cycles are based on an ambient air temperature of 25 C and a maximum conductor temperature of 90 C. The percentage duly 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.
