POWER WAVE ® STT ® MODULE (CE)

SAFETY PRECAUTIONS

Read this entire section of operating instructions before
operating the machine.
WARNING
ELECTRIC SHOCK can kill.
• Disconnect input power before servicing.
• Do not operate with covers removed.
• Do not touch electrically live parts.
• Only qualified persons should install, use or
service this equipment.

POWER-UP SEQUENCE

The POWER WAVE ® STT ® MODULE (CE) will be powered up at the
same time as the power source. The status light will blink green for
about a minute while the system is configuring. After this time, the
status lights will turn a steady green indicating the machine is
ready.
The fan in the POWER WAVE ® STT
the power source fan is activated.

DUTY CYCLE

The POWER WAVE ® STT ® MODULE (CE) is rated at 450 amps at a
100% duty cycle. It is further rated to support 500 amps at a 60%
duty cycle and 550 amps at a 40% duty cycle. The duty cycle is
based on a ten-minute period. A 60% duty cycle represents 6
minutes of welding and 4 minutes of idling in a ten-minute period.
Note:
The POWER WAVE ® STT ® MODULE (CE) is capable of withstanding
a peak output current of 750 amps. The allowable maximum
average output current is time dependant, and ultimately limited
by the host power source.

COMMON WELDING PROCEDURES

MAKING A WELD
Choose the electrode material, electrode size, shielding gas, and
process (GMAW, GMAW-P, GMAW STT
material to be welded.
Select the weld mode that best matches the desired welding
process. The standard weld set shipped with the host power source
encompasses a wide range of common processes that will meet
most needs. If the STT ® modes are not available, or if a special weld
mode is desired, visit www.powerwavesoftware.com or contact the
local Lincoln Electric sales representative.
® MODULE (CE) will run only when
® etc.) appropriate for the
To make a weld, the power source needs to know the desired
welding parameters. Set the parameters on the user interface
typically located on the wire feeder. The user interface sends the
parameters (arc voltage, wire feed speed, UltimArc
the power source via the ArcLink
the control cables. The power source controls the POWER WAVE
STT ® MODULE (CE) based on the selected weld mode.

process supported by the host power source including, but not
limited to SMAW, GMAW, GMAW-P, GMAW-STT
PROCESS LIMITATIONS
The POWER WAVE ® STT ® MODULE (CE) is unaffected by the voltage
at the load, and therefore processes are only limited by the current
and duty cycle ratings listed in the specifications for the product.
The POWER WAVE ® STT ® MODULE (CE) is designed to protect itself
from the excessive transient voltages associated with highly
inductive weld circuits. These high inductance circuits may result in
unsatisfactory performance, but will not damage the module.
Although the STT ® Module can be configured to support negative
electrode polarity processes, such as Innershield, the STT
must be configured to use positive electrode polarity.
