ABSTRACT:
There is provided a powder actuated tool effective to drive a metallic fastener into a workpiece, for example, a nail gun. The pressure to drive the fastener is generated by combustion of an flammable propellant mix that is ignited by a primer flash. The primer flash having been generated by ignition of a combustible gas by discharge of an electric arc in the tool barrel. The combustible gas is lead-free such that the operator and the environment are not exposed to dangerous lead residue during use. The use of a solid propellant generates higher pressure and more effective driving of the metallic fastener than is achieved with powder actuated tools driven solely by combustible gases.
