Terminal sockets - positive pole (+) and negative pole (-):
In MMA
mode the electrode holder cable is connected to the positive terminal
and the earth cable is connected to the negative terminal and should be
reversed when using scratch start DC TIG in MMA mode. In MIG mode
the polarity cable is connected to the positive terminal and the earth
cable is connected to the negative terminal for all MIG welding
applications, except for gasless flux-core welding where the polarity
cable is reversed and connected to the negative terminal and the earth
cable is connected to the positive terminal.
