3M Speedglas 9100XXi Parts and Cover Lens Guide
The 3M Speedglas 9100XXi is the top-tier auto-darkening filter in the 9100 series, adding Natural Color Technology and TIG ratings as low as 1 amp to an already strong lineup. Keeping it performing means knowing the right consumable and replacement part numbers - and understanding that many 9100 parts are shared across the series while others are cartridge-specific. This guide maps out the parts ecosystem clearly.
The ADF Filter: The 9100XXi Cartridge
The 9100XXi is the auto-darkening filter (ADF) cartridge - not just the helmet shell. The cartridge is designated 06-0000-30i. This is important because the 9100 series uses different filter cartridges at each performance level:
| Cartridge | Part Number |
|---|---|
| 9100V | 06-0000-10 |
| 9100X | 06-0000-20 |
| 9100XX | 06-0000-30 |
| 9100XXi | 06-0000-30i |
If you need to replace the entire ADF cartridge (due to cartridge failure, LCD damage, or an upgrade from 9100XX to 9100XXi), order 06-0000-30i. This cartridge is available directly from 3M and authorized Speedglas distributors.
Battery for the 9100XXi
The 9100XXi ADF uses a coin-cell battery for the electronics. The Speedglas 9100 series uses the 04-0320-00 battery (sold in pairs/case). This is a 3M-branded CR2450 equivalent - not the same part number as Lincoln or Miller batteries, but the same CR2450 chemistry.
The 9100 series requires two batteries per ADF cartridge. The battery holder is located within the headband assembly - on the 9100 series, the batteries are accessed through the headband, not the ADF cartridge itself. The battery holder part number is available through 3M’s parts catalog.
Signs the battery needs replacement are the same as any ADF: inconsistent or failed arc detection, slow darkening response, or the ADF not responding to arc exposure.
Cover Lenses: Understanding 9100 Series Inside Lens Variants
The 9100XXi uses a larger inside protection plate than the 9100V and 9100X. This is where ordering errors most commonly occur.
Outside protection plate (outer cover lens) - 06-0200-51 This is the standard outside protection plate shared across the entire 9100 series (9100V, 9100X, 9100XX, 9100XXi) and also the G5 series. Sold in packs of 10 (standard) or 50 (bulk). A scratch-resistant variant is 06-0200-52 and a high-temperature variant is 06-0200-53.
Inside protection plate (inner cover lens) - by variant:
| Variant | Inside Plate Part Number |
|---|---|
| 9100V | 06-0200-10 |
| 9100X | 06-0200-20 |
| 9100XX / 9100XXi | 06-0200-30 |
The 9100XXi uses the same inside plate as the 9100XX (06-0200-30), sold in packs of 5. This is larger than the 9100V and 9100X inside plates. Do not substitute.
Shell and Front Panel
Silver front panel - 06-0300-55 (or 06-0300-55-B for a 5-pack) The front panel is the cosmetic and protective outer shell face of the 9100 helmet. If the shell gets cracked or heavily spatter-damaged, this part can be replaced independently from the ADF cartridge and headgear.
The 9100XXi-specific silver front panel may also be listed as part 532100 at some retailers (Rapid Welding lists this as the “Silver Front Cover 9100XXi”). Verify with your retailer which variant fits your specific helmet configuration.
Shell with side windows - 06-0300-52SW For 9100 helmets with side window cutouts. The side windows accept shade 5 side filter lenses, providing peripheral vision to the sides during welding. Separately purchased side filters install in the shell side openings.
Headgear and Headband
Standard headband - 06-0400-51 (full assembly, also sold in 5-packs as 06-0400-51-B) The primary headband assembly for 9100 series helmets. Includes the adjustment mechanism and crown support.
Pivot mechanism headband - 06-0400-52 The pivot mechanism component of the headband assembly.
Sweatband - 06-0200-54 (3-pack, also sold in 12-packs as 06-0200-54-B) The comfort sweatband. Same across most 9100 configurations. Replace when worn or saturated from extended use.
Hard Hat Adapter
Hard hat adapter - 06-0014-00NR Mounts the 9100 series helmet onto a standard hard hat. Available from 3M directly (3M stock number 7100291855) and authorized distributors.
Adflo System Compatibility
The 9100XXi is commonly paired with 3M’s Adflo PAPR unit for combined welding and respiratory protection. The Adflo system connects to the 9100 shell via a breathing tube. The Adflo unit has its own battery (Li-Ion, available in standard and heavy-duty configurations) and its own filter set. Those parts are separate from the helmet’s own ADF battery and cover lenses.
For Adflo-paired configurations, the system is sold as the “9100 FX-Air” variant and uses the same 9100 ADF parts described above plus Adflo-specific accessories.
FR Ear and Neck Protectors
For welders doing overhead or positional work where spatter falls behind the helmet, FR ear and neck protectors that attach to the 9100 shell are available from Weld-Ready and other distributors. These are supplemental accessories, not numbered in the standard 3M parts poster.
