Abstract
The invention relates to a hazard switch arrangement for flame-cutting and welding units. As the feeler for detecting mechanical obstacles (14) in the path of the torch nozzle (1), a plurality of feeler rods (7) is provided here. The feeler rods (7) are connected in each case to a plurality of movement switches (holder ring (5), contact ring (11) and feeler rods (7)). The multiplicity of feeler rods and movement switch arrangements guarantees prompt and reliable hazard warning in operation. In a preferred embodiment of the invention, the feeler rods themselves serve as the movement switches.
