First try at melting metal

Often the easy way to regulate flow when using a centrifugal blower is by use of a butterfly valve, as RPM vs flowrate curves are far from linear and with little back pressure just plain difficult to manage, but, with a correctly sized butterfly; a closed butterfly is closed and at half open the flow is around half of full flow and open is full flow.
