3.1.3.3 Welding with Spool Gun (option)
The torch current clamp should be connected to the MIG torch socket (1). Insert the polarity
change plug (4) in the socket (3). Connect the negative pole of the source (5) to the work-
piece using a cable with a clamp. Connect the device's plug to a 230V 50Hz wall socket.
Switch (11) located inside the feeder chamber set to the Spool Gun position.
3.2 Connection of shielding gas
1. Fasten the cylinder and secure it against falling over.
2. Unscrew the cylinder valve momentarily to remove any impurities.
3. Mount the regulator on the cylinder.
4. Connect the regulator with a gas hose (8) on the rear of the welder.
5. Unscrew the cylinder valve and regulator.
3.3 Connection to the mains
1. The device should be used only in single-phase, three-wire power supply system with earthed
zero point.
2. The POCKETMMIG 235 DP inverter recti
fi
er is adapted to cooperate with 230V50 Hz network
protected with 25A fuses with time delay. The power supply should be stable, without voltage
drops.
3.The device is equipped with a power cord and plug. Before connecting the power supply,
make sure that the power switch (6) is in the OFF position.
3.4 Inserting the wire spool
1. Open the side cover of the housing.
2. Make sure the drive rollers are suitable for the type and diameter of the wire. If necessary,
install the correct roller. For steel wires, rolls with V-shaped grooves should be used, and for
aluminum wires with U-shaped grooves.
3. Insert the wire spool onto the mandrel.
4. Secure the spool against falling.
5. Release the feed rollers.
6. Dull the end of the wire.
7. Insert the wire through the feed roller into the holder.
8. Press the wire into the grooves of the drive roller.
9. Unscrew the contact tip from the holder, turn on the power of the welder and pull the wire
into the welder's holder using the quick wire feed function.
10. After the wire appears in the handle outlet, release the button and screw on the contact tip.
11. Adjust the feed roller pressure by turning the pressure knob. Too low pressure will cause the
drive roller to slide, too much pressure will increase the feed resistance, which may lead to wire
deformation and damage to the feeder.
3.5 Preparing the MIG gun for work
Depending on the type of material to be welded and the diameter of the wire, insert the correct
contact tip and wire guide insert into the MIG torch.
For welding steel use steel welding terminals and steel insert. When welding aluminum, use alumi-
num welding terminals and a Te
fl
on insert.
3.5.1 Quick wire feed
The device has a quick wire feed function. Pressing the button (B) causes quick wire feed, en-
abling easy insertion into the holder.
