5.2 Shielding gas connection
1. Secure the cylinder and secure it against tipping over.
2. Open the cylinder valve momentarily to remove any contamination.
3. Install the reducer on the cylinder.
4. Connect the reducer with the gas nozzle (7) on the rear wall of the welder using a hose.
5. Unscrew the cylinder and reducer valve.
5.3 Connection to the mains
1. The device should only be used in a single-phase power supply system,
three-wire, with grounded neutral point.
2. The DIGIMIG 202 M-POWER inverter rectifier is designed to work with a 230V50 Hz network protected
by 25 A delayed fuses. The power supply should be stable, without voltage drops.
3. Before connecting the power supply, make sure that the power switch (6) is in the OFF position.
(off).
5.4 Installing the electrode wire spool
1. Open the side cover of the housing.
2. Check that the drive rollers are suitable for the type and diameter of wire. If necessary, fit the correct
roller. For steel wires, use rollers with V-grooves and for aluminium wires, use rollers with U-grooves.
3. Place the spool of electrode wire on the mandrel.
4. Secure the spool against falling.
5. Release the pressure on the feed rollers.
6. Blunt the tip of the electrode wire.
7. Insert the wire through the feeder drive roller into the holder.
8. Press the wire into the grooves of the drive roller.
9. Unscrew the current tip from the holder, turn on the welding machine power supply and pull the wire into the holder
welding machine by pressing the button on the handle.
10. Once 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 a pressure will result in slipping of
the drive roller, too high a pressure will increase the feeding resistance, which may lead to wire
deformation and damage to the feeder.
