摘要

Welding or cutting burner comprises a burner head having a distance measuring device for measuring the distance between the workpiece surface and a part on the burner side using a capacitive measurement. The part on the burner side is formed by an electrically conducting part of the burner nozzle (13) and is electrically insulated from the burner head. Preferred Features: The part on the burner side is formed by the burner nozzle which is insulated from the burner body (1) by an intermediate part (11, 12) made from an insulating and a good heat insulating material, preferably anodized aluminum.
