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 conduct or temperature of 90 C. The percentage duly cycles
for various processes and applications are as follows:
- Automobile Welding : up t o 100%
- Semi Automatic Welding : 30% t o 85%
- Manual Welding : 0% t o 60%
- Very intermittent or Occasional Welding : upto 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.
