Arrangement for selective firing of IR-torches comprising an interchangeable magazine having cartridges each of which holds a predetermined number of the torches. The cartridges are positioned in corresponding tubular frames of the magazine. A mounting ramp is provided with a central guiding pin and a polar guiding pin to be fitted into corresponding recesses of the magazine when mounting the same. Each cartridge is provided with electric connecting means in the shape of concentric contact rings, the number of which is at least one more than the number of torches of the cartridge. The rings are provided on a plate at the end of the cartridge and are put into electric contact with corresponding point-shaped contact elements of the ramp during mounting of the magazine onto the ramp.
