What does it mean if the temperature status light is flashing at a steady rate indefinitely on my Miller Spectrum 875 Welding System?
If the Temperature status light is flashing at a steady rate indefinitely, it means the power source temperature sensor(s) provided inaccurate feedback but have returned to normal. The unit power must be cycled off and back on again.
What does it mean if the power light flashes steadily for 15 seconds on my Miller Spectrum 875?
If the Power light flashes steadily for 15 seconds, it indicates that the input power was above 300 volts AC or below 156 volts AC but has returned to normal.
Why does the arc go out while cutting with my Miller Welding System?
The arc may go out while cutting due to several reasons: * Ensure the work clamp is securely attached to a clean, paint-free, rust-free workpiece. * Make sure the drag shield is on the workpiece or the extended tip is 1/8 in. (3.2 mm) from workpiece while cutting. * If working with thin metal, maintain a constant travel speed. * Verify that the compressed air is clean, dry, and oil-free, using filter kit 300491 or 228926 if necessary. * Check the retaining cup, ensuring it is hand-tightened only and not over-tightened. * Clean or replace worn consumables.
What to do if the arc goes on and off while cutting with a Miller Spectrum 875?
If the arc goes on and off during cutting, consider the following: * Increase your torch travel speed, as it may be too slow. * Ensure the work clamp is securely attached to a clean, paint-free, rust-free workpiece. * Clean or replace any worn consumables.
