Abstract: A hand held compressed air powered crimping tool is used both to secure ring tongue terminals to stripped electrical wire ends, and to secure butt splices that join together two electrical wire ends. The dies used, their locations, their retention, and their movements are similar to existing "T" head crimping tools, which are finger and hand manipulated and powered. When using this compressed air powered tool, pre-positioning is still undertaken by fingers and hands, of wires, ring tongue terminals or the butt sleeves, and insulation covers, to be crimped. Continued finger and hand movements, move together respective "T" head portions to preliminary keep together all the members to be crimped, in their respective positions. At the conclusion of the preliminary positioning, no spaces are left around dies for any unwanted entry of finger portions of the operator.
