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 |

PRODUCT UPDATE — CHANGE TO THE CABLE USED ON TOUGH GUN® CA3 MIG GUNS
PRODUCT UPDATE — CHANGE TO THE CABLE USED ON TOUGH GUN® CA3 MIG GUNS
Effective January 1, 2025, as part of our ongoing commitment to focus on opportunities to innovate our product portfolio and continue delivering sustainable value to our customers, we will be making a change to the unicable used on our TOUGH GUN® CA3 robotic air-cooled MIG guns.
The new unicable provides better flexibility in cobot and conventional over-the-arm robotic welding applications.
It is important to note the amperage rating of the TOUGH GUN® CA3 MIG gun will change from 385-amp to 350-amp with mixed gases at 100% duty cycle (ratings are based on tests that comply with IEC 60974-7 standards).
There will be no change to configured TOUGH GUN® CA3 MIG gun part numbers or its replacement or service parts.
If you have any questions about this initiative, please contact your ITW sales representative.
NEW PRODUCT: SHROUDS FOR THE TOUGH GUN® TT4 REAMER AND WIRE CUTTER
NEW PRODUCT: SHROUDS FOR THE TOUGH GUN® TT4 REAMER AND WIRE CUTTER
We are pleased to announce the launch of our new reamer shroud and wire cutter shroud. These new shrouds are intended to encourage safe practices when the TOUGH GUN® TT4 reamers are used in cobot welding applications where the operator could be near the reamer during operation.
Moving forward, all TOUGH GUN® TT4A and TT4E reamers configured specifically for use in cobot welding applications will come factory-equipped with a reamer shroud, and if the reamer is configured with the wire cutter option, the wire cutter shroud will also be factory installed.
The wire cutter can be purchased with or without the wire cutter shroud, and the reamer and the wire cutter shrouds are both available for purchase separately for customers who would like to retrofit their existing equipment, but it is important to note that if retrofitting a reamer and/or a wire cutter manufactured before March 2024, additional components will be required.
Please contact our technical support team or your local ITW representative for additional assistance if trying to retrofit older models.

PRODUCT IMPROVEMENT – Change to Profile of TOUGH GUN® TA3 MIG Gun Connector Housings
PRODUCT IMPROVEMENT – Change to Profile of TOUGH GUN® TA3 MIG Gun Connector Housings
As part of our ongoing commitment to continuous improvement, we are making a change to the
TOUGH GUN® TA3 gun connector housing to accommodate an additional setscrew (see ‘Setscrew 2’
in Figure 2) which is designed to improve TCP repeatability when using long/extended length necks by providing additional support to help secure the neck firmly in place.
In order to make this change, extra thread engagement was required for the front setscrew which increased the profile of the front housing by 0.157” at the largest section (see Figure 3). And rather than the M6 x 1.0 setscrew currently used in our existing design, the new design uses two (2) M10 x 1.25 setscrews which have been tested and consistently achieved 340 in.-lbs. without causing any thread failures.
It is important to note that, like in our existing design, ‘Setscrew 1’ (see Figure 2) is responsible for the electrical (and mechanical) connection and must be installed and tightened properly, whereas ‘Setscrew 2’ is intended solely to achieve additional mechanical support. The sticker on the new gun connector housings has been revised to indicate a Step 1 / Step 2 approach (see Figure 4) to reflect this order of importance.
This incremental improvement will be rolled out as a running change as we work through current inventory, with full implementation targeted to be complete by the end of 2024.
If you have further questions or would like more information, please contact your local ITW representative.

PRODUCT UPDATE — CONFIGURATOR SIMPLIFICATION: S-GUN™ SEMI-AUTOMATIC MIG GUN CHANGES
Effective August 2024, we will simplify the configurable options of our S-Gun™ Semi-Automatic Air-Cooled MIG guns. The simplification plan includes the following:
- Cable options: Only available for 300 and 400 amps in lengths of 15 ft., 20 ft. and 25 ft.
- Handle options: Configurable with either T-Series handle (standard, locking triggers) or O-Series (standard trigger).

- Power Pins: Offered with Miller®, Tweco® 4 (with Miller® lead), Euro or Lincoln® power pins.
The S-Gun™ options will be removed from the BTB Semi-Automatic Air-Cooled MIG guns online configurator. We will create a dedicated product page for S-Guns™ on our website, which will also include a separate spec sheet.
In November, we will introduce an online configurator for S-Guns™.
The options removed from the configurator will remain available for purchase until the end of 2024. After this period, these options will be re-evaluated for potential discontinuation.
These changes aim to provide a more efficient and user-friendly experience for customers.
