Hi all,
Been building up a MIG welder, its a bit of a mix of parts but should all work fine, the point I'm stuck on now is temperature regulation. The overall design I'm using as a basis uses a thermostat to control the temperature by cutting the torch trigger signal, which seems a reasonably sensible method, but since its all based on a wiring diagram I cant really tell much, mainly what temperature the thermostat triggers at (even after a bit of looking around), and where exactly its located in the case. So since I'm doing this from scratch, where do you guys think a sensible location would be? (A brief look around suggests maybe they are attached to the main transformer, I think on the core?) Would also be nice to know what sort of temperature range welder thermostats tend to trigger at so I can source a decent one to use. Or even info about alternative methods of regulating temperature if any exist and are any good?
Thanks!
Edit : Should probably point out its a 220A welder, and running on single phase power. It probably shouldn't matter, since stuff will fail at similar temperatures regardless of power rating, but cant hurt to list it.
