PORTABLE IGNITION CONTROLLER

A portable exothermic welding ignition controller includes a housing configured to receive a first portion of a portable power tool battery with a second portion of the portable tool battery external to the housing. A circuit board is positioned within the housing and configured for electrical coupling to the portable power tool battery. An actuator is operatively engageable with the circuit board for selectively discharging power from the portable power tool battery to a connection terminal electrically coupled to the circuit board.
