33 lb (15 kg) spool PRSS222112-729

CHARACTERISTICS
No shielding
• Limited multi-pass, all-position wire
gas needed
• Can be used on up to 3/4" thick steel
• Can be used with CC power sources, provided the
power source can produce a low voltage range between
14 – 19 volts and uses voltage sensing wire feeders
• Uses DCEN polarity
• Smooth arc and low spatter emission
ProStar FC-SS-11 wire is versatile with enhanced FILLER METALS
operator appeal because of its smooth arc, low spatter
emission, and overall ease of handling. It's a good choice
for hard-to-reach locations, or where provisioning of
gas cylinders is not practical. It's also effective in windy
or adverse conditions when mechanical properties are
of less concern. FC-SS-11 has little tendency to burn-
through, and is well suited for butt, fillet, and lap joints on
steel thicknesses from 16 ga to 3/8". Not recommended
for welding steel thicknesses greater than 3/4". For welding
3/8" – 3/4" steels, a preheat temperature of 325 °F is
advisable. Recommended for single- and limited multi-
pass welding in all positions using no shielding gas.
