prevent falling or tipping. Keep cylinders away from
any welding or other electrical circuits. Never drape
a welding torch over a gas cylinder. Never allow a
welding electrode to touch any cylinder. Never weld
on a pressurized cylinder - explosion will result. Use
only correct shielding gas cylinders, regulators, hoses,
and fittings designed for the specific application;
maintain them and associated parts in good condition.
Turn face away from valve outlet when opening
cylinder valve.
Use the right equipment, correct procedures,
and sufficient number of persons to lift and move
cylinders.
Read and follow instructions on compressed gas
cylinders, associated equipment, and Compressed Gas
Association (CGA)
2.0 Product Description
The XTM 353S and 403S 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.
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
The XTM353S and 403S 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.
