SECTION 3
CAUTION: Do not depress the torch switch unless the
torch nozzle is touching or within 0.020-in.
(less than 1/32-in.) of the workpiece.
CAUTION: Locate the console at least 10-ft. from the
cutting work area. Chips and hot slag from
the cutting operation can damage the con-
sole.
After placing the primary (wall) switch to the ON position
TOO FAST TOO SLOW
Fig. 3-3 - Effect of Cutting Speed
and making control and air pressure adjustments as
described above, proceed as follows:
1. Touch the tip of the torch to the workpiece (or within
0.020-in. of the workpiece) holding the torch at about
15- 30° angle to avoid damaging the tip.

NOTE: The speeds given here are typical for best quality cuts. Your actual
speeds may vary depending on material composition, surface condi-
tion, 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 aluminum.
