For reference: Typical welding duty cycle is about 30% for most shop
work.. Time between welds to move things, reclamp, get another welding
rod, etc.

Production welding like building a ship may be up to 80%.

My Lincoln Welder ($250 Home Depot class) is rated only (about 20% or
so: not here) duty cycle at full output (225 Amps). But I rarely use
that high a current for more than a minute or two..

That's why I asked. You can add some forced air cooling and even
bolt large, finned heat sinks to the core to keep the transformer cooler
as long as you aren't pulling moisture or corrosive material through the
welder's cabinet.
