9.4.2 Igniting the Thermit
®
portion in the crucible
1. Remove the cap from the long life crucible and keep it in your hand or dip
electrodes 40 mm deep through electrode opening of the single use crucible
into the welding portion
2. Push the start button.
The IGN LED flashes. The ignition voltage is now available and the device is ready
for ignition for a period of 30 seconds. Once the device correctly makes contact
with the Thermit
® portion, an ignition is released after one second ignition delay.
Lightly stirring the igniter will increase the likelihood of ignition.
If no ignition takes place after pushing the Start button
(within 30 seconds e.g. due to improper contact with the
Thermit
®
portion), the process is automatically cancelled.
The Thermit ® portion is ignited when the device gives an
acoustic signal and the IGN LED glows constantly. The
operator has two seconds to close the crucible with the
cover or remove the device from the crucible and retreat
to the safe distance.
The reaction of the Thermit
®
portion poses a serious
burn hazard!
Hot electrodes pose a burn hazard!
3. Dip the electrodes 40 mm deep into the Thermit
®
portion.
Bursts of flame pose a serious burn hazard!
4. Immediately close the crucible with the cover and retreat from the device!
