1 GENERAL DESCRIPTION
UWI-150 TP is a compact and portable single phase inverter power source for professional MMA,
TIG and TIG-pulse welding.
It connects to a standard 230V one phase socket, preferably with 16A slow fuses to allow full power.
The TP (total protection) function protects against too high input voltage and will close down the
machine completely to prevent damage if input voltage exceeds 285V. A led on the rear panel will be
lit to indicate that the protection is on. When the input voltage is reduced welding power will
automatically be restored.
Safe in use. The automatic Voltage Reducing Function provides operator safety by reducing
“touchable” voltage for the operator to max. 9V between electrode holder and work-piece.
Line voltage compensation keeps output of the power source constant regardless of fluctuation in
input power from 15% below to 15% above rated input voltage.
Automatic Hot Start for stick arc starts makes arc striking easy and prevents electrode sticking.
Automatic Arc Force for stick electrode welding provides optimal arc characteristics for MMA (stick)
welding.
Lift-Start in TIG mode provides easy and soft TIG arc starting, and both normal and pulsed TIG
current enables optimal current also for sheet metal.
Step-less adjustment of welding current through whole current range: 5
–150A, and remote control
that can be attached to the TIG torch provides excellent control through the welding process.
Casing of high grade aluminium and industrial plastic to eliminate corrosion damage also contributes
to low-weight which together with compact outer dimensions provides good portability.
Wind tunnel design for the internal cooling air flow protects electrical components and PC boards
from dirt, dust, debris, greatly improving reliability.
Thermal overload protection with indicator lights helps prevent machine damage if the duty cycle is
exceeded or airflow is blocked.
Total Protection function with indicator light prevents machine damage if excess voltage peaks in the
