Is there a data plate on it?
Some of them ran 240v 3-phase not 240v single phase mind...

The first photo, with the multi-pole white connector block, appears to show the power connections to the primary of the small auxiliary power transformer. This is always a single-phase transformer, with typical primary tappings of 110, 220, 230, and 380 , 400, 415 volts, and secondaries of 24v and possibly 42v. As such, it doesn't help to decide whether a "3-phase" welder can be set up for single-phase.
The second and third photos show a contactor, which has only two input wires and two output wires - rather than three. It may be supplying the auxiliary power transformer.
Does the machine have more than one contactor? We need photos showing a general view of the inside, the coil and core structure of the main welding transformer, and the secondary connections at the bridge rectifier. Additionally, as hotponyshoes said, a picture of the data plate.
A lot of "3-phase" welders actually just use the higher supply voltage that is available across two phases, but unless the primary winding(s) of the main transformer can be tapped for 230v or wired in parallel, they will not work on domestic 230v mains.
If the "300S" of the Cebora product name means this is a 300-Amp MIG, it is unlikely that it can run on single-phase 230v mains.

It might be that it can run single phase at 400v.
The ones I have seen will run 3-phase at 230v or 400v etc.
I've never seen yours but that might well go the other way around.
If it's a 300a machine I'd expect it to support 400v.
The data plate will tell you..
