Noooooo!
The variable transformers are connected in autotransformer configuration and
there is NO isolation between the primary and the secondary. This is first
of all a safety issue and a major one!
Second, if you connect them the right way up, with both commons together,
you can adjust the sliders to obtain you required voltage between them but
the output will float at about 110V AC relative to ground.
Given the fact that one of the main reasons we use transformers is to
provide isolation, your proposal is self defeating: working with a hot piece
of equipment is something probably beyond your competence. Don't fool
around: it kills.

Subject: [Amps] transformer in series.........
HI
i hav a problem related to transformer
i have two identical transformer with variable output 0-130 volts and
current of 10 amp. the input of the transformer is 110 volts. problem is
that i hav an input source of 220 volts. is this possible, if i connect them
in series so that the input voltage is equally divided (110-110 volts) into
the two tranformers and i get desired 10 amp, is this the safe
approach......?
