Fire apparatus. Brews in three at 100-110A. The adjustment knob does not turn more than 180A, but I think this is not an indicator, and there is enough power reserve. Easily fits together with wires in a welding mask. The wires are normal copper. I have not tried continuous welding, according to the passport at 100A you can cook without interruption.
I have included some photos to accompany my review and provide a better understanding of my experience.
