Discrete control enables flexibility to monitor all motions and insert recovery or fault control, including a try again function after the first fault, and stop after the second fault. This new robotic nozzle cleaning station also has the ability to provide error diagnostics such as real time onsite troubleshooting without having to remove the unit from the cell.

Enjoy greater control optimization, remote monitoring capability, and faster troubleshooting of all discrete TOUGH GUN reamer I/O functions to facilitate increased productivity in your robotic welding applications.

Reduced Integration Time (compared to analog models)

  • Eliminates the need for an analog switch
  • Reduces cabling requirements in the robotic cell by up to 2 sets depending on number of additional peripherals
  • Fewer components = fewer potential points of failure

Remote Monitoring Capability

  • Error diagnostic and recording capability to minimize troubleshooting time
  • Enables remote monitoring and troubleshooting of the I/O of each reamer function and their allowable parameters through the PLC

Greater Control Optimization

  • Discrete control enables flexibility to monitor and adjust all motions for increased productivity in your specific welding application
    • In automatic mode, gain control over double-stroke, start-up dwell time, and top of stroke dwell time
    • In manual mode, gain control over the sequence and duration of each function by firing individual I/O (for advanced / challenging applications)

Safe and Accurate Setup

  • External setup switches allow independent operation of the sprayer, clamp and spindle during manual setup
  • Cutter blade lifts into position but does not spin when activated by the spindle setup swtich
  • Manual override switches are momentary for increased safety during setup / troubleshooting
  • Air blast and wire cutter are integrated through the Ethernet block, reducing setup time and maintenance of these options

Scalability and Flexibility

  • Use the TOUGH GUN TT3E Reamer as a switch to link robots with a single Ethernet port to an Ethernet welder or other peripheral devices for increased flexibilty
  • The base unit (configured with no options) has 6 configurable I/O, which allows monitoring or control of additional devices in the robotic cell

Ease of Maintenance

  • All wiring connections are built into the new wiring harness, reducing the risk of wiring errors during maintenance
  • Improved wire labeling for easy identification


  • 3/4 Horsepower lubricated air motor with gear reducer provides the high torque required for spatter removal at the lower speed needed to protect the spindle and cutter blade from excessive wear
  • No damage will occur to the air motor if stalling occurs
  • Operates in any position


  • Spindle has rotating rod accuracy of 0.001″ – 0.004″ at its extended position for cutting repeatability and optimized spatter removal
  • Fixed motor, clamp and v-block provide cutting accuracy and repeatability – No manual adjustments to nozzle clamps, cutter height, or motor height are required


  • All pneumatic valves are internally mounted
  • External setup switches are protected and seals protect points of entry


  • Rated voltage: 24 VDC
  • Operating voltage: ±10% of rated voltage
  • Power consumption: max. wattage in operation 5.3 W
  • Air requirements: 80 to 100 psi (5.0 to 7.0 bar) at 16 CFM (7.5 L/s)
  • Air motor (at min. air requirement): stall torque at 80 psi (5.5 bar) = 83 in.-lbs. (9.4 Nm)
  • Anti-spatter requirements: use only water-based anti-spatter liquid
  • Weight: ≅ 50 lbs (23 kg)*
  • Product dimensions (L x W x H): 13.5″ x 11.25″ x 21.0″ (343 mm x 286 mm x 534 mm)*

Optional Features


*The optional features are sold separately or added as options when ordering. These features can change the weight and physical dimensions of the product.

Lubricator shown from front


This dedicated motor lubricator maximizes performance and protects your TOUGH GUN reamer investment by extending the life of the motor, and is highly recommended for use in damp and moisture rich environments. Factory set for optimal pneumatic oil lubrication, the lubricator is available as an option when configuring your new unit* or is retrofittable to your existing TOUGH GUN TT3E reamer.

*Ordering your new TOUGH GUN reamer with the factory-installed lubricator option increases your warranty from 1 to 2 years, or increase your warranty to 3 years with the factory-installed lubricator option plus exclusive use of TOUGH GARD® anti-spatter liquid.

Filter/regulator shown from front on slight angle

Filter / Regulator

The Filter / Regulator unit from Tregaskiss is another recommended accessory that helps extend the life of your TOUGH GUN 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.

Tregaskiss TOUGH GUN spray containment unit

Spray Containment

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. Click here to learn more.

TOUGH GUN wire cutter

TOUGH GUN Wire Cutter

The TOUGH GUN 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″. Click here for more information.

Nozzle detect shown installed on TOUGH GUN TT3E reamer

Nozzle Detection

Nozzle detection for the TOUGH GUN TT3E 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 present, a signal is then sent back to the robot controller or PLC. Learn more about the nozzle detection system.
