I have 2 different phase without any neutral can I connect my 1 phase equipment using self made neutral using 2 phase series connections

Neutral comes from your source, a neutral can't be "made".
So the Electric Company only gave you 2 wires to work with?
Is everything 240 Volts?

You can do it but the two hots must draw an equal amount of current,if not things will start to cook.

The poster does not mention where he is or what systems he may have.
"Two phase" could be for real or just a layman's term for center tapped single phase.
If there is no neutral how can either leg draw anything? And if it requires a neutral where would it come from? What is a "self made neutral" anyway? :confused: I don't think the OP knows either.

If it is a straight 240v single phase load (IE: Us or Canada) then there is no chance that it will be imbalanced.

In my opinion the OP's question cannot be answered. It is fatally flawed until he comes back and gives us more detail. This is why I ignored this question until now.
