Temperature LED faults
The temperature LED illuminates while the machine is powered ON.
 The system overheated. Leave the system on to allow the fan to cool the power supply.
 If the system’s internal temperature approaches -30°C (-22°F), the temperature LED may
illuminate. Move the system to a warmer location.
The temperature LED blinks while the machine is powered ON.
 Leave the system on to allow the fan to cool the power supply. The temperature LED blinks when
the system continuously draws too much input current for too long. Try the following to prevent this
condition:
 Turn down the cutting current. See Step 3 – Adjust the output current on page 43.
 Operate the system on a 240 VAC input circuit whenever possible.
 Avoid stretching the arc. Drag the torch on the workpiece. See Edge start on a
workpiece on page 50.
 Operate the system without using an extension cord. If you must use an extension
cord, use a heavy conductor cord of the shortest possible length. See Extension cord
recommendations on page 29.
 Make sure nothing else is drawing power on the same circuit.
