unstable arc and arc automatically terminating.
Disagreement of the diameters of wire and wire feed tube
possibly leads to the unstable arc. Replace it/them if
necessary.
Bending and elongation of wire feed tube possibly leads to
the unstable wire feed and arc. Replace it if necessary.
If there is dust or spatter, remove it.
The Physically incomplete wire feed tube or O-shaped seal
ring possibly leads to the excessive spatter. Replace the wire
feed tube or O-shaped seal ring if necessary.
