SAFETY INFORMATION
d) combustibles adjacent to walls, ceilings, roofs
or metal partitions can be ignited by radiant
or conducted heat.
After work is done, check that area is free of
sparks, glowing embers, and flames.
An empty container that held combustibles, or
that can produce flammable or toxic vapours
when heated, must never be welded on or cut,
unless container has first been cleaned. This
includes a thorough steam or caustic cleaning
(or a solvent or water washing, depending on
the combustible's solubility) followed by purging
and inerting with nitrogen or carbon dioxide,
and using protective equipment.
Water filling just below working level may
substitute for inerting.
A container with unknown contents should be
cleaned (see paragraph above), do NOT depend
on sense of smell or sight to determine if it is
safe to weld or cut.
Hollow castings or containers must be vented
before welding or cutting - they can explode.
In explosive atmospheres, never weld or cut
where the air may contain flammable dust, gas,
or liquid vapours.
Safe Handling of Shielding Gas Cylinders and
Regulators
Compressed gas cylinders should be handled
carefully and should be adequately secured
when in use. Knocks, falls, or rough handling
may damage cylinders or valves and may cause
leakage or an accident.
The following should be observed when setting
up and using cylinders of shielding gas:
store gas cylinders outside in a covered, well
ventilated
Properly secure the cylinder.
Before connecting a regulator to the cylinder
valve, the valve should be momentarily opened
and closed immediately to clear the valve of
dust or dirt that otherwise might enter the
regulator. The operator should stand to one side
of the cylinder valve, never in front of it.
After the regulator is attached, the adjusting
screw should be released by turning it anti-
clockwise. The cylinder valve should then be
opened slowly to prevent a surge of high
pressure gas into the regulator.
The cylinder valve should be shut off if it is to be
left unattended.
Specific Safety Instructions
Use the welding power supply as indicated in
the instruction manual. Improper use of this
welding power supply can be dangerous for
persons, animals or objects.
The user of the welding power supply is
responsible for their own safety and the safety
of others. It is important to read and understand
this instruction manual.
Repair and maintenance must be carried out by
qualified persons.
Maintain the welding power supply in good
condition (keep clean and dry etc).
During welding do not locate the welding power
supply in a confined space or close to a wall,
which will block air outlets.
Avoid stretching the supply cable, disconnect
from the mains supply before moving the
welding power supply.
Keep welding cables, earth clamp and electrode
holder in good condition.
Welders should not wear jewellery (especially
rings) or metallic watch straps.
Appropriate clothing should be worn. Gloves,
boots and overalls will provide some protection
from electric shock.
The welder should check daily, and after each
reconnection, that all external connections are
clean and tight.
When changing the MIG/MAG (Metal Inert Gas /
Metal Active Gas) electrode, the electrode
holder should be isolated.
When welding stops for a short time, the
MIG/MAG (Metal Inert Gas / Metal Active Gas)
wire electrode torch should NOT be put on the
face shield or flammable material as it may still
hot enough to cause damage.
