HUMIDITY
Never weld in wet or humid environments.
DAMAGED CABLES
Never use damaged cables. (This
applies to both the power and the
welding cables.)
Never remove the unit side panels. If
the side panels can be opened, always
checked they are closed tightly before
starting any work.
FIRE PREVENTION
Together with the previous instruc-
tions, the following precautions
should be strictly observed. Welding
operations require high tempera-
tures therefore the risk of fire is
great.
WORK-AREA FLOORING
The work-area flooring MUST be
fireproof.
WORK-AREA SURFACES
Work benches or tables used during
welding MUST have fireproof surfaces.
WALL AND FLOOR PROTECTION
The walls and flooring surrounding
the cut environment must be shielded
using non-flammable materials. This
not only reduces the risk of fire but also
avoids damage to the walls and floors
during cut processes.
EXTINGUISHER
Place an approved and appropriate-
ly-sized fire extinguisher in the work
environment. Check its working
order regularly (carry out scheduled
inspections) and ensure that all parties
involved know how to use one.
CLEAN ENVIRONMENT
Remove all flammable materials away
from the work environment.
SERIOUS DANGER!
NEVER cut in confined spaces (e.g. in a
container vehicle, a cistern or a store-
room etc.) where toxic, inflammable or
explosive materials are, or have been,
located or stored. Cisterns, in particu-
lar, may still contain toxic, flammable or
explosive gases and vapors years after
they have been emptied.
NEVER cut a cistern that contains
(or has stored) toxic, inflammable or
explosive materials. They could still
contain toxic, flammable or explosive
gases and vapors years after they have
been emptied. If you are oblie to weld
a cistern, ALWAYS passivate it by filling
it with sand or a similar inert substance
before starting any work.
NEVER use the Welder to melt frozen
water pipes.
VENTILATION
Together with the previous instruc-
tions, the following precautions
should be strictly observed.
WELDING ENVIRONMENT VENTI-
LATION
Ventilate the cut environment careful-
ly. Maintain sufficient airflow to avoid
toxic or explosive gas accumulation.
Cut processes on certain kinds or com-
binations of metals can generate toxic
fumes. In the event of this happening,
use air-supply respirators. BEFORE cut,
read and understand the welding alloy
safety provisions.
PROTECTIVE WELDING GASES
Together with the previous instruc-
tions, the following precautions
should be strictly observed when
welding with protective gases.
GAS TYPES
These welders use only inert (non-flam-
mable) gases for welding arc protec-
tion. It is important that the appropri-
ate type of gas is chosen for the type of
welding being performed.
UNIDENTIFIED GAS CYLINDERS
Never use unidentified gas cylinders.
PRESSURE REGULATOR
NEVER connect the cylinder directly
to the welder. Always use a pressure
regulator.
Check the regulator is performing its
function properly. Read the regulator
instructions carefully.
Never lubricate any part of the regu-
lator.
All regulators are designed for a spe-
