Blasting Machines and Line Testers

Purpose: Used to safely initiate controlled explosions and test electrical blasting circuits.

Blasting machines: Hand‑cranked or electronic devices that generate a high‑voltage pulse to detonate detonators.

Line testers: Verify continuity and integrity of detonating cord or electric blasting circuits before firing.

Safety features: Short‑circuit protection, insulated handles, clear polarity indicators to prevent accidental detonation.

Applications: Mining, quarrying, demolition, military training, and controlled demolition operations.

Maintenance: Regular inspection of contacts, cables, insulation; calibration checks for reliable output and safety compliance.
