By controlling pressure to a cylinder, Proportion-Air can provide weld tip force control in remote welding applications. A number of options and modifications are available to improve feedback and data acquisition during this process.

The QB2 comes with either a voltage or current analog monitor signal to provide a feedback signal to the controller indicating the actual pressure being applied. Additionally, the QB unit will have the option of adding transistor-to-transistor logic, which consists of a green LED on the top of the QB can.

When the desired pressure has been achieved, the LED will illuminate. Since the QB is immune to vibration, and has an optional radio frequency (RF) filter, the QB can be mounted as close as possible to the weld head, thus giving a quicker response time.
