Plasma Function And Operation - Everlast PowerUltra 206Pi Setup And User Manual

Section 3
Helpful Hint: You can cut any thickness within the plasma cutter's range with full amperage. However, a difference in kerf and fineness of
cut may be observed. To establish a basic cutting guide for the best cut, set the unit for 20 amps to cut up to 1/8" steel thickness. For every
additional 1/8" of cut thickness encountered, add 10 amps for good cutting speed. Although the unit is capable of cutting metal 3/4" thick or
greater, this is only a severance cut and not quality or production cut. This unit is best for regularly cutting metals of 1/2" or less. Match
nozzle orifice size to the amperage being cut for best results. Significantly lowering the air pressure while using a larger diameter orifice will
only result in cutting instability. Use a .6mm nozzle for 20-25 amps, .8mm for 20-35amps, .9mm for 35-50 amps. Different sized consuma-
bles are available from Everlast and many online or local sources. There is some overlap in nozzle cutting capacity, but minor fine-tuning of
air pressure may help improve cut results. However, do not exceed 80 psi cutting pressure, and do not lower cutting pressure below 60 psi.
0°-15° EDGE START
1/16"
Edge Starts are the best type of start if possible
to promote consumable and torch life. This re-
duces blow back of molten material and allows a
smooth gradual start of the cut.
1. Line up the hole on the tip of the electrode
on the edge of the cut. Hold torch perpen-
dicular to the cut initially, about 1/16" off
the metal.
2. Once the arc starts, wait for the arc to pene-
trate all the way through the metal.
3. As the torch penetrates its flame all the way
through the metal, tilt the torch so there is a
slight lead in the flame if metal is thin. If it is
thick, keep holding torch in a nearly vertical
position.
4. Begin moving the torch in the direction of
the cut. Maintain 1/16" standoff height.
5. Move the torch fast enough so the sparks
and flame trail from the bottom edge at an
angle of no more than 30° and no less than
10° from perpendicular to the metal. Excess
angle of sparks/flame indicate too fast of
travel speed or practical cut capacity has
been reached. Little or no angle indicates
too slow of travel speed.
IMPORTANT: If you use a standoff guide with the torch, it must be adjusted or bent to provide no more than 1/8" standoff, less if possible.
Long standoff heights reduce cut capacity and quality. It also promotes rapid consumable wear and can prevent the pilot arc from transferring.

Basic theory and function
1
40°-60°
Piercing starts often result in rapid consumable
wear and excess blow back of molten metal de-
posited onto torch and consumables. This
should be done only as necessary.
1. Tilt the torch in the direction of travel or
toward the side of the metal to be discarded
or wasted at a 40° to 60° angle. Slide the yel-
low safety lock and squeeze the trigger.
2. Once the arc starts, wait for the arc to trans-
fer from pilot arc to the cutting arc.
3. As the torch penetrates it flame at an angle
rotate the torch slowly to the vertical posi-
tion, as the arc penetrates the metal. Tilt the
torch from 0°-15° for thin metal cuts, or hold
it nearly perpendicular for thicker metal cuts.
4. Begin moving the torch in the direction of the
cut. Maintain 1/16" standoff height.
5. Move the torch fast enough so the sparks
and flame trail from the bottom edge at an
angle of no more than 30° and no less than
10° from perpendicular to the metal. Excess
angle of sparks/flame indicate too fast of
travel speed or practical cut capacity has
been reached. Little or no angle indicates
too slow of travel speed.
