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).
The charts below show the standard power pin that replaces each AutoLength option for both welding applications. You may also find instructions here for replacing an AutoLength power pin with a standard power pin.
To configure a new MIG gun part number using a standard power pin, please utilize our online configurators. Your new configuration will also include a full parts list.
If you have any questions or need assistance configuring a new gun or finding a replacement part number, please contact our Customer Service Team by phone at 1.855.MIGWELD (1.855.644.9353) or via email at CS@itwmig.com.

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.

Key MIG Gun Components for Job Performance
Key MIG Gun Components for Job Performance
MIG welding is a common welding process especially useful for beginner and DIY welders due to its easy-to-learn nature, shorter lead times and lower production costs. The versatility of MIG welding allows users to work on a wide range of materials with less stopping and restarting. The process features a continuous consumable wire electrode being fed through a welding gun and into a weld pool. The gun also feeds a shielding gas alongside the wire to protect the weld pool from contaminants.
While there are different types of MIG guns that have unique parts (e.g., water-cooled, air-cooled, fume extraction), all MIG guns have some parts in common. Understanding the components of a MIG gun and the process by which it works will help you make decisions on the consumables and gun type you select for your job. Here’s what you need to know.
CONSUMABLES
1. Nozzle
- The nozzle directs the shielding gas to cover the weld puddle.
- By shielding the weld puddle, the nozzle helps to prevent spatter on the weld surface while simultaneously protecting internal components of the gun from heat and spatter.
2. Contact Tip
- The contact tip guides the wire and transfers the current from the neck through the filler metal and to the work surface. Consistent wire feeding ensures a stable arc and high weld quality.
3. Diffuser
- The diffuser conducts electricity to the contact tip while dispersing gas evenly across the weld pool.
- Ensuring even distribution of shielding gas ensures consistent coverage of the weld pool, preventing contamination and defects like porosity and oxidation.
4. Liner
- The liner is crucial to MIG welding because it guides the wire electrode from the wire feeder through the cable to the contact tip.
- A worn or low-quality liner can cause friction, leading to inconsistent feeding and arc instability and, ultimately, poor weld quality.
- There are several materials of liners for consideration, each with advantages in different applications.
ESSENTIAL GUN COMPONENTS
5. Neck
- The neck is the front-end extension of a MIG welding torch and houses vital components like the contact tip, gas nozzle and wire feeder inlet.
- It directs the welding arc and shielding gas precisely onto the weld joint, improving weld quality and consistency.
- Selecting the right neck (i.e., long versus short) is important because it impacts a welder’s posture, visibility and heat control.
6. Handle and Trigger
- The handle and trigger impacts how long an operator can weld without experiencing fatigue.
- Handles with an ergonomic design and a natural feeling grip will improve operator comfort and welding duration.
- When selecting a trigger, it needs to be responsive to the touch and best suited for the job (e.g., multi-schedule, locking).
7. Cable Assembly
- In MIG welding, the cable assembly delivers power, gas, filler metal and control signals to the welding gun.
- Without the successful transmission of each of these elements, the weld will not function as intended.
- Compression fittings are an integral aspect of the assembly because they provide a reliable connection, better energy transfer and less resistance.
OTHER COMPONENTS
8. Insulator
- Plays a critical role in electrical isolation and heat management.
- Made of a non-conductive material to help electrically isolate the metal components of the welding gun (e.g., the trigger mechanism) from the electrical circuit carrying the welding current.
- Acts as a thermal barrier between nozzle and trigger mechanism, preventing overheating and malfunctions.
9. Power Pin
- Power pins provide a direct connection for wire, weld power and gas flow between the welding machine and/or wire feeder and the MIG gun. An accurate gun-to-machine connection is critical to ensure that the filler wire, gas and weld power are passed efficiently to the gun.

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.
