Basic Design and Construction. This multi - process
welder features an intuitive control panel and couples it
with digitally controlled IGBT inverter design that pro-
duces a stable arc while conserving energy. Everlast
utilizes quality components from US, European, and
Asian based companies to ensure reliability and parts
commonality. Major control components are of a mod-
ular, plug
- and - play design which allows rapid diagnosis
and repair of the welder. Welding parameters can be
infinitely and continuously adjusted throughout the
range, offering instant welding response for maximum
control.
Installation. The basic construction of the PowerMTS
221STi is rugged and durable. It is considered ideal for
circumstances where portability is of concern. Critical
components are protected by coatings to make the
welder environmentally resistant and has a water in-
gress rating of IP21S, (the standard in the welding indus-
try to protect from vertically dripping water). However,
some common
- sense care should be exercised to make
sure that the welder offers the safest and best perfor-
mance. Please note the following items regarding safe
and proper operations to ensure best service and re-
sults while welding:
1) Do not use the welder in damp or wet areas. Per-
spiration and other forms of water in contact with
the body can increase the risk of electrocution.
2) Do not use the welder in extremely corrosive envi-
ronments. To maintain optimum power transfer,
check main connections, clamps and cables fre-
quently to ensure that components are not corrod-
ed. Excessive dirt, corrosion and oxidation can re-
sult in an unstable arc and excessive heat build
- up.
If the work clamp becomes corroded or damaged,
be sure to replace it with a heavy
- duty work clamp
rated for at least 300 amps. If your work clamp
appears to become extremely hot while welding,
and all connections are clean and secure, replace
the work clamp. Unstable arcs and hard starting,
especially in MIG mode are often the result of poor
work clamp condition or connection.
3) Store the welder covered with a moisture and fire
resistant material.
4) If used on a mobile cart, strap or fix the welder to
the cart so that accidental overturn is not likely.
Duty Cycle/Overcurrent/Under Voltage/Overvoltage
Warnings.
Thanks to a quad cooling fan design, the
PowerMTS 221STi has a duty cycle rating of 30% at 200
Amps while welding in MIG. 35% while welding in TIG
mode at 200 Amps and a rating of 60%@ 160 Amps
while welding in stick mode(240V). The duty cycle
rating is the amount of time (expressed as a percent-
age) out of 10 minutes the unit can weld without a rest.
For MIG, the unit is capable of welding 3 minutes out of
every 10 minutes at the maximum output of 200 Amps.
For the balance of the 10 minute period, the unit
should be allowed to rest and cool while running. This
rating is based off a 40° C maximum temperature. If
the unit
’ s duty cycle has been exceeded, the Stop LED
will come on and unit will cease welding output. An
error code of
“ E04 ” will be displayed If a duty cycle
event has occurred. Allow the unit to run and cool for
15 minutes. After 15 minutes of cooling the unit while
switched on without welding, cycle the power switch to
reset the unit if needed. In the event of an overcur-
rent, the welding output will cease and the
“ Stop ” LED
will come on and an error code of EO2 will be dis-
played. In duty cycle and overcurrent events, the wire
may continue to feed without output. Overcurrent
events can be caused by too low of supply voltage, run-
ning on undersized extension cords, too large of wire
diameter, too high of settings for wire diameter, too
high of input voltage, or internal or external electrical
fault. When an overcurrent has occurred, turn the ma-
chine off immediately, then check and remedy the fault
before cycling the welder back on. If the error does
not clear after cycling, cease operation and call Everlast
Technical Support.
Do not intentionally and repeated-
ly trigger the duty cycle limiter. Doing so repeatedly
will shorten the lifespan of the unit
’ s components.
Under or over voltages will also trigger the Stop LED.
The error code of E01 will be displayed. This is likely a
result of a poor power supply, a long extension cable,
or from running off of a generator that is malfunction-
ing.
Note: If a generator is going to be used with this
unit, please make sure that it is certified by it ’ s manu-
facturer to be “ clean power, ” which is normally stated
as less than 5% THD ( Total Harmonic Distortion). Ever-
last makes no recommendation or certification of any
generator
’ s suitability for use with our units. The cer-
tification or statement of assurance from the manu-
facturer of wattage and clean output capability is to
be obtained from the manufacturer of the generator.
For proper operation with a generator, make sure you
have at least a minimum 8,500 watts of surge capabil-
ity and 6500 watts of continuous rated output capabil-
ity. Any failure of the unit related to the unit running
on
“ dirty ” power or underrated wattage will not be
covered under the warranty. Unit failure or damage is
not always immediate or visible and can occur gradu-
ally over a long period of time.
