You have to contact your local Argentinian embassy / consulate in Brazil who will determine if you're eligible to get an Argentinian visa.
I'm speculating here but given that you're a non-resident in Brazil, the Argentinian consulate MAY ask you to obtain a visa from your home country, the Philippines.
I understand that you obtained a visa for Panama while being a non-resident in Brazil, but each country has its own rules when it comes to issuing visas.
Your best bet is to contact your local consulate, or even email them, and ask them if you qualify.

For Philippine passport holders, it is possible to get a visa for Argentina while in Brazil. I did this before and it can be expedited same day process. People in the Argentina embassy in Brasilia were very helpful.
