Lincoln Electric SVM104-A Welder User Manual


 
6. Use nozzle with the largest orifice that gives
the best cut for the work being done. This pro-
duces the best work results and consumable
life. As the size of the nozzle orifice increases,
its current capability increases. Therefore, the
nozzle used for cutting or gouging work must
be able to handle the current needed to give
the best cutting results. A nozzle working
beyond its current capability overheats caus-
ing poor performance. Never use the .035
inch (0.8mm) nozzle when the current output
is above the yellow current range.
7. Use the S24114 Drag Cup when the output
current is in the red range to protect the torch
from dross and the effects of improper arcing
conditions.
NOTE:The S24114 Drag Cup should not be
used at very low outputs.
8. Do not allow your body or the torch cable to
touch hot surfaces.
9. Refer to the User Chart Range guide on the
machine's nameplate for recommended out-
put current ranges for the thickness of the
metal being cut.
Cutting Thin Gauge Sheet Metal
1. Set the OUTPUT CURRENT CONTROL out-
put at mid-range (Yellow range) or below.
2. Pierce a hole in the metal surface to start the
cut. Then, lightly touching the nozzle to the
metal surface, drag the torch along the cut
line.
3. Use the .035" (0.8mm) nozzle for fine cuts.
Larger nozzle sizes work better and provide
longer life, but produce wider kerfs (cuts.)
4. Use a current level setting that is adequate to
produce an acceptable cut at maximum travel
speed. Operating at a current level that
exceeds the requirements needed to cut the
metal results in poor cutting quality and
machine operation.
5. Cut thin gage sections of aluminum, copper,
and other non-ferrous metals using a higher
current range. If acceptable results are not
obtained, use the procedures listed under
Cutting Thick Sections of Metal.
