10 Ground Current Detect Error Display

Weld current has been detected in the earth ground connection.

May be caused by a conductor making connection to the unit chassis.

11 Wire Stick Error Display

The welding wire has stuck to the workpiece at the end of the weld.

May be caused by improper range settings or improper data loaded into the interface unit.

3 No Volt Sensed Error Display

The arc voltage sense circuit did not receive feedback within the required time after an arc was established.

May be caused by an inability to establish an arc in the pulse schedule, or a lack of voltage feedback.

4 No Tach Sensed Error Display

The motor tachometer feedback is not reaching the control.

May be caused by obstructions in the wire

7 Stop Weld Cycle Error Display

An error has been detected and the robot hasn’t stopped the weld cycle, causing the interface unit to stop the weld cycle and wait for the robot to stop.

8 Error Card Read Display

The card reader is not working properly.

May be caused by a bad data card, a bad data card reader, a faulty microprocessor circuit board, or a wiring problem.

9 No Flow Detected

No coolant is detected after preflow in the weld cycle. Check coolant system and flow switch for proper operation.

May be caused by poor weld conditions.

12 Arc Fail Time Out Error Display

An arc was not established within the allotted time.

May be caused by an inoperable wire drive, absence of shield gas, or improperly operat- ing welding power source.

13 No Input IPM Display

Analog IPM (inches per minute) from robot is not being received.

May be caused by having no wire feed speed programmed at the robot.
