Plasma Console Coolant Flow Diagram
As soon as the Plasma Console is supplied with input power, the coolant pump motor turns ON. Coolant pumps
out to the torch and returns back to the coolant tank through the radiators, filter, flow sensor, and IGBTs cold
plate respectively. The pump has an internal adjustable bypass valve set to 225 psi (15.5 bar). There is also an ex-
ternal adjustable regulator, set to 175 psi (12 bar), to bypass the coolant flow if pressure exceeds 175 psi (12 bar).
The coolant flow diagram is as shown in the figure below.
