Safety Requirements
-
Bending radius : approx 15 x Cable Dia.
-
Coiled welding cable must always be spread out before use to avoid overheating in use.
-
Cables must not be spliced within 10 feet of the holder.
-
Welding cable must never be coiled or looped around the body of the worker
-
Cables with damaged insulation must be replaced.
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 meters., are involved, it may be necessary to use cables of the larger cross-section to ensure that the Voltage drop is not excessive and welding currents are maintained at adequate levels
When total cable lengths in excess of 15 meters., are involved, it may be necessary to use cables of the larger cross-section to ensure that the Voltage drop is not excessive and welding currents are maintained at adequate levels
