INTERNAL CONTROLS DESCRIPTION
1. FUSE (F1): Primary circuit protection for auxiliary power
(10A/600V).
2. ROBOT POWER TERMINAL BLOCK (4TB): Power sup-
ply connection for Fanuc R30iA controller. Supplies pri-
mary power through the ON/OFF switch directly to the
robot controller.
CAUTION
This input power pass-through connection is intended
to supply power exclusively to the Fanuc R30iA con-
troller. It is designed to support a 3kW maximum robot
controller load through cable provided with the K2677-1
Integration Kit.

WARNING
ELECTRIC SHOCK CAN KILL.
DO NOT ATTEMPT TO BACK FEED INPUT
POWER THROUGH THE ROBOT POWER
TERMINAL BLOCK (4TB) INTO THE POWER
WAVE I400.
THIS IS NOT ITS INTENDED PURPOSE, AND MAY
RESULT IN MACHINE DAMAGE, BODILY INJURY OR
DEATH.

3. CHASSIS POWER TERMINAL BLOCK (3TB): Power connec-
tion for internal chassis. Provides power for the inverter and all
auxiliary supplies.
4. INPUT POWER TERMINAL BLOCK (1TB): Input power connec-
tion from main service disconnect.
5. GROUND TERMINAL: Earth ground connection.
6. PC BOARD DIPSWITCHES (NOT SHOWN): PC Board dip-
switches are set at the factory to allow configuration of the
POWER WAVE® i400 via the Fanuc Teach Pendant or with the
Weld Manager Utility (included on the POWER WAVE® Utilities
and Service Navigator
www.powerwavesoftware.com). The factory default settings are
as follows:
Control Board (G4800 Series Hardware):
• S1 = OFF
large
• S2 = ON
small
Feed Head Board (L11087 Series Hardware):
• S1 = OFF
1 thru 8
POWER-UP SEQUENCE
The POWER WAVE® i400 will typically be powered up at the same
time as the robotic controller. The status lights 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.

DUTY CYCLE

The
POWER WAVE® i400
with a 100% duty cycle. It is further rated to provide 400 amps at 34
volts with a 60% duty cycle and 420 amps at 35 volts with 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® i400
put current of 700 amps. The allowable maximum average output
current is time dependent, but ultimately limited to 450 amps over
any 2 second period. If the maximum average is exceeded, the
output is disabled to protect the machine. Under these conditions,
normal operation can be resumed by cycling the output command.
COMMON WELDING PROCEDURES
WARNING
MAKING A WELD
The serviceability of a product or structure utilizing the weld-
ing programs is and must be the sole responsibility of the
builder/user. Many variables beyond the control of The Lincoln
Electric Company affect the results obtained in applying these
programs. These variables include, but are not limited to, weld-
ing procedure, plate chemistry and temperature, weldment
design, fabrication methods and service requirements. The
available range of a welding program may not be suitable for
all applications, and the build/user is and must be solely
responsible for welding program selection.
