415v 2 Phase 16 Amp Demag

Good morning all, I'm in the UK and have a query i was hoping someone maybe able to help me with.

My company has a 415v 2 phase 16 amp frequency 50 Demagnatiser unit that has been replaced, and they would like to make the old one mobile. The problem is that our site only has 415v supplies in the maintanances department for the welders. Currently if the electricians require a welder in different areas they wire a circuit board straight into the mains and then removed it. Obviously if you have to put 415v supplies all over the factory then you may aswell have just had it fixed in one place, I was wondering if there was any way to be able to run it from a standard 240v socket, perhaps incorperating a transformer into the unit?

My electrical knowledge is very limited; one of the onsite electricans will be doing any work but have been less than helpfull coming up with anything.

Any input would be greatly received, cheers
