OPERATION

1) Turn on the power source.
2) Adjust the wire speed, the power source voltage, the burnback time and the shielding gas according to
the wire diameter, thickness and material to be weld.
3) Start the welding and re-adjust the parameters, if needed.

MAINTENANCE

8.1) Recomendations
The wire feeder requires little maintenance in normal environment and opperation conditions. It is sufficient
to blow it dry clean using dry compressed air free from oil once a month.
After cleaning the equipment with blow dry air, check that the electric connections and components are
properly fixed. Check for possible faults in the wire isolations or electric cables, including the welding cable
and any others and if any of them is faulty change it.
When working with damaged cables or with worn out isolation, the non-isolated parts, can become in
contact with another part of an earth.The electric arc which results from this contact can hurt the eyes if not
protected and cause a fire. The body contact of a part with a cable without isolation can cause a violent
electric hazard, burns and even death.
Note: Cleaning and preventive maintenance should be intensified when operating in environment
contaminated by dust, soot or any other poluent which can cause damage or harm to the performance.

Check adjustments of speed and voltage of the power
Check if the feed roller gauge and type is appropriate
Check that the wire runs freely through the nozzle contact
Check if the shielding gas is appropriate
