Overheating prevention and duty cycle
The duty cycle ratings help you to know how to operate a Powermax® system without overheating it.
Duty cycle is the percentage of time during a 10-minute interval that a plasma arc can stay on without causing the plasma power supply to overheat.
| Output current | Duty cycle 1 |
|---|---|
| 45 A | 50% |
| 41 A | 60% |
| 32 A | 100% |
1 If the
ambient operating temperature is 40°C
(104°F). | |
If the plasma power supply
overheats:
- The plasma arc stops.
- The cooling fan inside the plasma power supply continues to operate.
- The temperature fault icon illuminates.
When the plasma power supply overheats, you must:
- Keep the plasma power supply on so that the fan can decrease the temperature of the plasma power supply.
- Wait for the temperature fault icon to go off before you start to cut again.
