Blasting Machine BB-75

Blasting Machine BB-75 is an advanced, compact high-energy capacitive discharge blasting machine capable of initiating a minimum of 75 EBCs (tested through 340 ohms). Bridgewire and firing line continuity is testable through the integrated haptic (tactile feedback) circuit tester with redundant LED. Intrinsic safeties include automatic abort, internal shunt, boot-protected switches, touch proof output terminals with downward facing inputs, and fuse protected testing circuit.

Blasting Machine BB-75 unique features:

• Connect firing line to high-voltage binding posts
• Hold down ARM switch to charge blasting circuit
• Once the Super-Bright “Ready” LED lights solid (flashes during charge), press FIRE button to send high-energy pulse down firing line

Intrinsically safe design:

• Internally shunted output terminals help protect EBCs from stray EMI – remain shunted until instant of firing
• Auto abort discharges the capacitor upon release of ARM button (prior to firing)
• Bridgewire testing circuit current is less than 1 mA (795 microamps average)
• Fuse protected testing circuit cannot provide more than 50 mA (serial numbers 100+)
• Touch-proof output terminals with downward facing inputs reduce risk of shock

Rugged enclosure:

• IP51 Compliant
• Black ABS case with bright-red/orange rubber boot, and sealed switches
• Shock and weather resistant (not designed for wet use due to high-voltage output)
