Lincoln Electric IM618 POWER WAVE 455STT - Manual (Page 15)

B-3 OPERATION B-3
GENERAL DESCRIPTION
The POWER WAVE 455 STT is a high performance,
digitally controlled inverter welding power source
capable of complex, high-speed waveform control.
Properly equipped, it can support the GMAW, GMAW-
P, FCAW, SMAW, GTAW, CAC-A and STT process-
es.
RECOMMENDED PROCESSES AND
EQUIPMENT
RECOMMENDED PROCESSES
The Power Wave can be set up in a number of config-
urations, some requiring optional equipment. Each
machine is factory preprogrammed with multiple weld-
ing procedures, typically including GMAW, GMAW-P,
FCAW, SMAW, GTAW and CAC-A, for a variety of
materials, including mild steel, stainless steel, cored
wires, and aluminum. Additionally, it supports the
Surface Tension transfer process (STT) for mild steel
and stainless steel.
RECOMMENDED EQUIPMENT
The POWER WAVE 455 STT must be used with the
Power Feed family of wire feeders. These feeders are
required to access and make use of the many of the
welding features contained in the POWER WAVE 455
STT.
DESIGN FEATURES AND ADVANTAGES
A unique feature of the Power Wave is the ability to
function without any controls, when used with Power
Feed wire feeders. All power source control informa-
tion comes to the Power Wave from a Power Feed
wire feeder.
The following chart lists the power source parameters
that can be changed from the Power Feed wire feed-
er, and gives examples of each. (Optional equipment
may be required to access some of the following para-
meters.)
ADDITIONAL DESIGN FEATURES AND
ADVANTAGES
• Designed to NEMA EW-1, IEC 974-1 and CE
Standards.
• Qualifies for “S” mark on nameplate, which means it
can be used in areas where there is increased risk
of electric shock.
• Multiple process output ranges: 5 - 570 amps.
• Easy access for input connections. Connections
are simple strip and clamp (no lugs required).
• F.A.N. (fan as needed). Cooling fan runs only when
necessary.
• Modular construction for easy servicing.
• Thermostatically protected.
• Electronic over current protection.
• Input over voltage protection.
• Utilizes digital signal processing and microprocessor
control.
• Simple, reliable input voltage change over.
• All system components communicate and transfer
information.
• Auto device recognition simplifies accessory cable
connections.
