of colors of case or buzz presents.
Check if gas connection is available, case, and other joints
are in good connection.
Check if the nozzle is fixed firmly and
no distortion of the tip exists.
Possible gas leakage occurs due to the unfixed nozzle.
Check if there is spatter sticking on the
nozzle.
Spatter possibly leads to the damage of torch. Use anti-
spatter to eliminate the spatter.
Check if the contact tip is fixed firmly.
Unfixed contract tip can lead to unstable arc.
Check contact tip is within working
tolerances.
The physically incomplete contact tip can lead to unstable
arc and arc automatically terminating.
Check torch liner can take selected
diameter wire
Disagreement of the diameters of wire and wire feed tube
possibly leads to the unstable arc. Replace it/them if
necessary.
Make sure that there is no bending or
elongation of wire feed tube.
Bending and elongation of wire feed tube possibly leads to
the unstable wire feed and arc. Replace it if necessary.
Make sure that there is no dust or
spatter accumulated inside the wire
feed tube which makes the wire feed
tub blocked.
If there is dust or spatter, remove it.
Check if the wire feed tube is physically
complete.
The Physically incomplete wire feed tube possibly leads to
the excessive spatter. Replace the wire feed tube or O-
shaped seal ring if necessary.
Make sure that the diffuser of required
specification is installed and is
unblocked.
Defection weld or even the damage of torch occurs due to
the non-installation of diffuser or the unqualified diffuser.
