2.
Grate Cutting
- For rapid restarts, such as grate or heavy mesh cutting,
do not release the torch switch. This avoids the 2 second pref-flow portion of the
cutting cycle.
3.
Edge Starting – For edge starts, hold the torch perpendicular to the work
piece with the front of the tip near (not touching) the edge of the work piece at the
point where the cut is to start. When starting at the edge of the plate, do not pause
at the edge and force the arc to ‘reach’ for the edge of the metal.
Note: The speeds given here are typical for best quality cuts. Your actual speeds may vary
depending on material composition, surface condition, operator technique, etc. If cutting
speed is too fast, you may lose the cut. With slower speeds excessive dross may
accumulate. If speed is too slow, the arc may extinguish. Air cutting typically produces a
rough face on stainless steel and aluminium.
Establish the Cutting Arc as Quickly as Possible.
4.
Drag Cutting - Position torch tip slightly above work piece, press torch switch and
lower torch tip forward work piece until contact is made and cutting arc is
established. After cutting arc is established, move the torch in the desired direction
keeping the torch tip slightly angled, maintaining contact with the work piece. Avoid
moving too fast as would be indicated by sparks radiating from the topside of the
work piece. Move the torch just fast enough to maintain sparks concentration at the
underside of the work piece and making sure the material is completely cut through
