Hobart T225 info or manual

[Lbaron54]

Sorry but I'm new and would like some information on an old Hobart T225. It was given to me and the ID plate is missing off the front. So I would like to know what size breakers do I need and what size cable and maximum length.

I'm not sure what they draw at the top end, but 96% of these types of old machines are probably on a 50A breaker and #10 copper wire (or even #12). If you want the circuit to be able to be used for anything other than a welding machine, then you should use #8 copper wire. If using a cable, you would want 10/2 w/ ground, which is two hots, plus a green or bare ground. You want a 2-pole breaker for 240V, assuming a typical American panel.

On the front end, you want welding leads with Tweco style connectors, I believe.

Here's a copy of the nameplate of one. Looks like top-end input (welding at 225A, which is A LOT) would be about 53A if you have typical American 240V input. So the 50A breaker will easily do everything that machine can do within its duty cycle of 20%

Thanks for that info, does anyone know what size welding cable and the maximum length this welder would have used.

Just search up a few welding lead amperage charts and compare enough of them to get a good consensus. Here's an example from the top of the search pile:
