Danger from
shielding-gas
cylinders
Safety precauti-
ons at the instal-
lation site and
when being
transported
Shielding-gas cylinders contain pressurized gas and may explode if they are
damaged. As shielding-gas cylinders are an integral part of the overall
welding outfit, they also have to be treated with great care.
Protect shielding-gas cylinders containing compressed gas from excessive
heat, mechanical impact, slag, naked flames, sparks and arcs.
Mount the shielding-gas cylinders in the vertical and fasten them in such a
way that they cannot fall over (i.e. as shown in the instruction manual).
Keep shielding-gas cylinders well away from welding circuits (and, indeed,
from any other electrical circuits).
Never hang a welding torch on a shielding-gas cylinder.
Never touch a shielding-gas cylinder with a welding electrode.
Explosion hazard - never perform welding on a pressurized shielding-gas
cylinder.
Use only shielding-gas cylinders that are suitable for the application in
question, together with matching, suitable accessories (pressure regulators,
hoses and fittings, ...). Only use shielding-gas cylinders and accessories that
are in good condition.
When opening the valve of a shielding-gas cylinder, always turn your face
away from the outlet nozzle.
Close the shielding-gas cylinder valve when no welding is being carried out.
When the shielding-gas cylinder is not connected up, leave the cap in place
on the shielding-gas cylinder valve.
Observe the manufacturer's instructions and all relevant national and
international rules applying to shielding-gas cylinders and accessories.
A machine that topples over can easily kill someone! For this reason, always
place the machine on an even, firm floor in such a way that it stands firmly.
- An angle of inclination of up to 10° is permissible.
Special regulations apply to rooms at risk from fire and/or explosion. Observe
all relevant national and international regulations.
By means of internal instructions and checks, ensure that the workplace and
the area around it are always kept clean and tidy.
The appliance must only be installed and operated in accordance with the
protection type stated on the specifications plate.
When installing the appliance, please ensure a clearance radius of 0.5 m
(1.6ft.) , so that cool air can circulate freely.
When transporting the appliance, please ensure that the valid national and
regional guidelines and accident protection regulations are followed. This
applies in particular to guidelines in respect of dangers during transportation
and carriage.
