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.
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.
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" press the torch button
until the electrode wire leaves the contact tip of the
welding torch.
Take precaution to keep eyes and hands away from the
end of the torch while feeding wire.
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.
1. Motor shaft.
2. Mount ring.
3. Drive roll.
4. Cap.
To disassemble the drive roll you should:

Release the wire tension arm of the wire feeder.

Unscrew the fastening cap.

Take off the drive roll from the mount ring.
To assemble the drive roll you should:

Put on the drive roll onto the mounting ring.

Screw in the fastening cap onto the mount ring.

Insert the electrode wire.

Engage the wire tension arm of the feeder.
Decrease the
Gas Supplying
Put the gas cylinder on the machine shelf secure it with
the chain.
Take off the safety cap from the shielding gas cylinder and
install the flow regulator on it.
Connect the gas hose of the machine to the regulator with
the clamp band.
