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.
