Discontinued Products – AutoLength™ Power Pins
To continue to provide the best products and solutions to our customers, we routinely review, assess and evaluate our product line-up to ensure their features and benefits still hold their value. Accordingly, we have decided to discontinue our AutoLength™ power pins, effective January 10, 2025.
These AutoLength pins are currently used across both semi-automatic and robotic/fixed automatic product lines. Until the effective date, you can still purchase existing configurations as well as replacement AutoLength pins (or until inventory is depleted, whichever occurs first).

PRODUCT CHANGE — AccuLock™ Conventional Liner Gas Diffusers
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.
For reference, the AccuLock gas diffuser part numbers listed below will be assembled with a gray o-ring:
| Part Number | Description |
| D-A1-C | AccuLock S Gas Diffuser, Large Nozzle, Thread-On, Conventional Liner |
| D-A2-C | AccuLock S Gas Diffuser, Large Nozzle, Slip-On, Conventional Liner |
| DS-A1-C | AccuLock S Gas Diffuser, Small Nozzle, Thread-On, Conventional Liner |

PRODUCT CHANGE — TOUGH LOCK™ Retaining Head O-Ring Color Change
PRODUCT CHANGE — TOUGH LOCK™ Retaining Head O-Ring Color Change

The o-ring used in select TOUGH LOCK retaining heads has changed. The functionality and design will remain the same, the only noticeable change is a slight variation in the color, transitioning to a darker shade of green.
All orders shipped after June 27, 2022 will be assembled with the new o-ring.
The following retaining heads are affected by the change:
| Part Number | Description |
|---|---|
| 404-30 | TOUGH LOCK retaining head for robotic applications; heavy duty, single taper, qty: 100 |

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.
PRODUCT CHANGE — Changes to Crimping on Select Nozzles
PRODUCT CHANGE — Changes to Crimping on Select Nozzles
August 4, 2020
Effective immediately, you may notice a slight change to the crimp area of some Tregaskiss® nozzles. Within our manufacturing process, we have begun to transition from six-jaw to eight-jaw crimpers. Rest assured that the durability and performance of Tregaskiss nozzles will remain the same.
The only difference you will notice is a slight change limited to the crimp area of the nozzle. The difference is shown below:
Timeline for Transitioning to Eight-Jaw Crimpers
(Actual ship dates will be dependent upon existing inventory levels at time of assembly transition)
- July 2020: This transition has already begun on part number 401-6-62, with additional part numbers to follow
- August 2020: All heavy duty (HD) Tregaskiss nozzles will transition to the new style crimp and will be completed by August 31
- September 2020: All standard duty (SD) Tregaskiss nozzles will transition to the new style crimp and will be completed by September 30

Tregaskiss Nozzles for AccuLock R Consumables
April 3, 2020
Tregaskiss is proud to announce the addition of two new nozzles to the AccuLock™ R consumables offering. Only slightly larger than 1/2″ bore nozzles, these 5/8″ bore nozzles offer almost the same weld access while still providing the clearance needed for reliable gas flow and reaming to the gas holes.
Part Numbers
- 401-30-62 – 5/8″ bore, 1/8″ stick out, brass, slip-on, 0.938″ O.D.
- 401-30-62T – 5/8″ bore, 1/8″ stick out, brass, thread-on, 0.938″ O.D.
These new nozzles are also now configurable on TOUGH GUN® TA3 and CA3 robotic air-cooled MIG guns. Learn more about AccuLock R consumables, or configure your robotic MIG gun online.
February 14, 2020 Tregaskiss® and Bernard® branded nozzles are currently packaged in a variety of bag sizes and styles. We will begin standardizing on a single size and style bag for all Tregaskiss and Bernard nozzles over the coming months as a running change that takes place as existing inventory is depleted. 5″ x 8″ (white) 8″ x 10″ (white) 6″ x 8″ (clear) 8″ x 10″ (white) (subject to change depending on volume changes)
October 23, 2019 Tregaskiss is pleased to announce the launch of new AccuLock™ R consumables, a system designed to maximize throughput and efficiency with minimal risk and effort. AccuLock contact tips last longer and are virtually impossible to cross-thread. The long contact tip tail concentrically aligns the tip within the diffuser prior to thread engagement, and this coupled with the tip’s coarse thread ensures quick, accurate replacement without cross-threading. An upgrade to AccuLock HDP contact tips can extend life by 10x or more in pulse welding applications. You can easily switch from TOUGH LOCK® and other consumables to AccuLock R consumables with no impact to tool center point (TCP), making this upgrade low effort, low risk, and high payoff. Plus, Tregaskiss AccuLock R consumables and Bernard® AccuLock S consumables share a common contact tip, so you can benefit from the reduced costs and simplified inventory of a common consumable platform™ if you have a combination of robotic and semi-automatic MIG guns in your facility. Reduce troubleshooting, downtime and rework with these new consumables. Learn more about Tregaskiss® AccuLock™ R consumables.
