Ion charge state distributions of vacuum arc plasma have been investigated using a time of flight method. It was found that the fraction of high charge components increased using an external strong magnetic field and high arc current. Compared with {open_quotes}conventional{close_quotes} low current arc parameters (zero magnetic field, arc current less then 300 A) in the parameters range investigated (magnetic field up to 10 kG, arc current up to 4 kA) the mean ion charge state increased by a factor 1.2 - 2.5 depending on the cathode materials and discharge external conditions. External magnetic field and a high arc current influence the charge state distribution in a similar way.
