MIG welding is usually globular transfer. ( autobody work would not use spray transfer)
The end of the wire melts into a little ball and drops to the weld zone.
In most usages there is no contact between the wire and the base metal for more than a few milliseconds at a time as it creates its short circuit.
I would think you will be lucky if you can get consistent "sticks".
Going to be an interesting experiment. Keep us posted

Edit: most MIG machines today use a short circuit globular transfer method, which is not true globular transfer. It is in those milliseconds that the wire contacts the base metal and creates the short circuit which increases the heat and forms that nice little ball (glob) of metal to transfer.

That is a basic idea , there are many text books explaining it far more involved.
