Nozzle Cleaning Stations TOUGH GUN TT4A and TT4E Reamers


Nozzle Cleaning Stations TOUGH GUN TT4A (analog) and TT4E (ethernet) Reamers maximize uptime and weld quality in robotic welding operations. These stations provide superior cleaning performance to power through spatter, improving gas flow and reducing porosity.


Both reamers offer a powerful .95HP motor and 236 lb (107 kg) 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.


An anti-spatter reservoir 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.


The reamers both feature a four-sided v-block that eliminates the need to purchase new v-blocks when changing nozzle styles.


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