What to do if my Lincoln Electric Welding Accessories unit will not sense current?
If your Lincoln Electric Welding Accessories unit isn't sensing current, it might be due to welding current being too low. Try looping the cable two or three times on the current sensor. Alternatively, the current sensor or PC board may be damaged, requiring replacement.
How to fix a Lincoln Electric Miniflex Welding Accessories motor that does not start?
If the motor of your Lincoln Electric Welding Accessories unit does not start, verify that 115 VAC/60Hz, 1ph (K2376-1, K3972-1) or 230 VAC/60Hz, 1ph (K3973-1) input power is available at the machine. Also, check if the circuit breaker has tripped and reset it if necessary. Finally, inspect the carbon brushes and replace them if they are worn.
Why does my Lincoln Electric Miniflex unit cycle between low and high speeds?
If your Lincoln Electric Welding Accessories unit automatically cycles between low and high speeds, start by checking the connections from the PC board to the motors to ensure they are secure. If the connections are not the problem, the control panel or PC board might be damaged and need replacement.
What to do if my Lincoln Electric Miniflex motor stops automatically?
If the motor of your Lincoln Electric Welding Accessories unit stops automatically, it's possible that thermal protection has been activated. Make sure that the cooling underneath the top cover and/or the outlet are not obstructed.
