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, constantly hold
it at a distance equal to the electrode diameter and at an angle of
approximately 20º – 30º in the direction in which you are welding.
Heating stop indication
If the warning light is switched on (E), means that the thermal
protection is already on.
If the duty cycle "X" shown on the data plate is exceeded, a thermal
cutout stops the machine before any damage is caused. Wait for the
operation to be restored and, if possible, wait for a few minutes more
until the gear factor is complied.
If the thermal protection is continuously on, means that the machine
is overworking.
"Hot start"
The welding machine is fitted with an automatic device that
facilitates the striking of the arc, increasing the current only at that
very moment.
"Antisticking"
The welding machine is fitted with an automatic device that interrupts
the current for a few seconds after having detected that the electrode
has tuck to the piece to be welded. By doing so, the electrode will
not overheat.
RECOMMENDATIONS FOR USE
- Only use an electrical extension cord 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 a suitable
ventilation.
- Do not use the welder in any environment where in presence of
gas, vapors, conductive powders (e.g: iron shavings), brackish air,
caustic fumes or other agents that could damage the metal parts and
the electrical insulation.
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.
MAINTENANCE
Switch off the welder and remove the plug from the power socket
before carrying out any maintenance operation.
Extraordinary maintenance of the machine must be periodically
carried out by expert staff or qualified electrical mechanics,
depending on the use.
- Inspect the inside of the welder and remove any deposited dust on
the electrical parts (by using compressed air), and in the electronic
cards (using a very soft brush and appropriate cleaning products).
- Check that the electrical connections are tight and the insulation on
the wiring is not damaged.
