I think there's some confusion here.
There are two main ways to hit elemental damage:
1. Elemental build-up on a machine's body leading to a status condition, e.g. hitting enough cold arrows until a machine turns brittle, shock arrows until it gets stunned, etc. This mechanic existed in Horizon Zero Dawn as well but I don't think the machines had weaknesses and resistances, so the build-up rate will be different in this game, depending on the machine. I don't know if resistance just slows the process down or nullifies it completely. I think the former but I'd have to test it.
2. Shooting specific parts to trigger a large explosion, which works exactly the same as in the first game. You shoot a blaze canister with fire, it will explode and inflict burn on the target and surrounding machines.
The reason @Nanook said normal arrows seemed to do more damage is probably because they were looking at raw damage instead of status build-up. You don't hit a machine with its weakness to do raw damage, you do it because it's easier to build up the status. Once the status is hit (the icon gets filled), you benefit from whatever status was inflicted.
Is that what the little up arrow is on the bottom arrow? You get like a normal fire arrow for 20dmg, then below there is another dmg icon with an up arrow an around 80dmg? So it inflicts 80dmg when it's on fire?
If so, the basic arrows are still better unless you inflict fire super quick?
I just use the elemental arrows again their canisters or whatever cause a boom, then smash them with the high dmg arrows.
It's quite badly explained in the game I thought. You can muddle your way through no problem though.
