Comment on Microvawe transformer spotwelder. Is there a way to improve it?

If it’s a 240v transformer, the primary will have less turns than a 120v one. You may not have a high enough voltage at the secondary because of that.

Would trimming down the voltage with on the primary with a triac would help?

You need to go up in voltage, not down.
Try it on 240v. (check your 5v supply can handle that, or power it separately)

I have 230V or 400V three phase. I live in the EU. So this cannot be solved without replacing the winding on the transformer I guess.

If you have a 230V supply and a 230V transformer, you are fine. I believe they thought you were using a 120V supply on a 230V transformer.
Raising the input voltage will probably not get you what you want.

If it’s just a matter of getting a larger voltage, then you already got 400V. No need for new windings, unless the insulation on the primary can’t handle 400V.
