4.04 GTAW (Lift TIG) Electrode Polarity
Connect the TIG torch to the "-" Negative Output Terminal and
the work lead to the "+" Positive Output Terminal for direct
current straight polarity. Direct current straight polarity is the
most widely used polarity for DC TIG welding. It allows limited
wear of the electrode since 70% of the heat is concentrated at
the work piece.
