Jiangdong Machine tool Turret Milling Machine HX30 info required

I now have a Jiangdong HX30 milling machine and have no information about it. A google search doesn't seem to find any information but I was told that these machines were imported and resold under different badges but I don't know the names.
It is a 240v 3 phase machine using a CAT40 tool holder system. However the only holder I got with it doesn't have a pull stud and the head seems to use a traditional Bridgeport style drawbar through the top. It is a large machine and tightening the drawbar would require a ladder. There is no drawbar so I don't know if this is the correct method.
It starts up but there is a lot of flickering of the lights and arcing. I'm using an American Rotary phase converter with a separate idler motor rather than a VFD.

I have owned a genuine Bridgeport mill, LeBlond lathe, Clausing Surface grinder in the past, but had to leave them behind due to a cross country move.

Any help would be appreciated.

Looks like a bad contactor. It sparks and then eventually closes as the motor gets up to speed.
Several of the small glass fuses are blown and a lack of a bulb in the indicator light on the main panel 'might' be a problem.
The knee motor seems to be getting power but nothing is happening.

Ha you in fact verified it is wired for 240 volts? i recently had experience with a lathe that would run for a short time (10-15 minutes?) then the heaters would drop out the relays. The motor WAS WIRED 240 volts but had heaters for 480. Changing the heaters fixed it.

I have seen similar machines with an #40 Milling Machine or ISO 40 taper, and they often had an add on power draw bar using air or electric to avoid the need for a step ladder, but a new one, while they appear to be nice to use, would cost a fair bit I would imagine .
While I have seen one used, I have never used one myself.
A collet chuck would be helpful if tools you need for the work you are doing will fit in the collets.

The motor data plate says 220/380v and the orange sticker on the head says 240 volts.
However, work has been done on this machine and it is not in a stock configuration any more.
The power downfeed doesn't work.

I'm considering a full CNC conversion for this machine. The frame is about twice the size of a regular Bridgeport and should have enough rigidity.
The pulley that slides up and down depending on the speed range needs a new bushing. (I forget the correct name of it.) The two drive belts look fine, but the pulley is what is calling the clattering noise in the head. Initially I thought it might have been a loose drawbar, but there isn't one there so that can't be it.
I doubt that I will be able to find a rebuild kit for it so I will likely have to make the bushing on my South Bend lathe. This is also an auction purchase and I finally got to test it along with the mill when I got the sub panel installed in the shop.
I have done one complete teardown rebuild of a variable speed Bridgeport series one, so I have a rough idea of what work is involved.
