welding pool and the transferring droplets

against oxygen and nitrogen in the

surrounding air. The electrode melts during

welding. A part of the coating vaporises so a

protective gaseous shield originates.

part of the coating floats on the welding pool (it

is lighter than steel) and also protects the

cooling weld. After cooling this coating

becomes a solid but easily removable slag on

the welded joint.

• Handle the electrodes with care so the coating

is not broken. Make sure that the electrodes

are thoroughly dry, so store them in a

moisture-free place.

• It is of great importance to use the right

electrode to make a good and strong welded

joint. A universal electrode will in many cases

be suitable for your work.The electrode

packaging mentions in which positions

welding can be done with the electrodes

concerned (above the head, downwards, etc.

bearing in mind the speed of melting of the

electrode). Separate electrodes are

commercially available for the welding of types

of stainless steel and cast iron. Consult your

dealer about purchasing the right electrode.

c. Protective clothing

Wear thoroughly covering clothing so that the

likelihood of the skin being burnt by ultraviolet

radiation or splashes of metal is minimised.

Preferably wear cotton overalls, welding gloves

and safety shoes. Make sure that welding spatter

cannot end up in gloves or shoes.

A (leather) welding apron stops burning and

sparks damaging overalls.

d. Face protection

Fig. 2

Use a good welding mask with (dark) welding

glass and protective glass. Check that both

glasses are correctly fitted (well-fastened and not

allowing any sunlight in).

The welding mask protects the welder against

radiation, heat and weld spatter released during

the welding process. This also reduces the

inhalation of welding fumes. The invisible

ultraviolet rays cause so-called “welder’s flash”.

This already originates after a few seconds of

looking into the electric arc.

Avoid the effects of this radiation and high

temperatures on the face and other exposed body

parts such as the neck and arms.

Protect yourself against the dangerous effects of

the electric arc and keep persons who are not

participating in the work at least 15 m from the arc.

Persons or assistants working in the vicinity of the

electric arc must be advised of the hazards and

they must be equipped with the required protective

gear. If required, set up protective walls.

e. Working environment

• Ensure a well ventilated working environment.

Gases are released when welding that are a

danger to your health.

• Remove all flammable objects from the

working environment. Welding causes sparks

and hot metal.

• Make sure that cooling water is present in the

vicinity of workplace. Do not leave just welded

(hot) workpieces unattended in the workplace.

Cool the workpiece before leaving the

workplace.

Protection against radiation and burns

• At the work place, the hazard to the eyes must

be indicated by a sign stating “Caution! Do not

look at the flames!” The workstations must be

shielded as much as possible in such a

manner that personnel standing in the vicinity

of the workstation are protected. Keep

unauthorized personnel away from the

welding work.

• In the immediate vicinity of the stationary

workstations, the walls should not be brightly

colored or glossy. Windows must be coated

with suitable paint to at least eye-level to

prevent radiation reflecting or passing

through.

Bringing into use

Tip: Before you start welding difficult workpieces it

is best to first try the welding out on a test piece.

• Ensure a clean workpiece: remove any rust,

grease and paint residues.

• Set the required current intensity using the

knob on the front of the welding appliance.

The choice of current intensity depends on the

workpiece and the type of electrode used.

• Place the part of the electrode without coating

in the electrode holder and connect the earth

terminal to the workpiece.

• Switch the welding appliance on with the main

switch.

• Keep the welding mask in front of your face

and move the point of the electrode over the
