Small balls of molten metal which come out of the arc. A little quantity
is unavoidable, but it should be kept down to a minimum by selecting
correct settings.
Can be caused by moving the torch too fast.
Can be caused by moving the torch too slowly.
It can be caused by wire feed slipping, loose or damaged welding tip,
poor wire, nozzle held too close to work or voltage too high.
It can be caused by moving torch too fast, too low voltage setting or

incorrect feed setting, reversed polarity, insufficient blunting and
distance between
strips. Take care of operational parameters
adjustment and improve the preparation of the workpieces.
It may be caused by moving the welding torch too slow, too high
welding power or by an invalid wire feeding.
It can be caused by nozzle too far from work, dirt on work. Remeber
that the current of welding is appropriated to the wire you are using.
It may be caused by an insufficient welding voltage, irregular wire
feed.
