Abstract
A combustion tool is provided, including a combustion power source with a reciprocating valve sleeve moving between a rest position in which a combustion chamber is open, and a closed position in which the combustion chamber is sealed, a control system operatively connected to the power source, and a trigger switch connected to the control system and providing operator interface with the control system. The control system is configured such that operator manipulation of the trigger switch is the only operator initiated movement required for initiating repetitive spark generation.
