Update to Liner Descriptions
Update to Liner Descriptions
As part of our on-going simplification efforts, we are renaming our current selection of MIG gun liners. This change is effective now, as you will see our literature and website content being updated to reflect the simplified naming structure.
We offer four different liner types between our semi-automatic and automation MIG guns. The chart below will show the previous liner name/reference as well as the updated liner name/reference.
It’s important to note that the liners themselves are not changing. We will continue to deliver the same premium quality liners, using the same part numbers as we currently do.
| Previous Liner Name/Reference | Updated Liner Name/Reference |
|---|---|
| AccuLock S (Dual Lock) Liner | Front Load Liner |
| Conventional Liner | Rear Load Liner |
| QUICK LOAD® Pro Liner (Automation Only) | E-Z Feed™ Liner |
| QUICK LOAD® | (There is no name change for this product) |

PRODUCT CHANGE — AccuLock™ S Conventional Liner Gas Diffusers — O-Ring Color Change to Gray
All AccuLock S conventional liner gas diffusers began shipping with a gray o-ring instead of a black o-ring on February 22, 2023. The gray o-ring makes it easier to tell the difference between an AccuLock S dual-locked liner gas diffuser and an AccuLock S conventional liner gas diffuser.

PRODUCT UPDATE – AccuLock™ S Power Pin Cap Design Change
PRODUCT UPDATE — AccuLock™ S Power Pin Cap Design Change
The design of all AccuLock S power pin caps will be updated to allow retention of AccuLock S liners with a set screw instead of a rubber washer. This running change impacts Bernard® BTB MIG guns. It takes place on March 17, 2022.
All BTB MIG guns configured with AccuLock S consumables ordered and/or built after March 17, 2022 will include the new set screw. The same can be said for orders placed for replacement AccuLock S power pin caps.
Additional changes include:
- Each size of AccuLock S power pin cap will have a visible gas sealing washer that is color matched to compatible liner shrink tube
- Wire size compatibility will change for two AccuLock S liners:
| Liner Part Number | Former Wire Size Compatibility | New Wire Size Compatibility |
|---|---|---|
| LA6A-XX | 5/64″ (2.0 mm) – 3/32″ (2.4 mm) | 5/64″ (2.0 mm) |
| LA7A-XX | 3/32″ (2.4 mm) – 7/64″ (2.8 mm) | 3/32″ (2.4 mm) |
- A new Euro power pin option (a two-piece assembly comprised of power pin and pass-through gun connector) will be offered when configuring Bernard BTB MIG guns with AccuLock S Consumables.
New design advantages include easier power pin cap installation, improved liner retention and simpler identification of compatible parts.
Additional considerations:
- No change to how Bernard BTB MIG guns configured with AccuLock S consumables are ordered
- T-handle hex wrench included with every Bernard BTB MIG gun configured with AccuLock S consumables
- Extra set screw included with every Acculock S liner, can also be ordered separately
- No change to the way Miller® MDX™ gun liners are retained at this time

The AccuLock S consumables system is designed to address liner trim length errors and erratic wire feeding. The AccuLock S liner is locked and concentrically aligned to both the contact tip and the power pin without the use of fasteners, which provides a flawless wire-feed path that guarantees smooth, uninterrupted delivery of the wire to the weld puddle. Plus, the liner replacement process has been error-proofed so you can trim your liner accurately and easily every time, with no measuring.
Important Note:
The AccuLock S consumables system requires all AccuLock components: contact tip, diffuser, nozzle, liner, neck insulator, power pin and power pin cap.
Reduce troubleshooting, production downtime and rework with AccuLock S Consumables.
