Stainless Steel Welding Electrodes
127(E309L-16) - Isoarc 127

Characteristics
Isoarc 127 features low spatter loss and excellent slag removal. The work surface is smooth and finish free of undercut. The electrode is free from porosity.

Applications
Isoarc 127 is a highly alloyed low carbon electrode designed for the dissimilar welding of stainless steel to mild steel or low-alloy steels. It is also well suited for buffer layers when overlay welding on mild steel, giving an 18Cr 8Ni deposit already in the first layer. It can also be used for welding high temperature steels.

Procedures
To avoid heat accumulation, use low amperage with stringer bead technique. Hold a short arc and remove the slag after each pass. On DC Equipment use positive polarity.

Redrying
If moist re-dry at 350deg C for 1 hour.
