We present spectra of highly charged tungsten ions in the extreme ultra-violet (EUV) and visible range observed by using two types of electron beam ion traps. The electron energy dependence of spectra is investigated for several electron energies from 630 to 3200 eV. Several tens of previously unreported lines are presented in the EUV and visible range, and some of them are identified by comparing the wavelengths with theoretical calculations.
