8. REPAIRS
Any repairs may be performed ONLY by persons authorized and trained by
the manufacturer.
9. DANGERS DURING WELDING
Prior to welding, authorized persons should thoroughly read this manual and
strictly observe all given instructions.
Non-compliance with these instructions may result in, among others, following
dangerous consequences.
9.1 FIRE, EXPLOSION
Observe fire regulations in force at the welding stand. Remove any flammable
materials in the vicinity of the welding stand. Prepare the appropriate fire-
fighting equipment. Keep in mind that due to sparks and welding arc high
temperature, there is a fire hazard even after a certain period after welding is
completed. Be especially careful when welding tanks used to store flammable
or combustible materials. If improperly cleaned before welding, may result in
explosion. Argon used for TIG welding is an inert gas and it can remove
oxygen from the atmosphere resulting in suffocation.
Often inspect gas cylinder, pressure regulator and gas hose. All joints should
be tight. Do not connect the gas cylinder directly to the gas hose without a
pressure regulator designed for argon. Do not use gas cylinders of which
content is uncertain.
The gas cylinder should always be secured in an upright position to a wall or a
specially designed cylinder rack. After welding always turn off the cylinder
valve. Handling of gas cylinders must always be done in accordance with the
manufacturer's instructions.
WARNING:
Gas cylinder may explode if dropped or fallen over.
9.2 BURNS
A welder must be fitted with a suitable non-flammable clothing, welding
gloves, suitable footwear and welding mask. High temperature of the arc,
welding splatter and ultraviolet radiation can cause dangerous injuries.
9.3 HARMFUL FACTORS
Welding process causes emission of vapours harmful to your health. Welding
stand should be provided with efficiently operating ventilation. If the ventilation
is not sufficient, use appropriate protective masks.
Without appropriate gas masks do not weld metals containing lithium,
cadmium, zinc, and beryllium.
