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 15mtr., are involved, it may be necessary to use cables of larger cross section to ensure that the voltage drop is not excessive & welding currents are maintained at adequate levels.
