Panel selects pulse behavior.
Fault route
WSE Pulse Mode Not Working Diagnostic
A WSE AC/DC TIG pulse-mode diagnostic route.
Quick Answer
If WSE pulse mode does not work, split the fault between panel pulse command, control-board pulse processing, feedback response and secondary-stage behavior in AC mode.
- Pulse missing in both AC and DC points toward panel/control-board command processing.
- Pulse abnormal only in AC mode can involve secondary inverter/driver behavior.
- Feedback faults can make pulse appear wrong even when the panel command exists.
WSE pulse-mode route
Pulse command must survive panel, control board, feedback and output stage.
Control board generates pulse command.
Current feedback must follow pulse command.
Power stage must reproduce pulse current.
In AC mode, secondary switching can distort pulse behavior.
Pulse evidence table
| Observed behavior | Likely layer | Next check |
|---|---|---|
| Pulse missing in all modes | Panel or control-board pulse command. | Check panel command and control board. |
| Pulse works in DC but not AC | Secondary inverter/driver interaction. | Check secondary stage. |
| Pulse unstable | Feedback or current response issue. | Check feedback before panel replacement. |
| Pulse setting changes display only | Output stage not following command. | Check driver/power output response. |
