pivot arm 140 a nozzle 155 an igniter 160 a guide tube 165 a limit switch 170 a magnet 205 valves 175 a computer radio frequency controller 180 and optionally a sensor 185 a motor 190 and a spring 210 the frame 105 is any mounting structure which may be a flat plate or a box preferably there is an opening in the frame 105 for the flame to extend from the nozzle 155 and out past the frame 105 so as to be able to burn the metal enclosure to which it is attached if the frame 105 is a closed box with no opening then the flame from the nozzle 155 would first burn through the box and then engage the metal enclosure the frame 105 at least has a top surface 110 on which to mount the components of the portable gaseous injector 100 when the frame 105 is a box the components may be mounted on any inside wall of the box air vents 405 as shown in fig4 are preferable to prevent overheating inside the box the frame 105 has a bottom surface 115 preferably a bottom planar surface which includes a magnet 205 the magnet 205 is present so that the frame 105 can be magnetically attached to a metal enclosure which is made of magnetic metal 505 examples of a magnetic metal 505 include iron nickel cobalt gadolinium and alloys thereof once attached on the metal enclosure the portable gaseous injector 100 is operable to cut a hole through a wall of the metal enclosure and then inject a fluid into the metal enclosure the miniature cutting torch 120 is mounted to the frame.
