WARNING - INSTANT-ON TORCHES
WARNING
The PAC121 hand-held torches and machine torch are instant-on
torches. These torches fire (produce a plasma arc) immediately after
torch switch closure or remote switch closure for a machine torch.
Always hold the hand torch away from your body as a precaution against
accidental torch firing. Be aware of this hazardous potential, failure to
do so can result in serious bodily injury.
The PAC121T torch with safety trigger allows an operator the ability to
safely handle the torch before and after the cut and to minimize the
possibility of accidental torch firing.
