1.1
General Description, Purpose and Features.
The
PowerMTS 160 and 200S, are compact lightweight CV/
CC welders capable of handling most jobsite duties and
portable repairs. Operating on 1 phase 220-240V
50/60Hz, the units are designed to strike an excellent
balance between versatility and performance. The fol-
lowing processes are included on the PowerMTS series.
1)
GMAW
(MIG) offers wave form control which re-
sults in a smooth, stable arc . Digital controlled
MIG components precisely control functions and
give real-time feed back about the welding output
parameters. The 200S also utilizes fully digital syn-
ergic technology with a manual override function
for standard operation. (see below). MTS 160 has
manual function MIG with no synergic capability.
2)
GTAW
(TIG) offers advanced lift start DC TIG opera-
tion includes a standard gas valve torch. (Series 17
compatible).
Note:
DC Lift start is actuated by the
remote contactor built into the handle (included).
The TIG torch is not live until the contactor switch is
depressed. The user has a choice of either 2T or 4T
operation while welding.
3)
SMAW
(Stick) delivers smooth spatter free welds.
Arc force control increases performance, and im-
proves out of position welding characteristics.
Smooth spatter free welds are easily obtained on
ER 7018, 309L, and many specialty rods.
1.2
Basic Design and Construction.
The PowerMTS se-
ries units uses advanced Pulse Width Modulation cou-
pled with IGBT module construction to produce a stable
arc without consuming large amounts of power attribut-
ed to standard transformer welders. Inverter frequency
is approximately 40KHz. Welding power is generated as
follows
(See page 11 for flow diagram)
: Single phase
220V AC (nominal) power is fed into the welder, where
it is rectified in to 350V DC. After it passes through an
intermediate transformer, reducing the voltage, power
is fed to the IGBT based inverter where it is converted
to converted to AC power cycling around 40Khz. Next
power and passed back through fast recovery diodes to
rectify the power back to DC while being filtered
through an inductor circuit. The circuit then uses cur-
rent/voltage feedback sensing technology through the
means of its CPU control board to maintain stable TIG/
Stick performance, ensuring stable MIG performance as
well. Welding parameters can be infinitely and continu-
ously adjusted while the unit is in operation, offering
instant welding response.
1.3
Installation and Wiring.
The basic construction of
the PowerMTS is rugged and durable, and is considered
ideal for circumstances where multiple welders may be
required, but not available. Critical components are
protected by coatings to make the welder environmen-
tally resistant with a water ingress rating of IP23S,
among the highest in the industry. However, some
care and common sense should be taken to make sure
that the welder offers the safest and best performance.
Please note the following items regarding safe opera-
tion:
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.
VRD technology helps to reduce the risk of electro-
cution from high OCV, but does not necessarily
eliminate the risk, especially while welding.
2) Do not use the welder in extreme 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 corrosion and oxidation can result in
an unstable arc and excessive heat build-up.
Match the correct colored wires located on page 15
with the wires found on your unit so that the unit can
be properly connected to the power supply. Be sure to
make a secure ground connection to the plug and iden-
tify the correct 115 V power legs on the power input
side, commonly referred to as “hot” wires. A neutral
wire is not required, and should not be used. If a 4th
wire on the input side is found in a single phase system,
it is probably a neutral. The circuit should be rewired if
this neutral is present so that only two “hot” wires and
one ground wire is present. Everlast strongly recom-
mends using the NEMA 6-50, a three wire 50 amp plug
and receptacle, available at almost all hardware stores.
The NEMA 6-50 P/R is the industry standard plug /
receptacle for welders. Consult local codes and li-
censed electricians should any doubts or problems
arise. If doubts remain, contact Everlast for more infor-
mation. Wiring the welder incorrectly can result in fail-
ure/damage to the welder.
Introduction and Specifications
Section 1
NOTE:
DC TIG is not generally considered capable
of welding Aluminum. The MTS units are DC only
and do not have AC capability.
Aluminum welding may be performed with
the MIG process, with Argon gas, and a suitable gun
liner. Recommended wire size for welding alumi-
num is .040”. 50XX series wire is also recommend-
ed. 40XX series may have difficulty feeding.
