6.4) Wire feed pressure
Start by making sure that the wire moves smoothly through the wire guide.Then set the pressure of the wire
feeder's pressure rollers. It is important that the pressure is not too great.
To check that the feed pressure is set correctly, you can feed out the wire against an insolated object, e.g. a
piece of wood.
When you hold the gun approx. 5 mm from the piece of wood (pic.1) the feed rollers should slip.
If you hold the gun approx. 50 mm from the piece of wood, the wire should be fed out and bend (pic.2).
6.5) Adjusting the braking torque
NOTE
The hub is adjusted when delivered, if readjustment is required, follow the instructions below. Adjust the
brake hub so that wire is slightly slack when wire feed stops.
Turn the red handle to the locked position.
Insert a screwdriver into the springs in the hub.
Turn the springs clockwise to reduce the braking torque.
Turn the springs counterclockwise to increase the braking torque.
: In order to latch or unlatch, just turn the red handle. There´s no need to remove it.
Note:Turn both springs through the same amount.

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.
7 OPERATION
8 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.
Type
No arc
No feeding of wire
Bad welding
The wire paste in the welding pond and when the
welding is finish the wire presents a great length in
contact tip of the torch.
Action
Check if the power source switch is on.
Check if the work cable is connected .
Check for feeding the wire
Check adjustments of speed and voltage of the power
source.
Check if the feed roller gauge and type is appropriate
of wire used.
Verify that the mechanism of pressure is properly
adjusted
Check the pressure setting of the brake rub.
Check that the wire runs freely through the nozzle contact
torch .
Check if the shielding gas is appropriate the wire
used, flowing at the torch nozzle and the flow is correct
Verify that the speed of the wire, the voltage set in power
source and the burn-back time are properly adjusted.
Check the fit of the time of burn-back
with
.
