Steady state micro welding
From Tardis Wiki, the free Doctor Who reference
Steady state micro welding was an advanced engineering technique pioneered by the Lamadines. The Third Doctor used it to try to repear his Dematerialisation circuit. When smoke started to come from the circuit, Jo Grant thought it would start a fire, but the Doctor said that steady state micro welding "always produces more smoke then fire".
