has dropped to normal.
Personal Protection:
– The body should be protected by suitable clothing.
– The use of neck protection may be necessary against reflected radiation.
– Wear safety glasses when chipping, wire brushing, grinding or when near cooling welds as metal
filings or slag can be thrown up. Fully enclosed goggles are advisable.
– Arc machines generate a magnetic field which is detrimental to pacemaker recipients.
Consult your doctor before going near welding equipment/operations.
– The UV and IR radiation generated by welding is highly damaging to the eye, causing burns.
This can also affect the skin. Protect the eyes and face.
– The face and eyes shall be protected by suitable welding shields equipped with appropriate
occural protection filters.
– Where environments are subject to pedestrians and traffic ensure a protective screen is
used to avoid accidental arc glare.
- Do not weld in the vicinity or children or animals and ensure no one is looking before
striking up.
– In the welding environment, damaging levels of noise can exist. Wear hearing protection if
the process dictates.
– Do not touch hot equipment or metal. Allow the weld time to cool, use the correct tool and
wear protective welding gauntlets.
– Wear flame retardant clothing (leather, wool, etc.).
– Take care when adjusting or maintaining the torch that it has had time to cool sufficiently
and is disconnected.
– The arc generates
• ultra-violet radiation (can damage skin and eyes);
• visible light (can dazzle eyes and impair vision);
• infra-red (heat) radiation (can damage skin and eyes);
– Such radiation can be direct or reflected from surfaces such as bright metals and light
coloured objects.

NOTE: Once you have put the welding machine
into operation, switch it on and carry out the
required adjustments.
9.1 ADJUSTING THE WELDING
CURRENT
Select the welding current depending on the
electrode, the joint and the welding position.
Indicatively, the currents to be used with the
different electrode diameters are listed in Fig.2.
NOTE: Do not force the adjustment flywheel as
this could damage the welding machine. Check
the adjustment on the current adjustment
indicator.
NOTE: To strike the welding arc with the coated
electrode, brush it onto the piece to be welded
and as soon as the arc is struck, hold it constantly
at a distance equal to the electrode diameter and
at an angle of approximately 20-30 degrees in the
direction in which you are welding.
9.2 THERMAL CUTOUT SIGNAL
The warning light switched on means that the
thermal protection is running.
If the welding time is exceeded, a thermal cutout
stops operation before the welder is damaged.
Wait for operation to be resumed and, if possible,
wait a few minutes more.
If the thermal cutout continues to cut in, the
welding machine is being pushed beyond its
normal performance levels.
9.3 RECOMMENDATIONS FOR USE
Only use an extension lead when absolutely
necessary and providing it has an equal or larger
section to the power cable and is fitted with a
grounding conductor.
Do not block the welder air intakes. Do not store
the welder in containers or on shelving that does
not guarantee suitable ventilation.
Do not use the welder in any environment in the
presence of gas, vapours, conductive powders
(e.g. iron shavings), brackish air, caustic fumes or
other agents that could damage the metal parts
and electrical insulation.
NOTE: The electric parts of the welder have been
treated with protective resins. When used for the
first time, smoke may be noticed; this is caused
by the resin drying out completely. The smoke
should only last for a few minutes.
