7. Adjust the air pressure from the Control Filter Knob on the back panel.
Caution: Verify that no wires, cables, or other obstructions are below the cutting area.
8. Place the Torch Head on the metal to be cut and press the Start button on the Torch
handle.
Start to cut slowly, then increase the speed to obtain the desired cut quality. Regulate
the speed to obtain a good cut. See illustration “A” below. Air plasma will create a
straight arc with stainless steel or aluminum, or a 5” arc with softer steel. The arc varies
depending on speed, material, and thickness.
In some cutting operations, it may be necessary to start the cut from a point away from
the edge. See illustration “B” above. The backfire from this operation could shorten the
life of the torch components, so it is recommended to do this cut as fast as possible.
Slightly incline the Torch so that the backfire particles are blown away by the nozzle
(and by the operator), instead of bouncing back into the Torch. Clean away slag and
incrustations from the Torch Head. Spraying or immersing the Torch Head in an anti-
slag substance, minimizes the quantity of incrustation that would stick to it.
9. When the cutting process is complete, release the Start button on the Torch handle,
place the Torch handle in a safe place, and wait 5 minutes before turning the On/Off
switch to “O” to allow proper cooling. The pilot arc is automatic, not manually
controlled. Handle the torch components with care and protect them from damage.
10. Unplug the line cord from the electrical outlet.
