DESCRIPTION OF EQUIPMENT
General
The Ultra Flex
®
350 is a DC inverter power source
that can be used for Constant Current (CC), Con-
stant Voltage (CV), and Pulse welding applications.
The DC output is produced by an inverter operating
at 20 kHz utilizing Insulated Gate Bipolar Transis-
tors (IGBT). The output is rated for 350 amps at 34
volts and 60% duty cycle. The power source will
operate from either single or three phase input
power.
Controls for the following welding processes are
built into the Ultra Flex
®
350 power source: Shielded
Metal Arc Welding (Stick) with arc force control, Gas
Tungsten Arc Welding (TIG) with Lift-Arc, and Gas
Metal Arc Welding (MIG/MAG) with variable induc-
tance control. The Ultra Flex
®
350 Pulse machine
also has controls built in for pulsed Gas Metal Arc
Welding. The pulse control includes 8 pre-pro-
grammed factory pulse schedules with the ability to
override any or all eight schedules using the op-
tional programming pendant (204180A-1).
The Ultra Flex
®
350 power source also contains
several protection features to assure continued,
reliable operation. The features include: AC input
over and under voltage sensing and shutdown,
output overload shutdown, overtemperature shut-
down, short circuit protection, ground fault current
shutdown for the remote receptacle, and sin-
gle/three phase detection. During the initial power
up sequence the input voltage and the inverter DC
capacitor voltage are sensed. If any voltage is not
correct the input circuit will be safely disabled pro-
tecting the inverter from damage.
