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.

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″.

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.

Nozzle Detection

Nozzle detection for the TOUGH GUN 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 present, a signal is then sent back to the robot controller or PLC.
