Assembly
NOTE: Never operate this unit on a generator that is not certified by its manufacturer to be "clean" power, which is typically less than 5% Total Harmonic Distorition (THD). Operating the unit on
square wave output or modified sine wave generator is strictly prohibited. Contact the manufacturer of the generator for this information. Everlast does not have an "approved" list of genera-
tors. 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 welder are
also not to be used with this unit. Surge amp capability of the generator should equal or exceed the maximum inrush demand of the welder (see specifications) But the surge capability 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.
PARAMETERS
On/Off The breaker switch serves as the On/Off switch for the welder. Always turn the welder
on and off by the power switch first before using any main disconnect switch.
120/240 V The PowerUltra 206Pi is fitted with a standard NEMA 6-50 plug. This is the industry-wide
1 phase, 50/60 Hz standard plug for welders in the US and Canada. Other countries vary plug configuration
NEMA 6-50P. as well as input. When 120V use is desired connect the pigtail, 240V to 120V adapter to
reduce the input. No rewiring is required as long as 120V input power supply conforms to
the local and national codes, which includes using proper wire gauge and breaker sizing.
Always consult a licensed electrician. Do not rewire the unit. When using on 120V,
make sure the breaker and wiring is sized properly for use or damage to the machine and/
or wiring can result. NOTE: Operating on maximum output on 120V is not recommended
for long periods of time on standard household wiring (usually wired as 15 to 20 amps
only). A 120V, use 30 amp breaker or fuse (designated as slow trip breaker or slow
blow fuse) along with heavier than standard gauge wiring, will be required to operate for
sustained periods of time on 120V while welding or using at maximum output. Consult a
licensed electrician before operating on 120V to confirm wiring and breaker suitability for
this type application.
5/8" CGA This is connection point for the TIG shielding gas and air supply for the plasma cutter. The
unit is supplied with a 5/8 CGA fitting to connect directly to the argon regulator and to the
unit's air supply filter. This fitting is the standard shielding gas fitting found on most Ar-
gon/inert gas regulators in North America. Make sure that all connections are tight and
secure. Do not use thread tape or other compounds on the compression fittings. If you
suspect leaking, test the connection with a solution of mild soapy water. If bubbles are
seen, retighten or reinstall the tubing. While changing processes, the fittings must be
swapped. Do not run the Argon gas through the air regulator/filter. As the unit comes
equipped, the unit cannot remain connected to both the air supply and the argon supply
at the same time. However, a T-fitting or Y-fitting may be placed inline at the connection
to leave both argon and air hooked up without having to swap out the lines (customer
supplied). Running humid air through the TIG torch (as a result of poor maintenance of
the plasma cutting aspect of the unit) will create problems. Be sure to use the air dryer,
and other items recommended. Running Argon through the plasma cutting filter and
tubing is a prime way to introduce unwanted moisture to the TIG torch.
N/A HF energy generated by the unit's components can affect surrounding electronic equip-
ment. If the operating environment includes electronic equipment, this connection can
serve as a direct path to an outdoor grounded metal rod that is isolated from the main
electrical circuit to help bleed off excess HF circuit. All metal parts inside the building
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 devices further
down the grid. If the point gap becomes out of adjustment, more HF energy may build
up, or even jump across circuitry within the welder. It is recommended that a small,
separate ground wire (minimum 14 gauge) be attached at this point while in use.
90 psi maximum The air filter/regulator filters fine particulates and large drops of water. The filter is not
Supply pressure. designed to have argon flowing through it. A separate air dryer must be installed inline to
70-75 PSI oper- prevent rapid torch and consumable wear (Customer supplied). The filter assembly is not
ating pressure designed to remove all moisture from the air. Everlast does not warranty damage caused
while cutting to torches or consumables by moisture. Residual moisture in the line also can contami-
nate the system, causing problems while TIG welding. The number one issue experienced
with Plasma cutting, (causing a wide variety of symptoms, including rapid wear and unsta-
ble arc) is the presence of moisture in the air line. To adjust the air pressure for cutting,
simply pull the knob up until it clicks and rotate it clockwise to increase the pressure, and
rotate it counter clockwise to decrease the pressure. To adjust the air pressure correctly,
adjust it while the air is flowing in the purge mode. If a flow tube for the torch is provided,
adjust it so the ball floats in the window as depicted in the torch manual. After installing
flow tube (if supplied) make adjustments to the air pressure while it is flowing. Adjust
pressure to 70-75 PSI if no flow tube is provided while the purge function is on.
