POWERPRO FEATURES
PARAMETERS PURPOSE
1. Amp Display
N/A
Indicates amperage while cutting. While adjusting the amperage with the torch switch con-
nected relays selected amperage. When pilot arc is engaged, it is normal for the amps to drop
on the display. Typical readout while pilot arc is engaged is <30 amps.
2. On/Temp/ Duty Cycle/ OK
to Cut
On/Off
On indicator should always be on while the unit is plugged in and the power switch is switched
on. The Duty Cycle/ Over Current light is a dual colored LED. The color will appear red/amber if
duty cycle is reached and welding/cutting will be interrupted. The unit should automatically
reset if this light comes on. If the unit does not reset, manually cycle the power switch after 10
minutes. Do not turn off the unit until it has had sufficient time to cool. If it appears Green,
then it is likely an overcurrent situation has occurred. Cycle the power switch to reset the ma-
chine. The light should go off. If it does not, and will not weld, contact Everlast. The OK to cut
light remains amber colored (color may vary) while the air pressure is above the minimum
threshold pressure threshold. This is not a warning light, but rather it gives the operator assur-
ance at a glance that the pressure is within tolerable limits to prevent torch damage. Addition-
ally when the pressure falls below this threshold (approx. 35 psi) the unit will stop cutting auto-
matically. Cutting will resume once the pressure rises above the minimum threshold. If the
light is on, however, it does not indicate the pressure is at optimal levels. Further tuning of the
air pressure may be needed. See below.
3. Amp Control
N/A
Controls amperage output.
4. CNC/Manual Switch
This switch allows the user to select the torch operation for a simple remote trigger with a semi
automatic CNC device such as a track torch. It also allows manual, press and hold cutting when
set to “manual”. When selected for CNC, the operation of the torch only requires a simple
touch of the trigger or remote device to activate the arc. Once activated the switch can be
released and the unit will continue cutting. To stop, simply press and release the switch again.
This feature is tied only to the front pins on the central connector only and does not operate in
conjunction with the CNC port on the rear. These two functions are separate, with different
intended forms of operation. For manual cutting, simply press and hold the trigger. For safest
use, do not operate the torch manually with the switch in the CNC mode. The torch will stay
ignited until the trigger is cycled again. This can cause confusion if in an emergency situation.
5. Post Flow Control
0-60 Seconds
(approximate)
Sets the post flow time of the air. Time is approximate only and can vary somewhat from the
maximum limit posted from unit to unit. Consider the maximum setting mark a reference guide
only. Use approximately 1-3 seconds of air flow for every 10 amps. More for extended cuts.
6. Constant Flow/Timed Flow
N/A
When set to constant flow, the air will continue to flow indefinitely to allow the air pressure to
be set, or the flow gauge to be installed to allow the flow/pressure to be adjusted to the opti-
mum level with the flow tube. This prevents accidental arc initiation while the air pressure is
being set. The “Timed flow” is the normal position used for cutting . Cutting should not be
attempted in the constant flow position.
7. Work Piece
25 series
Location of the positive terminal connection for the work clamp cable. DINSE-style connector.
8. Fuse
This fuse protects the operation of the pilot arc and circuits of the machine should there be an
overcurrent or feedback onto the system. If the display ceases to operate or pilot arc quits
check the fuse. Extra fuses are provided in the accessories kit. If no fuse is available, a standard
glass type automotive fuse will work. Be sure to match the amperage of the fuse. Do not
exceed the amp rating of the fuse or damage may result to the machine.
9. Central Connector
9 mm
This serves as a unified, quick connection for the torch. The Central connector is a universal
style connection and is available as a retrofit on many different brands through Trafimet. The
connector carries power and the torch switch signal.
10. Air Pressure Adjustment
90 psi supply
pressure max.
70-75 psi
operating
pressure
To increase pressure, pull knob out until it clicks (about 1/4”). Then, rotate knob clockwise to
increase pressure, counterclockwise to decrease pressure. Press in to lock. Do not supply the
unit with MORE than 90 psi from the compressor. Do not operate the torch with more than 75
psi for optimum results. The torch manufacturer recommends a pressure setting of 72-73 psi (5
bar) Instead of lowering pressure to use less amperage, change nozzle to a smaller orifice size.
However for some situations lower air pressure may yield satisfactory cuts, down to 65 psi
. Do
not lower air pressure just to make low amp cuts. Use a nozzle with a smaller orifice.
14. Air Pressure Gauge.
90 psi max
supply
65-75 oper-
ating
Used to measure air supply pressure.. Supply pressure should not exceed 90 psi. Adjust oper-
ating pressure while air is flowing with gauge provided, or adjust to 72 psi and increase or de-
crease pressure from there to achieve optimum cutting results. If air pressure drops more than
10 psi from compressor to unit air pressure gauge, check for internal kinks or leaks in tubing.
