If you look in the spec sheet, they show details of the toroid.
The "dot" near each winding shows the way the windings relate to each other.
This is important in the primary in this case as you will be using both windings in series for your 240v.

So primary side, connect one incoming 240v line to say the brown wire.
The Violet and Grey will connect to each other and insulate in a separate connector.
The Neutral of the 240v supply then goes Blue wire.

Of the secondary, Orange and Yellow can connect to say the original Brown pair, and the remaining Red and Black connect to the Red pair. No difference which way around.

Now a word of caution here as the secondary two sets of cables MAY be connected to form a split supply within the welder.

Under normal circumstances, if this were the case, they would bring out just 3 wires, but check anyhow.

Check with a multimeter set to low ohms scale, for any connection between the welder cables Brown and Red.

Oh, by the way, it also shows the weight at 0.8Kg so not "small" by any means.

Thanks for the advice on the connections. greatly appreciated. I have checked with the voltmeter.....there is no resistance between any of the four 24V output red and brown wires!

I hope you mean there is no conductivity. If there is really no resistance, then you probably have shorted rectifiers.
