A welding user interface device, comprising: an optical sensor, an augmented reality controller, a graphics processing unit and a display, wherein - the optical sensor is configured to collect an image of a weld environment; - the augmented reality controller is configured to, based on the image of the weld environment and first instructions that correspond to a weld operation in the weld environment, determine a simulated object to be presented in a field of view, a position of the simulated object in the field of view, and a perspective of the simulated object in the field of view; - the graphics processing unit is configured to render the simulated object based on the perspective to represent the simulated object being present in the field of view and in the weld environment; and - the display is a semi-transparent display to present the rendered simulated object within the field of view based on the position determined by the augmented reality controller, at least a portion of the weld environment being observable through the semi-transparent display when the display is presenting the rendered simulated object, characterized in that the optical sensor includes a filter configured to mitigate radiation at an arc radiation wavelength, a light pulse illuminator configured to output second radiation at a second wavelength outside of an arc radiation spectrum,a 3D time-of-flight,ToF, depth sensor configured to collect signals at the second wavelength to generate the image, an analog front end and ToF controller circuitry configured to control the light pulse illuminator and the 3D ToF sensor via the analog front end and to synchronize the operation of the TOF sensor, the analog front end and the light pulse illuminator; the analog front end being an array of sample-and-hold and high speed analog-to-digital converters, ADCs, for analog to digital conversion and serialization of time-of-flight depth data, ToF controller circuitry further configured to acquire the serialized depth data from the analog front end into a collection of 3D points forming a depth map and to render the depth map into a 3D space and to convert it into mesh models which are transmitted to the augmented reality controller, the filter comprising a bandpass filter to permit the second wavelength while mitigating the radiation at the arc light wavelength. an optical sensor, an augmented reality controller, a graphics processing unit and a display, wherein - the optical sensor is configured to collect an image of a weld environment;
