section 4
The Remote Arc Starter Box is more commonly referred to as the RAS Box. The RAS Box serves as an interface
between the Vision 50P CNC and the EPP family of Plasma Power Supplies, helping to deliver the plasma arc.
The RAS Box also provides a voltage feedback to the plasma torch lift. This voltage is used to regulate the torch
height while cutting, maintaining the proper height of the torch above the work piece.
Within the RAS box there is an ACON module for communicating with the CNC, a High Frequency/Voltage Di-
vider circuit board which functions to provide pilot arc ionization and voltage divider functions to regulate torch
height.
Coolant connections and torch power connections are made within the RAS box and provide an interface be-
tween the power supply, coolant circulator and the torch.
