    This Technician’s reference is intended for anyone interested in having a solid grasp of how to use the Brown Firefly Curing System to its greatest potential. It contains useful information on how to optimize curing parameters, explanations of how major sub-systems work and may be tweaked to suit one’s particular needs, and tips to help avoid problems that can pop up any production environment.
