11.2. Welding torch
Part Check Remarks
Nozzle
1. Check if the nozzle is fixed firmly
and distortion of the tip exists.
Possible gas leakage occurs due to the unfixed nozzle.
2. Check if there is spatter sticking on
the nozzle.
Spatter possibly leads to the damage of torch. Use
anti
‐ spatter to eliminate the spatter.
Contact tip
1. Check if the contact tip is fixed
firmly.
Unfixed contract tip possibly leads to unstable arc.
2. Check if the contact tip is physically
complete. The physically incomplete contact tip possibly leads to
unstable arc and arc automatically terminating.
Wire feeding
hose
1. Make sure that there is the
agreement of wire and wire feed
tube.
Disagreement of the diameters of wire and wire feed tube
possibly leads to the unstable arc. Replace it/them if
necessary.
2. 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.
3. 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.
4. Check if the wire feed tube and
O ‐ shaped seal ring are
physically complete.
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.
Part Check Remarks
Diffuser
1. 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.
