PARAMETERS
PURPOSE
1. Amp Display
20-60 (60S)
20-70 (70S)
20-80 (80S)
Displays selected amperage until cut starts. Once cut starts, then amps display dynamically by dis-
playing the actual output amps while cutting. While Pilot arc is engaged or when cut starts, the
amps will drop to 20-30 amps until continuity is sensed and cutting arc takes over and the pilot arc
disengages. Pilot arc is not designed to Cut. It should only be used to scour the surface, to gain
continuity for the cutting arc.
2. Air Pressure OK to Cut LED
On/Off
This light should remain on as long as there is sufficient cutting pressure to protect the torch from
melting. Once the air pressure drops below the minimum threshold of approximately 35 psi, the
light will go out, indicating the pressure is too low. If the light goes out the unit will prevent the
torch from being activated and there will be no power to the torch and the unit will not cut until the
minimum air pressure is satisfied.
3. Air Pressure Gauge.
0-150 psi
The gauge registers up to 150 psi, but air pressure should never be set above 85 psi. Air pressure to
the torch should be set at 70-75 psi. Ideal rated pressure by Trafimet is set at 72.5 psi.
4. Amp Control
Infinite
Adjusts and selects desired operating amperage.
5. Central Torch Connector
N/A
The central torch connector is an all-in-one connector. It is a universal connector and is available as
part of the Trafimet OEM Torch connection. It greatly simplifies torch connection. When installing
the connector, line up the tab on the male piece with the key hole slot on connector on the machine
side. Insert the coupling fully and then tighten the collar nut on the torch fitting hand tight.
6. Fuse
2 A
This fuses the operating and display circuit of the unit so that it is protected from power surges and
overloads. If the unit ceases to operate or the display will not work, check the fuse and replace it.
This is a standard glass type automotive fuse which can be sourced locally. Do not use a higher
rating than what the old fuse is rated for or damage can occur.
7. Work Piece Connector
N/A
The work lead (sometimes referred to as “ground”) is used to complete the circuit. The torch pilot
arc may be active, but the unit will not actually cut if the work lead is not connected to the work
piece. If an arc is present but the unit will not actively cut or is very slow or poor cutting any materi-
al, check and make sure work lead is connected and is connected to a clean spot on the work.
8. Air Post Flow
0-60
Select a post flow time that is appropriate to cool the torch and the consumables. Post flow time will
depend upon the amps and length/severity of use. A post flow time of 3-5 seconds post flow for
every 10 amps is suggested.
9. 2T/4T Trigger lock
2T/4T
2T is considered the normal method of operation for this torch. To operate, simply press and hold
the switch and cut normally. Release the switch when the cut is finished The 4 T setting allows the
torch to be locked on during use. To use, place the switch in the 4T position. Then simply press and
hold the trigger to start the arc. Release the trigger to continue cutting. Once the arc is ready to be
terminated slowly press and release the switch again. Caution: When this feature can leave the
torch activated if the torch is withdrawn from the cutting area .
10. Pilot Arc Function
3 sec/Normal
This allows the user to select for the best operation of the pilot arc to save consumables. The 3
second pilot arc engages the pilot arc for 2-3 seconds only before it shuts the arc off. To get the pilot
arc to reactivate, the trigger will have to be pressed again. Normal mode allows the pilot arc to
remain on and engage and disengage as needed.
11. Air Flow Function
Test/Normal
Select “Test” to set air flow/air pressure for the torch. The operating pressure should always be set
while this is in Test since it does not ignite the pilot arc. This allows the air to flow constantly until
the switch is placed back into the normal, timed mode. To set the air pressure, turn the torch until
the nozzle is facing up, then place the flow tube (clear plastic tube with ball in it) over the nozzle.
Select “Test” on the machine. With the air flowing, adjust the air pressure/flow up or down until
the ball is floating in the sight window of the flow tube. If no flow tube is present or provided with
your unit, then simply set the air pressure while “Test” is selected until it is somewhere between 70-
75 psi. Pressure over or under this can result in an unstable arc.
12. On/ Temp/ Over Current
On or Off
These indicate the status of the machine and indicate if any fault is present. If duty cycle is exceed-
ed, the Duty Cycle light will come on and cutting will be interrupted, but the unit will continue to run
and the fan will cool. Once the light goes off cutting may resume. After 5-10 minutes, if the light
does not go off and cutting is still prevented, the cycle the machine off and then back on. If the Over
Current light is on, recheck all wiring and connections and make sure the correct wire size and wiring
has been used. Purposefully creating too long of an arc may also cause this or it could be a side-
effect of hitting the duty cycle limit of the machine. Cycle the machine on and off. If the light clears
and cutting resumes, the fault has been cleared. If the unit will not work and/or the light remains on,
contact Everlast Tech Support.
