Blasting machine GUERILLA
SAFETY FIRST! GUERILLA blasting machine features a built in line resistance checking system. Now you can easily identify short circuits, breaks in the blasting line, or overloaded circuits before you attempted to blast. This technology virtually eliminates misfires caused by detonator wiring problems, which is one of the leading causes of blast related injuries.
The GUERILLA blasting machine has temperature compensating circuits to facilitate cold weather operation, and a safety feature that automatically drains the blast capacitor when the Line-Test switch is pressed. For added safety blasting will only occur if the two separate FIRE switches are pressed simultaneously.
The hermetically sealed case made of non-conductive plastic, exceeds all NEMA standards and is rated at IP65 under the international standard IEC 65029. This means the blasting machine case is splash proof, dust proof and spark proof. It can be used safely even in higher risk environments that may contain explosive gases.
The shielded terminals on top facilitate the quick and safe connection of the electric detonator leads, and guard against shocks.
