Duty Cycle Performance (Approximate)
Welding cables are often rated based on their 'Duty Cycle.' For 16 sq mm copper cables, the current capacity varies:
- 100% Duty Cycle (Continuous): ~135 Amps
- 60% Duty Cycle: ~175 Amps
- 30% Duty Cycle: ~245 Amps
Note: Always ensure that the cable is marked with the ISI logo and the specific cross-sectional area (16 sq mm) for safety compliance on-site.
