6. Air Filter Assembly
NOTES
1. The gas input connection should be checked for leaks periodically, especially if the machine is moved.
2. Never operate welder on a generator that is not certified by its manufacturer to be "clean" power, which is less than 10% total harmonic distortion. Less than
5% is preferred. Operating the unit on square wave output or modified sine wave generator is strictly prohibited. Contact the manufacturer of the genera-
tor for this information. Everlast does not have an "approved" list of generators. But, if the generator is not listed as clean power by its manufacturer,
then operation is prohibited. Generators that do not at least meet the operating input requirements of the plasma cutter are also forbidden to be used
with the plasma cutter. Surge amp capability of the generator should equal or exceed the maximum inrush demand of the welder. But the surge capabil-
ity should not be used as the only factor. The regular, running output of the generator should match or exceed the running or "rated" demand of the
welder. Any damage done by operating the welder on a generator not specified by its manufacturer to be "clean", will not be covered under warranty.
This also includes suspect power sources where voltage is below 208 V and above 250 V. For 120V use, it should be within 110-130 V.
PARAMETERS
On/Off
The breaker switch has 2 poles. It serves as the On/Off switch for the welder. Always
turn the welder on and off by the switch first before using any disconnect. The Water
cooler outlet on the rear remains live after the switch is turned off.
120/240 V
The unit is prewired with a standard NEMA 6-50 plug. This is the standard plug for
1 phase, 50/60 Hz.
welders in the US and Canada. Other countries vary plug configuration as well as input.
As a dual voltage unit, when used with 120V supply connect the pigtail adapter to
reduce the input. When using on 120V, make sure the breaker and wiring is sized
properly for use or damage to the machine can result. Consult licensed electrician
before operating on 120V to confirm wiring and breaker suitability.
1/4-5/16"
The unit is supplied with tubing which connect this fitting to the air filter. The push to
connect design allows easy connection of the Cutter. Cut the tubing squarely before
installation to reduce the chance of leaking. If you suspect leaking, test the connection
with a solution of mild soapy water. If bubbles are seen, disconnect the tubing by
sliding the plastic collar on the fitting that surrounds the tube and remove the tube. (A
small bladed screw driver may be used to gently push the collar back if needed. Do not
use a lot of pressure. Once the tubing is installed, it will be held firmly until the collar
releases. Do not jerk the tubing.) Then cut the edges so the shoulder is cut fully per-
pendicular. Reinstall the tubing.
N/A
Normally this circuit is not required with the blow back start design. However, a small
amount of HF energy may still be emitted. If electronic interference is observed, this
bolt should be grounded directly to an outside source. All metal parts inside the build-
ing should be grounded as well, including pipes, tables, and even metal siding. HF
energy has been known to bleed back into the power grid and disrupt electronic devic-
es further down the grid. It is recommended that a small, separate ground wire
(minimum 14 gauge) be attached at this point while in use.
The filter helps remove fine particulates and large drops of water. A separate air dryer
must be installed inline to prevent rapid torch and consumable wear (Customer sup-
plied). The filter assembly is not designed to remove moisture from the air, only large
drops of water that may be created in the coupling and uncoupling process. Everlast
does not warranty damage caused to torches or consumables by moisture. Residual
moisture in the line also can contaminate the system, causing problems while TIG
welding. The number one issue experienced with Plasma cutting, that causes many
different symptoms, is the presence of moisture in the air line.
