seconds to allow the torch to cool down.
It is best not to turn the machine off until this cool-
down period is complete.
• Should you need to make holes or begin cutting from
the center of the workpiece, you must hold the torch at
an angle and slowly straighten it so that the nozzle does
not spray molten metal (see fig. 2). This must be done
when making holes in pieces more than .118" thick (12
gauge=1.05").
• If you need to cut several layers of metal, as are normal-
ly used in auto body work, adjust the cutting current to
the minimum values
Turn the machine off when the task is completed.

• The electrode must be re-

no longer smooth and the
cutting capacity is dimin-
ished.
• The swirl ring must be re-
