Miller Electric 714D manual Auxiliary Menu, Run-In, Burnback, Min And V-Max, Arc Time, Cycles

Auxiliary Menu

•An auxiliary menu is provided if both the Se- quence and Setup push buttons are pressed simultaneously. The Setup push button LED flashes when the auxiliary menu is displayed.

.The auxiliary menu may be exited at any time by pressing both the Sequence push button and the Setup push buttons simul- taneously.

Run-In

•The Setup push button is used to step through menu selections. The Manual over- ride run-in wire speed selection is indicated by the upper display of “RUNI”, and the low- er display indicates the run-in wire speed setting of the active program. The Adjust control is used to set the desired run-in wire speed.

The lower display shows “AUTO” to indicate that automatic run-in is active. The Adjust con- trol can be used to change the setting from “AUTO” to a run-in wire speed setting (50–780). The active program is displayed in the Program display. The active program can be changed by pressing the Program push button, then selecting the desired program with the Adjust control.

Run-in settings are program specific. For ex- ample, program 1 can be set at 50 IPM run-in, and program 2 can remain on the Automatic setting. When the unit is set for Automatic, run-in wire speed is set automatically to one￿ half weld sequence wire speed.

Burnback

•If the Setup push button is pressed, the unit allows burnback time to be set.

Burnback time and voltage can be specified when the lower display indicates “BURN” and the upper display indicates the burnback time or voltage. The Adjust control is used to set the desired burnback time or voltage. Burnback

settings, like run-in settings, are program spe- cific. The active program is displayed in the Program display and can be adjusted (see Section 5-4).

V-Min And V-Max

•If the Setup push button is pressed, the unit allows the setting of the manual override power source min and max voltage preset range. The minimum voltage is displayed in the upper display and the lower display indi- cates “VMIN”. When the Setup push button is pressed the unit displays the maximum voltage setting of the welding power source. The maximum voltage is displayed in the upper display and the lower display indi- cates “VMAX”.

In both cases, the Adjust control is used to specify the minimum and maximum voltage settings of the welding power source. The set- tings correspond to arc voltage obtained at minimum command and arc voltage obtained at maximum command.

Arc Time

•If the Setup push button is pressed, the unit displays arc time in hours.

Arc time is indicated by the Program display showing “HR”. Arc time is shown in the lower display.

Cycles

•If the Setup push button is pressed, the unit displays the number of cycles.

Arc cycles are indicated by the Program dis- play showing “CL”. The arc cycle count is shown in the lower display.

Trigger Hold Setup

•If the Setup push button is pressed, the unit allows trigger hold delay time to be set.

Trigger hold delay time is indicated by ”HOLD” in the lower display and the hold delay time in the upper display. The adjust control can be used to specify a new delay time for trigger

hold. Trigger hold delay time is the minimum amount of time the trigger must be held for trig- ger hold to work when the trigger is released (the trigger hold function must be on). For ex- ample, if a trigger hold delay time of 2.0 sec- onds is defined, the operator must hold the trigger for at least 2 seconds before releasing it in order for the trigger hold function to work. Once the trigger hold function is in effect, the wire feeder will stay On until the trigger is pressed and released again.

•There is an additional function built in called ”maximum trigger hold time” which is the maximum length of time the trigger can be held and the trigger hold function still work when the trigger is released (the trigger hold function must be on). The maximum trigger hold time is set at 4.0 seconds after the trig- ger hold delay time. For example, if a trigger hold delay time of 2.0 seconds is defined, and the operator held the trigger in for more than 6.0 seconds, the trigger hold function would not be in effect and the wire feeder would stop when the trigger is released.

•When the Setup push button is pressed again, the menu repeats to the first menu selection of run-in wire speed selection.

Reset To Factory Settings

A reset menu is displayed if the following four push buttons are pressed simultaneously: Program, Sequence, upper display, and Set- up. The upper display indicates “WIPE” and the lower display prompts the operator with the word “ON” or “OFF”. The lower push but- ton is active indicating that the Adjust control can be used to change the unit to “WIPE ON”. When “WIPE ON” is set, if the original four push buttons are simultaneously pressed a second time, the unit will reset all settings to factory default except the arc time and arc cycle counts. If a reset is not desired, set the display to “WIPE OFF” and simultaneously press the Program, Sequence, upper display, and Setup push buttons to exit the reset menu.
