1. GENERAL DESCRIPTION
UWW-161 TP is a compact and portable Single Phase Inverter Power Source for professional MIG-MAG,
TIG and MMA welding.
It connects to a standard 230V one phase socket, preferably with slow fuses to allow full power.
The TP (total protection) version is protected against too high input voltage and will close down 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.
The automatic Voltage Reducing Function provides operator safety by reducing “touchable” voltage for the
operator to max. 10V between electrode holder and work-piece.
The automatic Amperage Draw Protection will cut the current to prevent damage to the machine, and sound
an alarm tone to warn the operator if welding with the set wire welding parameters exceeds the capacity of
the unit.
UWW-161 TP is easy to transport, only 12kg weight and it is specifically designed for light fabrication,
maintenance and repair work on board.
It offers excellent MIG-brazing characteristics using CuSi3 and CuSi6 type wires.
Polarity change for Euro-connector allows welding with self shielded wires.
User-friendly control panel allows precise parameters settings using only two knobs.
Selection between a softer and crisper arc allows optimal arc for various wires.
Built-in wind tunnel cooling protects electronic devices from dust and saltiness, improving the UWI-161 MP
arc welder’s life cycle.
• Light weight and reliable
• Up to 3,25mm electrodes in MMA
• Lift arc TIG DC ignition reduces Tungsten inclusions without generating the radio interference that High
frequency arc start may cause.
• Excellent MIG/MAG welding properties.
• Polarity selection for self-shielded wire welding.
