TORCH PART CONFIGURATIONS
There are different torch configurations depending on
the cutting or gouging application.
Standard Cutting Setup:
In the Standard Cutting configuration the nozzle is
designed not to touch the work piece. The advantage
of this cutting method is good visibility of the arc.
However it requires a steady hand to avoid touching
the nozzle to the work piece which will cause prema-
ture nozzle wear and a jagged cut. An optional drag
spacer can be attached to the retaining cap to main-
tain a consistent arc height.
Contact Cutting Setup:
Contact Cutting uses special expendable parts that
allow the torch to touch the work piece. The advan-
tage of contact cutting is that the torch can touch the
work piece, steadily dragging it across the surface.
The disadvantage of contact cutting is the plasma arc
is not as visible as with a standard torch set-up. Since
this machine cuts at 40 amps or less it uses the direct
contact torch configuration which allows a special noz-
zle to come in contact with the work piece.
