I'm perhaps stating the obvious but it looks like an AC/DC TIG machine.
I'm assuming 'remote' is for a pedal. 'Starting' is probably for slope in, which I think is fine tuning the current at the start of weld - and maybe gas flow too. Like wise for 'slope down' which will be for when you're finishing the weld.
do you still have this machine could do with some pics of the ac dc switch wiring mines missing the switch
