PRODUCT UPDATE — New Motor Lubricator Enhancements for TOUGH GUN® TT4A and TT4E Reamer Robotic Nozzle Cleaning Station
Improvements have been made to the dedicated motor lubricator on Tregaskiss® TOUGH GUN TT4A and TT4E reamers. Effective immediately, all new TOUGH GUN TT4 reamer orders will come equipped with the new lubricator, without any impact to the reamer part number. However, it is important to note that if ordering the lubricator separately, the part number has changed from TT4-LUB to TT4-2250.
New TT4-2250 motor lubricator enhancements:
- Better drip rate control provides more accurate and consistent oil feed rate into the motor
- No need to remove parts to check the oil level! Easily identify the oil level through a sight glass located on the outside of the lubricator
- Air fittings are metal which better protects them from spatter
Same mounting footprint, no special adaptors needed.
If you have any questions regarding this change, please contact your local ITW sales representative.

PRODUCT UPDATE – CHANGES TO THE TREGASKISS® 600 AMP ROBOTIC WATER-COOLED MIG GUN OFFERING
September 20, 2023
In order to ensure focus on opportunities to innovate our product portfolio and continue delivering sustainable value to our customers, the changes identified below will be made to the Tregaskiss® 600 amp robotic water-cooled MIG gun offering effective September 29, 2023.
Physical changes to the product:
The gun housing of 600 amp robotic water-cooled MIG guns not equipped with wire brake will feature a wire brake plug (part number RW16-WBP). This change will also allow customers to install wire brake at a later date with the appropriate wire brake kit without having to change the gun housing.
There will be no change to MIG guns equipped with wire brake.
Changes to configurable options:
Additionally, due to low demand, please note that all 45-degree neck and 0.035” (0.9 mm) wire size options will be removed from the 600 amp robotic water-cooled MIG gun configurator.
If you have questions or need assistance with regard to these changes, please contact your local ITW welding sales representative.

PRODUCT UPDATE – Tregaskiss TOUGH GUN® TT4 Reamer Robotic Nozzle Cleaning Station Online Configurator and Reverse Lookup Tools
Tregaskiss introduces a new online configurator for its TOUGH GUN® TT4 reamer robotic nozzle cleaning stations. The new mobile-friendly configurator allows users to quickly and easily customize their analog or ethernet reamer for their exact application. Users simply follow a series of steps to configure a reamer model, first selecting the V-block and cutter blade to match the outside diameter (OD) and bore of their robotic MIG gun nozzle. Users can then select from various add-ons, including a wire cutter or nozzle detect. Tregaskiss also offers the option to choose accessories sold separately, such as a reamer stand, anti-spatter liquid and an anti-spatter multi-feed system.
After choosing all desired components, the configurator provides a summary of the selections, along with a part number for the reamer. Users can access downloadable replacement parts lists, exploded view diagrams and other valuable takeaways that they can print, save in PDF format for later, or share via email.
Along with the online configurator, a new reverse part number lookup function for Tregaskiss TOUGH GUN® TT4 reamer robotic nozzle cleaning stations is available. By entering a fully configured TOUGH GUN TT4 reamer part number, users get access to a downloadable detailed replacement parts list and other relevant resources specific to their configuration.

Product Improvement – LSR+ (Plus) Unicables
PRODUCT IMPROVEMENT –
LSR+ Unicables with SmoothTurn™ Technology
October 11, 2022
For use with TOUGH GUN® TA3 ThruArm® series robotic MIG guns, LSR+ (Low-Stress Robotic) unicables incorporate new SmoothTurn™ technology to maximize production uptime.
Conventional style unicables typically come with a connection that limits rotational capabilities and produces torsional stress in the cable. Unlike conventional unicables, the LSR+ incorporates a rotating power connection that reduces this stress during rotation. Additionally, a protective external conduit contributes to cable longevity by shielding components from harsh welding environments.

Stress Relieving Features
- SmoothTurn Technology reduces frictional forces on internal components increasing overall cable life up to 300%
- Enhanced electrical connections provide a more stable arc, resulting in less spatter and longer cable life
- Unique internal components improve support and bend radius of the cable during heavy robot articulation

NEW PRODUCT — TOUGH GUN® TT4A and TT4E Nozzle Cleaning Stations
We are pleased to announce the launch of the new TOUGH GUN® TT4A and TT4E reamer nozzle cleaning stations. Tregaskiss has enhanced the trusted dependability of our existing TOUGH GUN TT3 and TT3E reamers with superior performance, high durability components and new standard features. With increased uptime and weld quality, you’ll spend less time maintaining and troubleshooting your robotic welding equipment and more time getting product out the door.

These new reamers power through the toughest spatter with a .95HP motor and 236 lbs. of spindle lifting force at 95 psi. Their higher durability components help to keep your welding operation up and running for extended periods of time:
- Powerful, lubricated motor lasts up to 18M cycles at 80+ psi
- Durable valves and cylinders rated for 10M+ cycles
- Wire cutter can run 1M+ cycles without requiring maintenance
Now included as standard are new features that help reduce downtime, safety incidents and costly weld defects related to anti-spatter:
- A new anti-spatter reservoir with increased fluid capacity;
- A new low fluid level indicator that sends a signal to the PLC / robot when anti-spatter is running low; and
- A new spray containment unit that reduces risk of slip / trip hazards due to overspray contamination.
Discontinuation of TOUGH GUN® TT3 / TT3E Reamers
Tregaskiss will discontinue the sales of the TT3 and TT3E reamers beginning 09/01/2021. However, we will continue to offer TT3 / TT3E replacement parts for a period of five years (until 2026).
