CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the
correct shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. Always keep cylinders in an upright position securely chained to a fixed support. Do
not move or transport gas cylinders with the protection cap removed. Do not allow the electrode,
electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders
must be located away from areas where they may be subjected to physical damage or the welding
process including sparks and heat sources.
Installation and Operator Instructions
Read this entire section before installation or operation
of the machine.
Location and Environment
This machine will operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation.
•
Do not place or operate this machine on a surface
with an incline greater than 10°from horizontal.
•
This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover
the machine with paper, cloth or rags when
switched on.
•
Dirt and dust that can be drawn into the machine
should be kept to a minimum.
•
This machine has a protection rating of IP21. Keep
it dry when possible and do not place it on wet
ground or in puddles.
•
Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.
•
Do not use this machine for pipe thawing.
•
Do not operate in areas with an ambient
temperature greater than 40°C.
Duty Cycle and Overheating
The duty cycle of a welding machine is the percentage of
time in a 10 minute cycle at which the welder can
operate the machine at rated welding current.
Example: 60% Duty Cycle:
Welding for 6 minutes. Break for 4 minutes.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate. See “Technical
Specification”.

Input Supply Connection
WARNING
Equipment shall only be used on a supply system
that is a three-phase, four-wire system with an
earthed neutral.
Installation and mains outlet socket shall be made and
protected according to appropriate rules. Check the input
voltage, phase, and frequency supplied to this machine
before turning it on. For more information about input
supply refer to the technical specification section of this
manual and to the rating plate of the machine. Verify the
connection of grounding wires from the machine to the
input source.
Wire Feeder Connection
To connect the wire feeder to the power source Magster
380 or 450 you should use the combined cable (see
chapter “Accessories”) and do the following:
Connect the combined cable to the socket marked by
.
Connect the control cable to the socket marked by
To connect the wire feeder to the semi power source
Magster 450W you should use the combined cable (see
chapter “Accessories”) and do the following:
Connect the combined cable to the socket marked by
.
Connect the control cable to the socket marked by
.
Disconnect the hose, which closes the circuit of the
water cooling system and connect hoses to the
welding source and wire feeder according to colour
marks (the blue hose to the socket with blue
bordering).
Wire diagram of the welding source and wire feeder is
shown in the chapter “Wiring Diagrams”.
Ground Cable Connection
Connect the ground cable to one of the two sockets ,
additionally marked by:
: high inductance output socket.
: low inductance output socket.
Shielding Gas Connection
To connect shielding gas you should do the following:
After placing the gas cylinder on the gas cylinder
mount, protect it from overturn with the chain.
Take off the cap over the safety valve of the shielding
gas cylinder.
