4.06 GTAW 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.

Electrode
E6011 This electrode is used for all-position welding or for welding on
rusty, dirty, less-than-new metal. It has a deep, penetrating arc
and is often the first choice for repair or maintenance work.
E6013 This all-position, electrode is used for welding clean, new sheet
metal. Its soft arc has minimal spatter, moderate penetration and
an easy-to-clean slag.
E7014 All positional, ease to use electrode for use on thicker steel than
E6013. Especially suitable sheet metal lap joints and fillet welds,
general purpose plate welding.
E7018 A low-hydrogen, all-position electrode used when quality is an
issue or for hard-to-weld metals. It has the capability of producing
more uniform weld metal, which has better impact properties at
low temperatures.
ENi-Cl Suitable for joining all cast irons except white cast iron.
E318L-16 High corrosion resistances. Ideal for dairy work etc.
