What does it mean when the pressure status light is on for Miller Welding System?
If the Pressure status light is illuminated: * Check for sufficient gas/air supply pressure. * Inspect the air filter for dirt and replace if necessary. * Check air lines for leaks.
What does it mean when the cup status light is on for Miller Spectrum 875 Welding System?
If the Cup status light is on: * Check the torch shield cup. * Try resetting the power switch.
Why is the temperature status light on for my Miller Welding System?
If the Temperature status light is on, the unit may be overheating. Allow the fan to run until the light turns off, indicating the unit has cooled down.
What does it mean if the pressure status light flashes at a rate of two quick flashes and then a one second pause for a duration of 15 seconds on my Miller Spectrum 875 Welding System?
If the pressure status light flashes at a rate of two quick flashes followed by a one-second pause for 15 seconds, it indicates that the unit's regulated pressure is too high. Check for input pressure between 90-120 PSI and reset the power switch.
What does it mean if the cup status light flashes at a rate of three quick cycles and then a one second pause for 15 seconds on my Miller Welding System?
If the cup status light flashes at a rate of three quick cycles and then a one-second pause for 15 seconds, it means that the power source detected that the tip and electrode failed to separate when the gas valve turned on. Check that the cup is not too tight (finger tight only). Also, check for correct torch consumables and for gas flow through the torch head.
What does it mean if the temperature status light stays on indefinitely on my Miller Welding System?
If the Temperature status light remains on indefinitely, the power source temperature sensors may have failed, or the ambient temperature is below -22° F (-30° C). Try operating the unit in a warmer environment.
What does it mean if the pressure status light flashes steadily for 15 seconds on my Miller Spectrum 875 Welding System?
If the Pressure status light flashes steadily for 15 seconds, it indicates that the regulated pressure is too low. Check the torch for leaks and ensure the input pressure is between 90-120 PSI during cutting.
What does it mean if the cup status light flashes at a rate of two quick cycles and then a one second pause for 15 seconds on my Miller Welding System?
If the Cup status light flashes at a rate of two quick cycles followed by a one-second pause for 15 seconds, it indicates that no pilot arc was established, and the power source failed to maintain a pilot arc. Try a different set of torch consumables (tip and electrode), and check for input pressure between 90-120 PSI.
What does it mean when the power light flashes at a rate of two quick cycles and then a one second pause on my Miller Spectrum 875 Welding System?
If the Power light flashes at a rate of two quick cycles and then a one-second pause, it indicates that the input power is above 300 volts AC or below 156 volts AC. Also, pre-charge PTCs may be overheated; allow 15 minutes for the unit to cool.
What does it mean if the cup status light flashes steadily for 15 seconds on my Miller Spectrum 875 Welding System?
If the Cup status light flashes steadily for 15 seconds, the system failed to strike an arc, and the power source failed to deliver current to the output. Check the continuity of torch connections (pilot lead and electrode lead).
