PURPOSE
N/A Indicates actual amp output while welding. While adjusting or while not welding, the func-
tion of the display changes to display the selected amperage.
On/Off The On LED should always be lit while the unit is plugged in and the power switch is
Over Temp switched on. If the Overcurrent LED is lit, turn the unit off and check for possible causes
(Duty Cycle) including undersized cables, poor connections and overheating cables. The Over Temp LED
Over Current indicates when the Duty cycle has been exceeded and overheated. If the Over Temp LED is
OK TO CUT lit, do not turn off the unit until it has had sufficient time to cool (10-15 minutes). Cycle the
(35-40PSI) power switch to reset the machine only after the machine has had time to cool. The duty
cycle and overcurrent warning lights should go off after cycling the power switch on the
machine. If it does not, contact Everlast. The OK-TO-CUT LED will be lit when the unit has
enough pressure to operate the plasma cutting torch safely. If this LED goes out, cutting will
not be possible as the unit will stop output when it senses low air pressure. This is a safety
feature designed to prevent torch and consumable damage should the air pressure drop
below the safe levels or the air hose is not connected. Keep in mind this does not monitor
ideal air pressure, and is only designed to prevent operation when the air pressure is not
connected or too low to operate. The minimum safe threshold for the OK-TO-CUT light to
come on and allow the unit to cut is approximately 35-40 psi.
0-10 Seconds While welding with the torch switch, this feature is used to set a Amperage ramp down time
during the final phase of the welding cycle, in either 2T or 4T mode. This has the same effect
as backing off the foot pedal to finish your weld. Use this period of time to fill your crater as
the puddle begins to cool. This will help prevent cracking in the crater. Set to 0 while the
foot pedal is connected, or a flare of the arc may be observed at the end of the cycle.
0-50 Seconds Sets the post-flow time of the shielding gas while welding in TIG mode. While in plasma (cut)
mode, it sets the post flow time of the air. Time is an approximation only and can vary a little
from the setting posted on the dial. The air or shielding gas may stop flowing before full
maximum time is reached. Consider the maximum setting mark a reference guide only. Post-
flow helps to deliver a better quality TIG weld by providing flow of shielding gas to the mol-
ten weld pool as it solidifies and cools after the arc has been terminated. It also cools and
protects the Tungsten and torch during this time as well. For plasma cutting it helps to cool
the torch down, extending consumable life. Use about .5 to 1 seconds worth of post flow
time for every 10 amps used to weld in TIG mode. Use a minimum of 2 seconds postflow
time for every 10 amps used in the plasma cutting mode.
N/A This switch determines which mode controls the unit, 2T, 4T or the pedal. Using either one
will determines how the unit behaves. When using the foot pedal, the unit must always be
in 2T to operate properly. The 2T feature, when used with the torch switch allows you to
press and hold the torch button to start the arc and continue to weld. Release the trigger to
stop the arc and begin post-flow mode. The 4T feature allows you to press down on the
switch to start the arc. After starting release the trigger and the unit will continue to weld
without further action on the trigger. To stop the arc, simply press and hold and the arc will
fully terminate when the switch is released. The post-flow will begin to flow.
N/A This switch selects processes. Do not switch this switch while welding or cutting, Do not
switch it with the wrong torch connected or immediate failure of the unit may result. Im-
proper polarity can contribute to torch failure as well. Make sure all connections are in-
stalled properly before cutting or welding.
Off, 1Hz, 25 Hz This unit is equipped with a easy to use pulse. With this feature, the operator may simply
choose from pre-programmed settings of Off, 1Hz, or 25Hz pulse. All other parameters are
preset including pulse amps and pulse time on and are optimized for a broad range of amp
settings. This pulse feature is intended to improve bead appearance and to help control
heat on thin metal to prevent burn through and heat wicking on edges. The 1Hz setting can
be used to help time the addition of filler metal during each pulse. It is slow enough to allow
the operator time to deposit one single "add" of filler metal in the puddle during the high
amperage stage of the pulse. With the 1Hz setting, the user should be able to use this to
create an evenly spaced, rippled bead appearance. The main goal of the 1Hz setting is to
help the operator to improve consistency while helping maintain heat control. At the 25 Hz
setting, average heat will be reduced and extra control will be achievable on thin metals that
are subject to warping and burn through, especially on edges and outside corners.
