Running 3 phase inverter tig from single phase

[M4TTDUFFY]

Hi folks
My tig arrived but it was not what I paid for, so I now have a miller dynasty 300dx which is 3 phase only. So I need a way of running it off single phase or I will have to sell it. It's a beautiful tig and I used it at a friends on his 3 phase and it lays down a beautiful weld but I don't have 3 phase at home. I've searched the net but all I can find is folks using transformer based machines from 3 phase transformer.
So has anyone seen or used an inverter machine from a 3 phase converter? And if so does it have to be a huge one or is the power need for an inverter significantly less than a transformer based machine?
The tig says it only draws 20 amps running at 300 amps on 3 phase and I won't be using it much past 250.

I've contacted miller to see if I could buy the autolink conversion kit to put inside the tig but they still haven't come back with anything.

Any help would be greatly appreciated

if its not the item you paid for you are entitled to a replacement or refund at the sellers expense.

where did you buy it from.

if the unit claims to draw 20 amps from a 3 phase supply then that is what you need to look for if you want a converter, but if i were you i would send it back as not fit for use/falsely advertised

First thing is put up a decent pic of the data plate.
ive run 3x400v inverters on a smallish rotary converter, buts it depends really on how much fluctuation in voltage the welrer can cope with

There's a pic of the backplate bud.
I have the option to return the machine but it took me weeks to get it delivered so I want to see if I can find a way to use it as I have fallen in love with it haha

Just had a look at the manual, it says there will be no output if the input voltage is outside +-10%
id search, google or whatever for someone who has set it up on a converter of any type, cos it might cost you a fair few quid to find out it wont work right
