Bug-O Systems has introduced two new accessories for the Modular Drive System (MDS): automated height control and seam tracking.

The automated height control system provides automatic up/down positioning of the torch when using CV weld processes. Features include current set point control and manual or automatic mode.

The seam tracking system uses an electromechanical probe mounted ahead of the welding torch to follow the weld joint and provides automatic, motorized left/right adjustment of the welding torch position. Control modes are automatic or manual.

Air filtration unit

RoboVent’s eDrive air filtration system uses a sensor to monitor the airflow through the unit. Then using a variable-frequency drive, it automatically adjusts the motor’s RPM to compensate for filter loading.

According to the company, energy peaks and valleys are evened out, 20 to 30 percent of energy is saved, and filter life is extended by as much as 30 percent.
