Safety instructions
S/4
Transport and set-up
Machines may only be moved and operated in an upright position.
Before moving, pull out mains plug and place on the machine.
Secure high-pressure shielding gas cylinder with safety chain to prevent it from toppling
over.
When setting up the machine, tilt resistance is only guaranteed up to an angle of 15°
(as specified in EN 60974).
Environmental conditions:
The welding machine can be operated in a location where there is no risk of explosion at
·
an ambient temperature
of -10°C (plasma machines 0°C) to +40°C and
·
a relative air humidity
up to 50% at 40°C.
·
where the surrounding air is free of unusual amounts of dust, acids, corrosive gases or
substances etc., insofar as they do not occur during welding.
Examples of unusual operating conditions:
Unusual corrosive smoke, vapour, excessive oil vapour, unusual vibrations or jolts, excessive
quantities of dust such as grinding dust etc., severe weather conditions, unusual conditions near
the coast or on board ship.
·
When setting up the machine, ensure that air inlets and outlets are unobstructed.
The machine is tested to Protection Standard IP23, i.e.:
·
Protection against penetration of solid foreign bodies
Æ
> 12mm,
·
Protection against water spray up to an angle of 60° to the vertical.
Notes on the use of these operating instructions
These operating instructions are arranged in Sections.
To help you find your way around more quickly, in the margins you will occasionally see, in addition
to sub-headings, icons referring to particularly important passages of text which are graded as
follows depending on their importance:
(Note): Applies to special technical characteristics which the user must note.
(Warning):
Applies to working and operating procedures which must be followed
precisely to avoid damaging or destroying the machine.
(Caution):
Applies to working and operating procedures which must be followed
precisely to avoid endangering people and includes the “Warning” symbol.
Instructions and lists detailing step-by-step actions in given situations can be recognised by bullet
points, e.g.:
·
Insert plug of welding current lead into socket (Sect. 5, G2) and lock.
Meaning of the diagram descriptions:
e.g. (C1) means:
Item C / Figure 1 in the respective Section
e.g. (Sect. 3, C1) means:
in Section 3 Item C / Figure 1
