Balls easily, low cost, tends to spit at
higher currents, used for non-critical
welds only.
Balls well, takes higher current, with less
spitting and with better arc starts and arc
stability than pure tungsten.
Higher current range and stability, better
arch starts, with lower tendency to spit,
medium erosion.
Lowest erosion rate, widest current rate,
AC or DC, no spitting, best arc starts
and stability.
Best stability at medium currents, good
arc starts, medium currents, good arc
starts, medium tendency to spit, medium
erosion rate.
Low erosion rate, wide current range,
AC or DC, no spitting, consistent arc
starts, good stability.
Best stability at medium currents, good
arc starts, medium tendency to spit,
medium erosion rate.
Low erosion rate, wide current range,
AC or DC, no spitting, consistent arc
starts, good stability.
Use on lower currents only, spitting
on starts, rapid erosion rates at higher
currents.
Low erosion rate, wide current range,
AC or DC, no spitting, consistent arc
starts, good stability.
Best stability of medium currents, good
arc starts, medium tendency to spit,
medium erosion rate.
Low erosion rate, wide current range,
AC or DC, no spitting, consistent arc
starts, good stability.
Lowest erosion rate, widest current range
on DC, no spitting, best DC arc starts and
stability.
Use on lower currents only, spitting
on starts, rapid erosion rates at higher
currents.
Low erosion rate, wide current range,
no spitting consistent arc starts, good
stability.
Lowest erosion rate, highest current
range, no spitting, best DC arc starts
and stability.
