Brazilian Dodge Dart 76 (similar to 69 usa)

According to the machine specification, its rated to weld aluminum and stainless steel.
Of course, I must trade gas to pure argon and use a torch with teflon liner. I can only buy the teflon liner and install in my torch.
I don't know if I need to change polarity, but its quiet easy to do so.

Right now, I'm waiting for mixed gas delivery. I bought this morning and seller said he would deliver by 13pm (about 4 hours ago). No one pays attention to time in Brazil :(
