The present disclosure provides a welding system capable of detecting a size of a welding material and automatically implementing appropriate arc starting parameters. The use of fluoropolymer or polymerized silicone optimizes the adsorbed antigen stability upon storage. At an image-recording time, the recording head records an image while being moved at a constant speed by the moving mechanism through a moving region between a recording start position and a recording finish position. When second detection information is stored in the memory, the setting information is acquired from another memory in the camera apparatus. Additionally, embodiments paint at least a portion of the first object as specified by the received request, and render a series of frames depicting the first object, such that the painted at least a portion of the first object is shown as painted when viewed from different perspectives using the augmented reality device.
