1 SAFETY RULES CONCERNING THE USE OF THIS
WELDING MACHINE
1.1 INTRODUCTION
All people authorized to use this machine should read the
following instructions manual before using or servicing this
unit.
A REMINDER: YOUR SAFETY DEPENDS ON YOU!!!
Always follow all safety regulations and instructions when
using this machine. It is your responsibility to protect
yourself and others against the risks related to the operation
of this welding machine. The operator must be familiar with
and observe all the safety rules regarding the safe operation
and maintenance of this welding machine.
NOTHING REPLACES GOOD COMMON SENSE !!!
1.2 GENERAL PRECAUTIONS
1.2.1 Fire
• Avoid causing fires due to sparks, slag,
hot metal and spatter which are produced
during normal welding operations.
• Make sure that a suitable fire-
extinguisher is located near the welding sight.
• Remove all flammable material within 30 feet of the
welding area.
• Do not weld containers (tanks or drums) containing
flammable material, even when empty.
• Allow the welded metal to cool down before touching it or
putting it into contact with flammable material.
• Do not weld structures with hollow spaces containing
flammable substances.
• Do not work in conditions where there are high concentra-
tions of combustible vapours, gases, or flammable dust.
• Always check the work area half an hour after welding so
as to make sure that no fire has started.
• Do not keep any flammable material such as lighters or
matches in your pockets while using this equipment.
1.2.2 Burns
• Protect your entire body by wearing fire-proof clothing
This will protect your skin against burns caused by: ultra-
violet radiation given off by the arc, sparks and molten slag.
• The protective clothing should include: gloves, a hat, and
high shoes. Your shirt collar and pocket flaps should be
buttoned , and cuff-less trousers should be worn to prevent
contact with sparks and molten slag.
• Wear a helmet equipped with the appropriate lens shade
and a clear glass cover plate. This is imperative when
welding, cutting, and chipping to protect your eyes from
ultra-violet arc rays and molten spatter. Replace the glass
cover plate when cracked or covered with spatter etc.
• Do not wear clothing spotted with oil or grease as a spark
may set them on fire.
• Hot metal, electrode stubs and workpieces, should never
be handled without gloves.
• First-aid equipment and a qualified first-aid person should
always be available when welding, unless medical facilities
are in the immediate vicinity, to treat flash burns of the eyes
and skin burns.
• Ear plugs should be worn when working in the overhead
position or in confined spaces. A hard hat should be worn
when others are working overhead.
• Flammable hair sprays and gels should not be used by
those persons intending to weld.
1.2.3 Fumes
Welding operations produce harmful fumes and
metal dusts which may be hazardess to your
health, therefore:
• Work in well-ventilated areas.
• Keep your head out of the fumes.
• In closed areas, use a fume exhaust system, preferrably
placed under the welding area if possible.
• If ventilation is inadequate, use an approved respirator
set.
• Clean the metal to be welded of any solvents or halogen
degreasers which give rise to toxic gases. During some
welding operations clorine solvents may be decomposed
by arc radiation thus creating phosgene gas.
• Do not weld coated metals or those containing lead,
graphite, cadmium, zink, chrome, quicksilver, or mercury
unless you have an approved respirator set.
• The electric arc creates ozone. Long exposures to high
ozone concentrations may cause headaches; nasal, throat
and eye irritation; as well as congestion and chest pains.
WARNING: NEVER USE OXYGEN FOR VENTILATION.
• Gas leaks in confined spaces should be avoided. Leaked
gas in large quantities can dangerously alter oxygen levels
in the air surrounding the weld sight. Do not place gas
cylinders in confined spaces.
• DO NOT WELD where solvent vapors can be drawn into
the welding shield atmosphere or where arc rays can come
into contact with even minute quantities of trichloroethylene
or perchloroethylene.
1.2.4 Explosions
• Do not weld above or near containers under
pressure.
• Do not weld in environments containing
explosive dusts, gases or vapours.
This welding machine when used for TIG welding uses
ARGON gas to shield the arc. Special precautions must be
taken when transporting, handling, and connecting gas
cylinders.
A) GAS CYLINDERS
• NEVER DEFACE or alter the name, number, or other
markings on a cylinder. It is illegal and dangerous!
• Do not use cylinders whose contents are not clearly
identified.
• Do not directly connect cylinder to the unit without using
a pressure regulator.
• Handle and use pressure cylinders with care and in
conformity with existing safety standards.
• Do not use leaking or damaged cylinders.
• Do not use cylinders which are not well secured.
• Do not transport or move cylinders without the protection
of the installed valve and protective valve cap.
• Do not lift cylinders off the ground by: their valves or caps,
by chains, by slings, or by magnets.
• Never try to mix gases in a cylinder.
• Never refill a cylinder!
