The fix/weld was made in fact with acetylene gas and copper wire! ( dunno how you call that kind of welding job ). That is not posible with aluminium.
( my car is 1k miles from home )
not doubting you at all nacho. just stating my personal experience.
today, there are so many methods of joining, or repairing, unlike materials, [with, or without heat] and since i wasn't there at the time, i can only guess.
my only question is whether your original was "iron".
i'll bet our individual interpretation of material is what is causing the confusion.
"iron" to me is usually a part made of the same [type] of material an intake or exhaust manifold is made out of, or brake master cylinder, of which parts are cast.
to cast, or form, an "iron" condenser would be quite the task, plus be brittle in use as i have previously stated.
steel, on the other hand, would be easy to fab into a condenser, and be very rugged in use. i'll bet that is what you have, and i have lost that fact in translation.
sorry if i have unnecessarily ruffled your feathers ! that was not my attempt. please forgive.
