ABSTRACT:
The present invention relates to a strain relief mechanism for a plasma arc torch. In particular, the invention relates to a strain relief system including a positive axial restraint component for restraining axial movement of a lead relative to a housing and a positive rotational restraint component for restraining rotational movement of the lead relative to the housing, wherein the positive axial restraint component and the positive rotational restraint component are independent components arranged in a spaced relationship relative to each other.
