re: Unkown 18" metal bandsaw

Yes, the light is attached. If you zoom in just below the switches, there is a clamping system as well as welder/annealer. Designed so that if you buy blades by the roll, you cut it to length, clamp it that little jig, anneal and weld all with the push of a button. I’ve got it to weld but haven’t perfected a decent weld with it. There is a certain time that is has to be annealed etc in order to work properly. I only go through a couple of blades/ year so I just order them already welded
