NOTE: This portion of the documentation covers the faults and setup parameters of the WT6000 Weld Control. This section of the manual is geared towards line builders, maintenance personnel and welding engineers to assist with procedures related to programming the weld control.
« 6: Programming Schedules | 8: Linear Current Steppers »
Below is a complete list of the Programmable Faults and Setup Parameters for the WT6000 weld control with timer software G08300. To view a detailed description, click on the name of the fault or setup parameter and the table will expand. Click on the name again to collapse the table.
Perform the following steps on the DEP-300s to edit either a Programmable Fault or Setup Parameter:
STEP |
DESCRIPTION |
01: |
Press Program Mode (F2). |
02: |
Press Review Setups (F4). |
03: |
Press the UP or DOWN arrow keys to move the cursor to the fault or parameter line to be edited. |
04: |
Press ENTER. |
05: |
Press the UP or DOWN arrow keys to select a fault severity option or enter the required parameter value with the numeric keys. |
06: |
Press ENTER. |
07: |
Press APPLY (F2). [Saves changes to the DEP-300s only.] |
08: |
Press DOWNLOAD (F2). [Downloads the changes to the weld timer. When complete, a "Download Complete" message wil appear.] |
The user can set the severity of the programmable faults. The severity option tells the weld processor how to respond when a fault condition is detected. Conversely, the severity of non-programmable faults are fixed and cannot be changed. See Non-Programmable (Hidden) Faults below.
SEVERITY OPTIONS |
SEVERITY DESCRIPTION |
---|---|
FAULT |
When a fault condition is detected by the weld processor, the Fault bit will go HIGH and the No Fault bit will go LOW. Fault conditions generally (with a few exceptions) inhibit the initiation of a weld schedule. |
ALERT |
When an alert condition is detected by the weld processor, the Alert bit will go HIGH and the No Alert bit will go LOW. Alert conditions generally do not inhibit the initiation of a weld schedule. |
NONE |
When a fault condition is detected, the weld processor still logs the fault, but inhibits the Fault or Alert bits from turning on (HIGH). This condition will not inhibit the initiation of a weld schedule. |
Faults can be reset by either pressing the Reset (F5) button in the Fault Status Menu in the DEP-300s or turning the Fault Reset input bit HIGH. Perform the following steps to reset faults via the DEP-300s:

The following is a list of the non-programmable faults in the WT6000. Their default values are fixed and cannot be changed. Since these faults are non-programmable, they are hidden from view in the DEP-300s View Setups Menu. For more information regarding these faults, see Ch. 10: Fault Diagnostics.
