New TOUGH GUN® TT4A and TT4E Reamers Power Through Spatter to Increase Uptime and Weld Quality

WINDSOR, Ontario. (September 14, 2021) — Tregaskiss has introduced its new TOUGH GUN TT4A (analog) and TT4E (ethernet) reamers to maximize uptime and weld quality in robotic welding operations. These nozzle cleaning stations provide superior cleaning performance to power through spatter, improving gas flow and reducing porosity so more time can be spent welding.

Both reamers offer a powerful .95HP motor and 236 pounds of lifting force at 95 psi. Engineered from harder, stronger material, the cutter blades are more resistant to breaking, chipping or cracking.

Adding to the reamers’ performance are several features designed to keep robotic welding operations running for extended periods of time. These include durable valves and cylinders rated for 10M+ cycles and a wire cutter that can run 1M+ cycles without requiring maintenance. The reamers also feature a powerful motor that lasts up to 18M cycles at 80+ psi. A standard motor lubricator supports that performance by extending the life of the motor; it is highly recommended for use in damp and moisture rich environments.

New standard anti-spatter features

Tregaskiss has integrated several new standard features into the TOUGH GUN TT4A and TT4E reamers to help reduce downtime, safety incidents and costly weld defects associated with the use of anti-spatter liquid. 

An anti-spatter reservoir with 20-ounce capacity reduces the need for frequent refills to improve productivity, while a low fluid level indicator sends an alert to the PLC/robot when anti-spatter solution is low. This minimizes the risk of running out and helps prevent poor weld quality from lack of shielding gas due to spatter build up. The reservoir includes a tethered cap and easy-clean filter to protect against anti-spatter contamination, which can also lead to weld quality issues. It mounts directly to the reamer frame to increase durability. The reservoir is compatible with the TOUGH GARD® anti-spatter multi-feed system to provide a continuous supply of anti-spatter solution to up to 10 reamers from a 5-gallon pail or 55-gallon drum.

Also standard is a spray containment unit that captures anti-spatter overspray in an enclosed basin, lessening the potential for slip and trip accidents, improving air quality and reducing downtime and cost for cleanup. The weld cell remains dry and clean.  

Versatile features and additional options

The TOUGH GUN TT4A and TT4E reamers both feature a four-sided v-block that eliminates the need to purchase new v-blocks when changing nozzle styles, while the TT4E model with ethernet provides greater control and flexibility for remote operation. 

Both reamers have external setup switches that allow independent operation of the sprayer, clamp and spindle during manual setup. 

Tregaskiss offers additional options for the reamers to further enhance their versatility, including a wire cutter that removes the ball at the end of the welding wire for smoother starts and consistent stickout, along with a reamer stand. A nozzle detect sensor confirms the presence or absence of a nozzle prior to welding to support consistent weld quality and reduce rework. An optional filter/regulator extends motor life by cleaning the air supply to the reamer and keeping debris from entering the motor.

New Tregaskiss BA1 Air-Cooled Cobot MIG Gun Increases Uptime and Throughput

New Tregaskiss BA1 Air-Cooled Cobot MIG Gun Increases Uptime and Throughput

WINDSOR, Ontario. (March 31, 2021) — Tregaskiss has incorporated its well-known and dependable performance into the new BA1 cobot air-cooled MIG gun. The gun’s simple and durable design helps operators stay focused on welding, not troubleshooting, to help increase uptime and throughput. The BA1 cobot MIG gun also uses long-lasting AccuLock™ R consumables — a combination that minimizes downtime, improves weld quality and further drives productivity. 

Users can depend on the BA1 cobot MIG gun for its durability in manufacturing environments. The gun features metal-to-metal keyed connections that hold it in place in the mounting arm and keep the strong, aluminum-armored neck firmly in place in the gun body. The BA1 cobot MIG gun has a user-friendly, easy-to-grip mounting arm and free-drive options to simplify and speed programming. It offers 385 amps of power at a 100% duty cycle using mixed gases. 

Simplified installation

Tregaskiss delivers the BA1 cobot MIG gun fully assembled, including AccuLock consumables. This, along with minimal fasteners and a precision-machined keyway mounting system, makes installation of the gun and mounting arm quick, easy and accurate. Adding to the ease of installation, Tregaskiss has made power pins available for an assortment of wire feeders and offers insulating discs that are designed to match various brands of cobots.  

Less frequent, easier maintenance 

The BA1 cobot MIG gun uses QUICK LOAD® liners that maintenance personnel or welders can replace from the front of the gun without disturbing it, the wire or the feeder connection, for faster changeover. AccuLock contact tips are also fast and easy to install. 

High quality and versatility

AccuLock contact tips prevent the cross-threading that can lead to weld-quality problems. The tip’s long tail concentrically aligns within the diffuser before coarse threads engage, making the contact tips virtually impossible to cross-thread.

The consumables are part of a Common Consumables Platform™ and are also compatible with Bernard® semi-automatic MIG guns and Tregaskiss fixed automatic and robotic MIG guns. The platform minimizes inventory and simplifies its management, so more time is spent on welding.
