CAUTION: Locate the console at least 10-ft. from the
cutting work area. Chips and hot slag
from the cutting operation can damage
the console.
After placing the primary (wall) switch to the ON position
and making control and air pressure adjustments as
described above, proceed as follows:
1. Touch the tip of the torch to the workpiece holding the
torch at about 15- 30
°
angle to avoid damaging the tip.
2. Depress the torch switch. (Air and high frequency
should energize.)
3. Two seconds after depressing torch switch, the plasma
arc will start cutting.
4. After starting the cut, bring the torch to an upright
position and proceed to cut by dragging the torch
along the workpiece. It may be necessary to cut
with a tip-to-work (standoff) distance of up to 1/16"
due to various material surface conditions.

5. When ending a cut, the torch switch should be released
to minimize double-arcing which can damage the tip.
This is to prevent high frequency from reigniting after
cutting arc extinguishes.
6. In the postflow mode, the arc can be restarted immedi-
ately by depressing the torch switch. The two second
preflow will automatically cancel.
