| Note: |
Insulation thickness, Sheath thickness and overall dimensions are nominal values.
The number of wires is approximate and strand diameter is nominal; they shall be
such as to satisfy the requirements of conductor resistance as per IS 8130/1984, BS-6360, IEC-60228 & VDE-0295. |

Current Rating |
| |
The maximum current ratings of flexible welding cables for different duly cycles are based on an ambient
air temperature of 250C and a maximum conductor temperature of 900. The percentage duly cycles given
in the table are based on a cycle time of 5 minutes. The typical duly cycles for various welding processes
and applications are as follows |
| |
1 Automobile Welding : upto 100%
2 Semi-automatic welding : 30% to 85%
3 Manual Welding : 30% to 60%
4 Very intermittent or Occasional Welding : upto 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. |
