- Never cover the end of the barrel or point the gun at any object closer than 1" from the

end of the barrel. Covering the end of the barrel could result in a jam which may result in

a serious fire or explosion of the IGBTs and/or driver coils.

The EMG-01A is a fully automatic electromagnetic gun – its core component is a

sequence of optically gated, IGBT switched driver solenoids. As a projectile passes through the

barrel, it triggers optical gates which send signals back to the microcontroller. The

microcontroller quickly interprets these signals and directs the coils to turn on in a precise

sequence. This accelerates the projectile down the barrel and out of the gun with an exit

velocity of roughly 45m/s.

While its muzzle energy is comparable to most bb-guns (around 5 joules or 3.7 ft/lbs), it

should be treated the same way as a firearm: with the utmost respect. While the muzzle

energy is roughly the same as a bb-gun, the projectile mass is far higher. Hazards from

accidental discharge include broken bones and severe injuries – in short, never point the device

at anything you don't want to destroy. Treat it as loaded at all times.

The device operates on low voltage (25V), but carries extremely high amperage (300A+)

during a shot, which is immediately converted to high voltage (300V+) in the driver coils and is

discharged through freewheel diodes at the top of the driver coil stages. Never touch any

metal parts of the gun during a shot, especially those near the barrel. 300V is more than

enough to cause serious electrical shock, personal injury or death. The high voltage

components (IGBT collector pads) are covered in amber high voltage Kapton tape for your

protection and for the protection of the microcontroller from high voltage spikes. NEVER

REMOVE THIS ORANGE TAPE FROM THE IGBT COLLECTOR PADS. If it falls off for any reason,

discontinue use of the device and send the device back to Arcflash Labs, LLC for repairs if the

tape falls off for any reason. It is a simple repair. Firing the device with no tape on the pads will

almost certainly lead to severe shock and/or irreversible damage to the gun.

2.2 Injector

- Never stick any object or any part of your body in between the injector and the breech.

Projectiles are pushed out of the magazine by a small captive solenoid, known as the

injector. This solenoid is a very low power device. For comparison: the injector operates on

roughly 1 ampere while a single driver coils draws roughly 300 amps. This injector has a spring

loaded mechanism which allows it to return to its home position. It is this spring return

mechanism which sets the maximum rate of fire of the gun. 8 rounds per second is the

maximum safe rate of fire of the injector, and hence the maximum rate of fire of the EMG-01A.
