2.0 Product Description
The XTM 353SW and 403SW are complete
semiautomatic constant voltage DC arc welding
machines built to meet CE specifications. They
combine a constant voltage power source and a
constant speed wire feeder with a microcomputer-
based controller to form a reliable high-performance
welding system. A simple control scheme, consisting
of a range voltage and wire feed speed controls,
provides versatility with ease of use and accuracy.
The machines also include built in water cooling and
recirculation units to allow the use of water cooled
torches. Other features include separate wire feed
unit for remote operation, an integral gas cylinder
mounting undercarriage, an adjustable Argon flow
regulator with cylinder pressure gauge and inlet
hose, a Parweld MIG torch, and a 3.0m work cable
with clamp. Digital meters display the actual welding
voltage and amperage and the machine has additional
controls for adjustment of burn back and soft starting.
3.0 Technical Specifications
T
he XTM353SW and 403SW are a separate type
machine with the wire feed unit connected to the
power supply but a 5m interconnecting cable for use
with 3 phase 400V supply.

4.0 Description of controls
1. Digital display for amperage and Voltage
(displayed real time)
2. Water cooler selector switch. This allows the
water recirculation pump and the flow switch
to be disabled when an Air cooled torch is
connected.
3. Mains input light This light illuminates when the
mains power is connected and the machine is
switched on.
4. On Off switch. The machine is switched off when
the light (4) is off and the fan is not running.
5. Fault light This light will illuminate when a fault or
over temperature condition has occurred. If this
light illuminates allow the machine to cool with
the fan still running until it extinguished. If the
light does not go off when the power source has
cooled down then have the machine checked by a
