The CB-WCS/15 is a control box that is used in central extraction systems with extraction arms, to connect max. 15 automatic start/stop devices WCS to the mains. It is used as an interface between a welding cable sensor, an automatic damper, a frequency inverter and a central fan.

The output of the automatic start/stop device WCS are being converted into an output signal which lays between 4-20mA, to arrange the extraction volume of the central fan by means of a frequency inverter. It is also possible to set the fan’s run-out period (per individual extraction arm) and initial delay (for the entire system).

Plymovent Control Equipment FAQs

Straight answers to the questions people ask most about controls for welding fume extraction systems.

What does fume extraction control equipment actually do?

Control equipment switches extraction fans and dampers on and off, and can adjust the airflow to match what is happening in the workshop. Instead of a fan running at full power all day, it runs only when and where extraction is needed.

This cuts wasted energy, reduces noise and wear, and keeps heated air in the building rather than blowing it outside. It ranges from simple manual switches to fully automatic systems.

What is the difference between manual and automatic control?

Manual controls rely on someone switching the system on and off, perhaps with a switch at each workstation. They are simple to understand, but extraction is often left running when it is not needed.

Automatic controls respond to the work: for example, they start extraction when an arm is moved or welding begins, and shut it down afterwards. They suit larger systems with many workstations. Check the manual for your own equipment to see which control methods it supports.

What does a frequency inverter or variable speed drive do?

It adjusts the speed of the fan motor, so the fan gives just the airflow the system needs. When fewer extraction points are in use, the fan slows down and uses less power.

A drive can also start the motor gradually, which is gentler on it than starting at full speed. It must be correctly sized and set up for the motor, and wired by a competent electrician. Check the data plate and manual for your own motor and fan before choosing one.

Do I need a different control box for different voltages and phases?

Yes. Control equipment is built for specific supply voltages and for single-phase or three-phase supply, and for a range of motor sizes. Using the wrong one can damage the equipment or be unsafe.

Check the data plate on your fan motor, the supply at the site and the ratings of the control box. If you are unsure, have an electrician or the supplier confirm compatibility before you buy.
