Questions and answers
Miller plazma 875 sikakliq ışığının yanması sonrunu
The indicator lights on the Miller Electric Spectrum 875 Auto-Line plasma cutter provide status information:
- Power light flashing at two quick cycles with a one-second pause: Input power is above 300V AC or below 156V AC. A qualified technician should check the input power.
- Pre-charge PTCs overheated: Allow 15 minutes for the unit to cool.
- Pressure status light flashing at two quick flashes with a one-second pause for 15 seconds: Unit-regulated pressure is too high. Check input pressure (90-120 PSI). If the issue persists, a Factory Authorized Service Agent should inspect the unit. Reset the power switch.
- Pressure status light flashing steadily for 15 seconds or until the torch trigger is pressed: Regulated pressure is too low. Check for leaks in the torch and ensure input pressure is between 90-120 PSI during cutting.
These lights help diagnose power and pressure issues in the plasma cutter.
