The Tregaskiss® TT4E reamer is a robotic nozzle cleaning station with Ethernet communication that powers through weld spatter to improve gas flow, reduce porosity, and keep your robotic cell running.
The Tregaskiss® TT4E reamer powers through weld spatter to improve gas flow and reduce porosity, rework, and scrap in robotic welding. A 0.95 HP motor delivers 236 lbs. of spindle lifting force, and durable components keep it running: the lubricated motor lasts up to 18 million cycles, valves and cylinders are rated for 10 million+, and the optional wire cutter runs 1 million+ cycles without maintenance. Ethernet communication integrates the reamer into your facility’s digital controls, with daisy-chain wiring, a customizable ream cycle, and a double-stroke function. A 20-oz reservoir with low fluid level indicator, dedicated motor lubricator, and spray containment unit come standard to reduce downtime and cell clean-up. A fixed motor, clamp, and v-block mean no manual adjustments, and labeled wiring and external setup switches make setup and service easy. Backed by a 2-year warranty, extended to 3 years with exclusive use of TOUGH GARD® anti-spatter liquid.

Ideal for use in cobot welding applications, the new reamer shroud encourages safety where the operator could be near the reamer during operation. All new reamers configured specifically for use in cobot welding applications come standard with a factory-installed reamer shroud.
Our TT4 reamers can be retrofitted with the reamer shroud, but if converting a reamer that was manufactured prior to March 2024, additional components will be required. Contact our Technical Services team for additional assistance if required.

The Tregaskiss wire cutter removes the ball-end of the welding wire to provide smooth arc starts and consistent wire stick-out. The TOUGH GUN wire cutter easily cuts a variety of wire types from stainless steel to aluminum to flux-core in wire sizes up to 1/16″.

The new wire cutter shroud is ideal for use in cobot welding applications where the operator could be near the wire cutter during operation. The Tregaskiss wire cutter is available with or without a wire cutter shroud, but when configuring a new reamer with the wire cutter option specifically for cobot welding applications, the wire cutter shroud comes factory installed.

The innovative spray containment unit from Tregaskiss helps prevent air contamination by catching anti-spatter overspray in its sealed basin, improving the air quality of the working environment and maintaining the cleanliness of the weld cell.

The Filter / Regulator unit from Tregaskiss is another recommended accessory that helps extend the life of your Tregaskiss reamer. The filter cleans the air supply to the reamer and restricts debris from reaching the motor, keeping it uncontaminated and ensuring maximum performance and longer life, while the regulator works to ensure optimal air pressure is achieved at the unit.

Nozzle detection for the Tregaskiss TT4E reamer uses a proximity sensor mounted on the side of the reamer that can be used independently of the ream cycle. The robot positions the front end of the MIG gun close to the sensor to detect the presence of the nozzle. If the nozzle is not present, a signal is then sent back to the robot controller or PLC.

Tregaskiss is pleased to announce improvements to the design of our cutter blades. These new cutter blades are engineered from harder, stronger material for enhanced performance and durability, making them more resistant against breaking, snapping, chipping or cracking.

Compatible with Tregaskiss® and most competitive consumables, these four-sided v-blocks ensure your cutter is concentric with your consumables and your nozzle bore to guarantee the most effective ream. Choose from five available v-block options when configuring your new TOUGH GUN TT4E reamer.

Tregaskiss provides a simple fixed height durable stand for all Tregaskiss TT4A and TT4E reamer models.
Tregaskiss Reamer stands are available in heights between 18 and 36 inches in 6-inch increments.

TOUGH GARD anti-spatter liquid was developed to address the performance requirements of metal fabricators. TOUGH GARD anti-spatter liquid won’t harm machinery or clog the sprayer like oil-based anti-spatter solutions, it cleans up easily with no residue, it’s safe to use and it’s safe for the environment. Helping prevent spatter adhesion and extending the life of consumables, TOUGH GARD anti-spatter liquid reduces downtime thus lowering operating and maintenance costs.

The TOUGH GARD multi-feed system for anti-spatter solution can connect up to ten Tregaskiss TT4 reamer stations. This system eliminates the need to refill anti-spatter reservoirs on a frequent basis, resulting in lower operating costs, reduced downtime and increased safety.
