plasma cutter connection and config

Hi Mike,

We wouldn't advise using the WorkBee with a Plasma cutter, due to the wheels and other parts being plastic, that splatter will damage them.

In addition, Plasmas normally require torch height control, this is not something our controller supports.

A plasma cutter uses arc voltage to maintain a consistent distance from the plate while cutting. The controller we use has no way of reading this arc voltage, therefore it cannot automatically control the height.
