Loading the Wire Spool
Load the wire spool on the sleeve such that the spool
turns clockwise when the wire is fed into the wire feeder.
Machine is designed to use 15kg (300mm) wire spool.
1. Sleeve
2. Wire spool
3. Electrode wire
4. Feeding unit
Make sure that the spool locating pin on sleeve goes into
the fitting hole on the spool.
Free the end of the wire and cut off the bent end making
sure it has no burr.
Rotate the wire spool clockwise and thread the end of
the wire into the entrance guide tube pushing it into the
wire guide of the welding torch.
Feeding the Electrode Wire
Rise side cover of the machine.
Put on the drive roll using the correct groove
corresponding to the wire diameter.
Load the spool of wire onto the sleeve of the machine.
Free the end of the wire and cut off the bent end making
sure it has no burr.
Insert the electrode wire into to the wire feeder and into
the Euro socket.
Properly adjust the wire tension arm of the feeder.
Adjustments of Brake Torque of Sleeve
To avoid spontaneous unrolling of the welding wire the
sleeve is fitted with a brake.
Adjustment is carried by rotation of its screw M10, which
is placed inside of the sleeve frame after unscrewing the
fastening cap of the sleeve.
1. Fastening cap.
2. Adjusting screw M10.
3. Pressing spring.
Turning the screw M10 clockwise increases the spring
tension and you can increase the brake torque.
Turning the screw M10 counterclockwise decreases the
spring tension and you can decrease the brake torque.
After finishing of adjustment, you should screw in the
fastening cap again.
Adjusting of Force of Pressure Roll
Force
Before welding you should understand how to properly
set the wire tension.
Pressure force is adjusted by turning the adjustment nut
clockwise to increase force, counterclockwise to
decrease force.
WARNING: If the roll pressure is too low the roll will
slide on the wire. If the roll pressure is set too high the
wire may be deformed, which will cause feeding
problems in the welding gun. The pressure force should
be set properly. Decrease the pressure force slowly until
the wire just begins to slide on the drive roll and then
increase the force slightly by turning of the adjustment
nut by one turn.
Inserting Electrode Wire into Welding
Torch
Remove the gas diffuser and contact tip from the
welding gun.
Set wire feeding speed knob in its central position.
After switching the machine "ON" (power switch in
position "I") and wire test (gas test switch set in position
"wire test") until the electrode wire leaves the contact tip
of the welding torch.
WARNING: Take precaution to keep eyes and hands
away from the end of the torch while feeding wire.
WARNING: Once the wire has finished feeding through
the welding gun turn the machine "OFF" before replacing
to contact tip and gas diffuser.
Assembling of the Drive Roll of the
Wire Feeder
The machine has V0.8/V1.0 drive roll in standard. The
picture below shown the assembly of drive roll for 0.8
solid wire.
