PONGO Push-Button Blasting Machine
The firing line is connected directly to PONGO’s two binding posts. The energy for the blast is generated by firmly pushing the shaft button of the device; an external power supply or batteries are not needed. The device includes an R-type safety pin that prevents the release of the button until the operator is ready to detonate the explosives.
PONGO supports blasting of up to two Class 1 detonators in series, with up to 120 m total line length and 1 mm² cross sectional copper cable. The total blasting line resistance should not exceed 11 Ω.
To test the line resistance, Englo’s OOM-4 digital line tester should be used.
PONGO is a multi-use device and can be used up to 1000 times or more. After each firing the device can be readied again by pulling the shaft button up to the cocked position.
