4.7.4 Alert Set-up

In addition to providing diagnostic information, the built-in current sensor can be used to trigger
low-current warnings to alert the operator that current may have been insu cient to form a weld. The
Alert Setup menu brings up two sub-menus, Alert Thresholds and Alert Indicators, which allow the
trigger levels and alert actions to be set independently. Note that alerts only apply to Double-Sided
mode. Single-Sided welding is heavily a ected by the surfaces being welded and the placement of the
ground electrode, making visual inspection more e ective than current monitoring in this mode.

4.7.4.1 Alert Thresholds

In this menu the user can set low-current warning levels for each of the 3 power levels. If the
weld current drops below the set threshold for a speci c power level, the welder will take the
action(s) speci ed in the Alert Indicators Menu.

4.7.4.2 Alert Indicators

If the welder detects a low current condition based on the thresholds mentioned above, it will
respond based on the following settings:
Show Feedback
This setting controls the display of weld results on the LCD. Pushing the weld control knob
multiple times will cycle through the following options:
1. OFF: Weld results are never shown after a weld, and alerts are disabled. Audible Alert and
Weld Cuto menu options will be hidden.
2. ERR: Results will only be shown if a low current condition is detected.
3. ALL: Results will be shown after all Double-Sided welds, regardless of measured current.
Audible Alert
When this option is set, an alarm will sound when a low current condition is detected.
Weld Cuto
When selected, this option will prevent further welds after a low current condition until the
operator presses the weld control knob, returning the unit to the Home screen. The Ready LED
will also ash amber during this time. If this option is disabled and the Show Feedback option is
set to ERR or ALL, the weld results will be displayed during the cooldown period, reverting
automatically to the Home screen when the Ready LED is lit.
