NBR INSULATED EXTRA FLEXIBLE COPPER
WELDING CABLE
This extra flexible welding cable comes with premium NBR insulation and high-conductivity copper strands for efficient current delivery during welding operations. Engineered for flexibility and toughness, it withstands repetitive flexing and harsh environments while ensuring long service life. Suitable for secondary connections to electrodes and use in automatic or handheld welders across various industrial setups.
generally conforms to, Based on CENELEC HD 22-6 31, VDE 0282, IEC 245-6, BS 6899, IS 6830/84
Elongation = 300 Min.
- Designed for the secondary (high current) connection to automatic or hand – held metal arc welding electrodes. It is suitable for flexible use under rugged conditions, on assembly lines and conveyor systems, in machine tool and automatically operated line and spot welding machines.
- Coils 100, 200, 300 and 500 m. in wooden reels
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%
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.
