3.3 CUTTING OPERATION (continued)
4. With the pilot arc on the main cutting arc is established
as soon as the torch tip is brought within 1/8 - 3/8 in
(3 - 10 mm) of the workpiece.
The NORMAL/DELAYED RESTART switch (SW1) is
located on the control logic PC board (refer to Figure 5-5,
page 45). The switch is factory set to NORMAL (open)
position. If the cutting arc is interrupted and the torch
switch is still pressed (as when cutting expanded metal)
the pilot arc will automatically restart. If the switch is set
to DELAYED (closed) position, there is always a two
second pre-flow delay before restarting.
Releasing the torch control switch will shut off either the
pilot or main arc (depending on mode of operation).
5. Cut with the torch tip 1/8 - 3/8 in (3 - 10 mm) from the
work. The torch should be held perpendicular to the
workpiece while cutting.
