Using the control unit, press the button and hold,
while you observe the “ready” indicator light. A
green light will blink for a few seconds and then
will change to a constant light. At this time, the unit
will send a charge to the ignition strip. The ignition
strip will spark inside the metal cup, initiating the
CADWELD ® PLUS exothermic reaction.
Allow approximately 30 seconds for completion of
the reaction and solidification of the molten material.
