In general when using the machine for MMAW (Stick) the electrode holder is connected to the 
positive (+) terminal and the work return to the negative (-) terminal.   

 

In general when using the machine for GMAW (Mig) the MIG Torch should be connected to the 
positive (+) terminal (Euro Connector) and the work return to the negative (-) terminal. 

 

In general when using the machine Gasless Mig the Mig Torch should be connected to the 
negative (-) terminal (Euro Connector) and    the work return to the positive (+) terminal.           

 

When using the machine for GTAW (TIG) welding the TIG torch should be connected to the 
negative terminal (-) and the work return to the positive (+) terminal 

 

Always consult the electrode manufacturer’s data sheet if you have any doubts.
