OPERATION
General
Read and understand the safety instructions at the
beginning of this manual prior to operating this
machine.
WARNING: Be sure to put on
proper protective clothing and
eye safeguards (welding coat,
apron, gloves, and welding hel-
met, with proper lenses in-
stalled). See Safety Instructions
and Warnings chapter included
in this manual. Neglect of these
precautions may result in per-
sonal injury.
WARNING: Make all connec-
tions to the power source includ-
ing electrode and work cables,
as well as remote control cables,
with the power source turned
off. These connections could be
electrically live with the power
switch ON.
This first section on the operation of the machine
will describe the general operation of the control
panel and digital display. Most of this information is
the same no matter what type of welding is being
done. Following sections give specific instructions
for each welding process or mode of operation.
The bottom group of four buttons on the control
panel are used to select the welding process or
mode of operation. For the Ultra Flex
®
350 Pulse the
following modes are available: SMAW, LIFT
GTAW, GMAW, and GMAW PULSED. The first
step would be to select the correct mode depending
on the welding process to be used. To select a weld
mode, momentarily press the appropriate button.
The light next to the switch should come on indicat-
ing that it is now the active mode.
The A/V button is used to select amps or volts as
the adjustable value shown on the display. To pre-
set amps or volts first press the A/V button and then
use the UP and DOWN buttons to set the value. If
the UP or DOWN button is held for more than two
seconds, the display will scroll at a more rapid rate.
During welding the A/V button is used to toggle
between actual weld amps and actual weld volts.
To adjust amps or volts while welding use the UP
or DOWN buttons. The display will automatically
switch to showing the set amps or set volts.
The AF/IND button is used to select arc force when
Stick welding and inductance when MIG welding.
Both arc force and inductance have a range of 0 to
100, with 100 being the maximum setting. To set arc
force or inductance first press the AF/IND button
and then use the UP and DOWN buttons to set the
value. Arc force and inductance can also be ad-
justed while welding.
The SCHEDULE button on the Ultra Flex
®
350
Pulse machine is used to select one of the eight
available Pulse MIG schedules. To select the
schedule, first press the SCHEDULE button and
then use the UP and DOWN buttons to set the
schedule number on the display. The schedule
number can not be changed while welding.
The REMOTE button is used to select remote
amperage/voltage control through the 19 pin recep-
tacle on the rear of the machine. Pressing the button
once will toggle remote control on, pressing the
button again will toggle remote control off. When the
light next to the switch is on, remote control is active.
For all modes except TIG, the remote control will
allow full scale adjustment of the output. For TIG
modes it is necessary to first set the maximum
welding amperage using the front panel of the ma-
chine. The remote control will then have control
from zero to this maximum setting.
The CONTACTOR button is used to energize the
output of the power source. There really is no con-
tactor being energized, the solid state control uses
the signal to “turn” the output on. Pressing the
button once will turn the output on. Pressing it again
will turn the output off. When the output is on, the
light next to the CONTACTOR button will be lit.
Normally the CONTACTOR button would be used
for Stick or TIG welding when a torch switch or foot
pedal is not being used. If a remote control, such as
a hand pendant, is being used then the contactor
can be controlled at the remote control. Whenever
