WIRE REEL CHANGING

At the end of a coil, remove the last of the old elec- trode coil from the conductor cable by either pulling it out at the nozzle end of the gun or by using the follow- ing procedure:

1)Cut the end of the electrode off at the gun end. Do not break it off by hand because this puts a slight bend in the wire making it difficult to pull it back through the nozzle.

2)Disconnect the gun cable from the gun connector on the LN-10 wire drive unit and lay the gun and cable out straight.

3)Using pliers to grip the wire, pull it out of the cable from the connector end.

4)After the electrode has been removed, reconnect the gun cable to the drive. Load a new reel of elec- trode per the instructions in “Wire Reel Loading” in this section.

LOSS OF VOLTAGE SENSE SHUTDOWN

If the actual displayed voltage, when the trigger is closed, drops below 8.0 volts for over 0.8 second it is assumed the voltage feed back sensing circuit to the LN-10 is opened or faulty, so Loss of Voltage Sense Shutdown occurs until the trigger is released.

This shutdown stops the motor, shuts off the gas flow and disables the power source output to prevent the LN-10 voltage control from driving the power source output too high due to loss of proper feedback sensing via #21 (WORK) and #67 (ELECTRODE) sensing leads.

WIRE FEED OVERLOAD PROTECTION

The LN-10 has solid-state overload protection of the wire drive motor. If the wire drive motor becomes overloaded for an extended period of time, the protec- tion circuitry turns off the power source, wire feed and gas solenoid, and then displays “H30” on the WFS display (with blank Voltage display). This indicates the wire drive motor is overloaded and will remain shut down for about 30 seconds before the unit will automatically reset. The “H30” display decrements every second until it reaches “H00”. At that time, the unit resets automatically and the previous displays will return indicating the unit is ready to operate again. Overloads can result from improper tip size, liner, drive rolls, or guide tubes, obstructions or bends in the gun cable, feeding wire that is larger than the rated capacity of the feeder or any other factors that would impede normal wire feeding. (See “Avoiding Wire Feeding Problems” in the MAINTENANCE section).

GROUNDING LEAD PROTECTOR

The frame of the LN-10 Control is grounded to the frame of the power source by a lead in the control cable. An overload protector prevents welding current from damaging this lead if the electrode circuit touch- es the wire feeder frame while the electrode is electri- cally hot.

If such a grounding lead fault occurs, the WFS display will show “GLP,” (with blank Voltage display) and the trigger circuit will be disabled. To reset the circuit, release the trigger, make sure that the electrode is not touching the wire feeder frame, and then either press any key on the keypad or close the trigger. When the GLP circuit is reset, the “GLP” display is removed and the wire feeder is returned to normal operating mode.
