4.1 Machining Capacities

Mild Steel
Cast iron

4.2 Machine Environment

1. Do not position the machine where it receives direct sunlight.
2. Normal ambient temperature should be between +5°C (41°F) and 40°C (104°F).
3. Humidity: Between 30% and 95%. At maximum temperature of 40°C/104°F, relative humidity should
not be over 50%. Higher humidity is acceptable at relative lower temperatures (e.g. 90% humidity at
20C°).
4. Keep machine away from gasoline, chemical substances, dust, acid, sulfides, magnetic interference
and explosive environments.
5. Keep machine away from electrical interference sources such as welding machines and EDM
(Electric Discharge Machining).
6. Illumination of work area should be greater than 500lux.
7. Work area must have adequate ventilation.

4.3 Power Supply Requirements

1. Acceptable voltage fluctuation: normally +/- 10%
2. Acceptable frequency fluctuation: +/- 1Hz (50/60Hz)
3. Acceptable momentary power-off duration: less than 10m.sec
4. Acceptable voltage impulse:
Peak value: 200% or less than the line voltage of the actual value (rms.value).
Duration: 1.5m.sec or less.
5. Acceptable AC voltage of the waveform distortion.
6. Acceptable imbalance of the line voltage: 5% or less.
