Problem Cause/Correcve Acon
Excessive Spaer -
scaering of
Molten metal parcles
that cool to solid form
near weld bead.
Wire feed speed too
high. Select lower wire
feed speed.
Voltage too high. Select
lower voltage range.
Electrode extension
(sck out) too long.
Use shorter electrode
extension (sick out).
Work piece dirty.
Remove all grease, oil,
moisture, rust, paint,
undercoang, and dirt

and/or prevent dras
near welding arc.
Dirty welding wire. Use
clean, dry welding wire.
