I've just bought a Dynasty 350 for myself and got it set up yesterday.
I know the 350 gives the option on what polarity the electrode starts with.
Is there a rule of thumb whether it should be positive or negative?
I'd like to experiment with both polarities but is this only applicable when the machine is set for differing EN/EP percentages or is it applicable to all AC welding on the machine and on all waveforms?
