11. APPLIED FUNCTION (continued)
13) E-820 Display
If “E-“ and “820” blink in the displays, it indicates the “Motor overcurrent warning”.
Contact resistance to the feeding parts causes motor current to increase. If the motor current
exceeds 70% of the rated duty cycle, “E-“ and “820” in the displays will blink only while no
operation at the front panel is carried out. When pressing any key or starting welding again, “E”
and “820” in the displays will disappear (, but welding power source does not stop automatically).
In this case, check for short circuit in the motor power
transmission line, rough feeding of wire, and an error in the torch or the wire feeder. Refer to
Section 10.2.1(10) “Setting of Feed Motor Load Current Error Detection Level”.
14) E-830 Display
If “E-“ and “830” in the displays blink, it indicates the “Motor overcurrent”.
If short circuit in the power line to the motor or motor overload happens, “E-“ and “830” in the
displays will blink and the welding machine will automatically stop. In this case, check for short
circuit in the power supply line, rough feeding of the wire, and an error in the torch or the wire
feeder.
15) E-900 Display
If “E-“ and “900” in the displays blink, it indicated the “Microcomputer error”.
There could be an error in the built-in microcomputer, Please contact your dealer immediately.
When contacting your dealer, you are required to provide the details of the problem you are
facing.
