The temperature mode of a metal contact upon transition 
to a hybrid and further on to a plasma one has been studied. Spatial 
(three-dimensional) mathematical modeling confirmed the existence 
of a dependable metal contact before melting of the anchor material 
and transition to an arc mode of passage of the current after the 
onset of boiling. The possibility of destruction of the accelerated 
body during the acceleration time has been investigated.
