General Characteristics
Amazing Smoothcote®
Plus stainless steel electrodes are formulated with a heavier coating to optimize
operation in
the flat and horizontal positions. Beads produced are concave and finely rippled.
Spatter is low and does not adhere
to the plate. Slag is virtually self-removing. Cleanup time is minimized. The
3/32" diameter is in a 12" length
made possible by the superior heat
resistant coating. Typical
Applications Formulated
for outstanding bead appearance and operator appeal when used in the flat and
horizontal positions. Especially
useful in food, chemical, and medical equipment applications where weld appearance
is important. Little,
if any, grinding or polishing is required. Qualities
