Three-function Welding Machine
retention force of the spool. The coil should
rotate freely, but no wire loops should form
during operation. If hinges are formed, tighten
the adjusting screw more. If the spool is diffi-
cult to turn, loosen the screw.
porarily turn on the power by switching the
switch and press the button 21 (wire feed)
until it fills the channel of the welding sleeve
and leaves the torch. Disconnect the power
supply. Note! For free passage of the wire in
the cable, straighten it along its entire length.
When feeding the wire, make sure it moves
freely in the drive roll channel and that the
feed speed is uniform. If the feed rate is un-
even, adjust the pressure of the pinch roller.
Match and screw in a contact tip that matches
the wire diameter and installs the nozzle.
Semi-automatic welding modes
This machine can work with two types of
welding wires: solid copper-coated wire in a
shielding gas environment, and self-shielded
flux-cored wire, in which case a gas cylinder
is not required.
Different types of filler wire require a different
wiring diagram.
Gas welding (GAS) with solid cop-
per-plated wire:
–
Connect the short cable with the connector
located at the bottom of the front panel of
the device to the left connector on the front
panel (“+” terminal).
–
Fix the grounding terminal on the work-
piece to be welded, connect the connector
on the other end of the cable to the right
connector on the front panel (“-” terminal).
–
Check the markings on the feed roll ac-
cording to the wire diameter being used.
–
Insert the spool of wire into the slot.
–
Feed the wire into the torch by folding
back the roll clamp and inserting the wire
into the channel through the recess in the
roll.
–
Close the roller clamp by slightly tightening
the clamping screw.
–
Make sure to match the hole diameter of
the gun tip to the wire diameter.
–
Turn on the machine and run the wire until
it exits the tip by pressing the trigger on
the torch.
–
Connect the hose from the gas regulator
to the fitting on the back of the device.
–
Open the valve on the shielding gas cylin-
der, press the torch trigger and adjust the
gas flow with the reducer (usually the gas
flow is set as follows: gas flow (l / min) =
Wire diameter (mm) x 10.
–
Set the required welding mode using the
controls.
–
Begin welding.
Inserting the wire into the wire lin-
er
Loosen and lower the adjuster towards you.
Raise the pinch roller;
Cut off the bent end of the wire and thread the
wire into the wire liner of the feeder, align it
in the channel of the drive roll. Make sure the
bore of the roller matches the diameter of the
wire;
Place the wire in the welding torch connector
bore, release the pinch roller, and return the
adjuster to the vertical position.
Adjust the pressure of the pinch roller.
–
When welding with steel wire, the V-groove
of the drive roll must be used;
–
When using flux-cored wire, the gear
groove of the drive roll must be used
(availability depends on the model and
equipment of the device).
–
When using aluminum wire, the U-groove
of the drive roll must be used (availability
depends on the model and equipment of
the machine).
Wire feed into the welding arm
Unscrew the welding tip on the torch.
To feed the wire into the torch sleeve, tem-
