SEC 09 // TROUBLESHOOT & CHECKS
Troubleshoot & checks
Fault, alarm and pre-use pages for welding PAPR systems, built from source-cited records. Each page tells you what the symptom means, the steps you can safely do yourself, and the point where you must stop and send the unit for authorised service. This is ownership information, not safety advice — it does not replace training or a workplace RPE assessment.
Pre-use checks
Identify your kit
3M Speedglas Adflo PAPR
- Adflo battery charge lasting less than expected
The battery pack's charge lasts a noticeably shorter time than you're used to, even though you're charging it as normal.
- Adflo low airflow alarm: what it means and what you can check
The audible alarm sounds and all three LEDs on the power switch light up while you're wearing the Adflo PAPR.
- Adflo low battery alarm: what it means and what you can check
The bottom bar of the battery indicator flashes and the audible battery alarm sounds while you're wearing the Adflo PAPR.
- Adflo: no airflow and no alarm — the fault with no warning
You notice no air is reaching the headtop, but neither the audible alarm nor any LED has triggered.
