<p>The invention relates to a monitoring module (1 . . . 1″) for monitoring an electric arc machining process, said module comprising a camera (2), a photo flash lamp (3) and a control system (4) that controls the photo flash lamp (3) and a control system (4) that controls the photo flash lamp (3) in such a way that it illuminates when the camera (2) records the image. According to the invention, said components (2, 3, 4) are arranged in a common housing (5), which comprises a compressed air connection (6) and an air outlet (7) or a deflection device arranged at the housing (5), which is provided for the orientation of the discharging air beam perpendicular to the optical axis (A) of the camera (2). Furthermore, an air flow caused by the compressed air is led via the light source (3) and/or the control system (4) and/or a charging connection (8) for the light source (3).</p> |
