  We define affine Super Yangian $Y_{\hbar}(\hat{sl}(m|n), \Pi) $ for affine
special linear superalgebra $\hat{sl}(m|n)$ and arbitrary system of simple
roots $\Pi$ in terms of minimalistic system of generators. We also consider
Drinfeld presentation for affine super Yangian in the case of arbitrary simple
root system $\Pi$ and prove that these two presentations (Drinfeld and
minimalistic) of $Y_{\hbar}(\hat{sl}(m|n), \Pi)$ are isomorphic as associative
superalgebras. We also construct isomorphism of affine super Yangians
$Y_{\hbar}(\hat{sl}(m|n), \Pi)$ and $Y_{\hbar}(\hat{sl}(m|n), \Pi')$ for
different simple root systems $\Pi$ and $\Pi'$. After them we also define Weyl
groupoid as a set of morphisms in category with objects, which are super
Yanginas $Y_{\hbar}(\hat{sl}(m|n), \Pi)$, where $\Pi$ is simple root system. We
describe Weyl groupoid in terms of generators and describe action of these
generators on super Yangians. We describe isomorphisms between
$Y_{\hbar}(\hat{sl}(m|n), \Pi)$ and $Y_{\hbar}(\hat{sl}(m|n), \Pi')$ as
elements of Weyl groupoid.
