DISCONTINUED PRODUCT — BA1 COBOT MIG GUN

Effective January 1, 2025, all Tregaskiss® BA1 cobot air-cooled MIG guns will be discontinued and replaced with TOUGH GUN® CA3 robotic air-cooled MIG guns.

The change supports our commitment to maximize efficiencies and focus on delivering our best quality solutions to our customers.

Please contact your ITW sales representative with questions. 

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.

DISCONTINUED PRODUCT – Select Reamer Stand Heights

In effort to maximize efficiencies and continue to focus on delivering sustainable value to our customers, effective December 20, 2023, we will be discontinuing a variety of reamer stands due to low demand and sales volume.

TOUGH GUN® reamer stands are still part of our product portfolio and will remain available, in heights between 18 and 36 inches in 6-inch increments.

PRODUCT UPDATE – Washers to Be Pre-installed on All Tregaskiss® Cutter Blades

As part of our ongoing commitment to continuous improvement, beginning in February 2024 customers will begin to notice that Tregaskiss® cutter blades are coming with a pre-installed washer which is secured and held in place by an o-ring. This incremental improvement provides more convenience for customers by ensuring the washer remains securely in place and gets properly re-assembled when the cutter blade needs to be removed or replaced.

Effective February 5, 2024, this modification will be rolled out as a running change across our complete lineup of cutter blades. There will be no change to cutter blade part numbers, but please note that packaging will change to accommodate the addition of the washer.

PRODUCT IMPROVEMENT – BA1 Cobot MIG Guns to Feature Lighter Unicables

Effective February 20, 2024, as part of our ongoing commitment to continuous improvement, we are making a change to the unicable used on our Tregaskiss® BA1 cobot air-cooled MIG guns.

The new unicable better addresses customer needs for a lighter more flexible cable in their cobot welding applications. It is important to note the amperage rating of the BA1 cobot 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 BA1 gun part numbers, but BA1 replaceable unicables are changing and will have the following new part numbers:

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.

Packaging Change — Wire Cutter No Longer Packaged Separately When Configured on a TOUGH GUN® TT4 Reamer

October 23, 2023

In effort to consolidate and simplify packaging and shipments, please note that effective immediately, customers who order a TOUGH GUN TT4 reamer robotic nozzle cleaning station configured with a wire cutter will no longer receive their wire cutter in a separate package as part of their shipment. The wire cutter unit is now being included inside the same single box with the reamer.

Affected Part Numbers:

• All TOUGH GUN TT4 reamer part numbers ending in “WL” (i.e. TT4A093801WL)
• All TOUGH GUN TT4 reamer part numbers ending in “PL” (i.e. TT4E106001PL)
