So we were testing the newly built plasma jet last Friday, which necessitated disconnecting the old jet head because there's only one power supply and gas line. The new jet head wouldn't work for some reason, so we had to stick the old one back on. Except the old one doesn't work either now because when we were unplugging it the first time, one of the copper wires that provided the voltage difference across the head broke. So there was some soldering on Friday as well and hunting for the correct type of wire, but still to no avail, because for some reason the Forward and Reflected powers are the same whenever you plug the old jet head in, when in fact Reflected power needs to be about 10% of the Forward to generate the plasma sheath.

Oh dear.

Well... let's see if we can at least get it working again today... I doubt there'll be much time for experimentation.
