Blasting machine & line tester MARS-2

Blasting machine & line tester MARS-2

USE THE RIGHT TOOL FOR THE RIGHT JOB!  MARS-2 blasting machine is the perfect choice when it comes to mining. The spark proof case can be used safely in higher risk environments that may contain explosive gases.

For the ultimate in safety and convenience, the MARS-2 also has its own built in ohmmeter. Whether you are wiring in series or parallel, you can easily identify short circuits, breaks in the line, unbalanced line loads, and overloaded lines before you attempt any blast. A digital LED readout tells you the exact resistance of the blasting line in Ohms. This technology virtually eliminates misfires caused by detonator wiring problems, which is one of the leading causes of blast related injuries.

The MARS-2 blasting machine also comes with a convenient tri-color battery level indicator lamp to warn you when the batteries are getting low.

The MARS-2 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.
