275 Super Electrode
for Outstanding Bead Appearance in Welding Highest Alloy, Carbon
and
Stainless Steels AC
or DC Reverse Polarity (Electrode + ) All Position General
Characteristics All-State®
275 Super is an austenitic alloy deposit with outstanding bead appearance. A high
strength coupled with low
amperage demand has created an excellent electrode for a wide variety of alloy
steels and tools, dies and complicated
sections. A short arc is necessary. Typical

all surfaces to be welded. Preheating is generally not necessary. On some high
alloy steel sections, a preheat
of 300°-500°F (149°-260°C) may be required. Stringer beads
should be used. Allow welds to cool prior to
removing slag.
