To mount the electrode wire spool, you should:
Twist off the brake sleeve cap (1).
Put on the spool with the wire (2) in such a way to
unwind the spool clockwise.
Make sure if the guide pin has reached the guide
whole of the spool.
Twist on the brake sleeve cap (1).
Make certain if groves of drive rolls are compatible with
thewirediameter.
Insert the electrode wire into the wire feeder.
Drive Roll Replacement
Adjustment of Braking Torque of the
Sleeve
Fig.3
To prevent electrode wire unwinding at the welding
finishing, you should adjust braking torque of the sleeve:
Twist off the brake sleeve cap (1).
To increase the braking torque, you should turn M10 bolt
(2) clockwise.
To decrease the braking torque, you should turn M10
bolt (2) counterclockwise.
Twist on the brake sleeve cap after adjusting finish.
Shielding Gas Connection
To connect shielding gas, you should:

To replace the drive roll you should:
Release the roll pressure arms (5) of the wire drive.
Twist off the roll fastening caps (4).
Take off the drive rolls (3).
Make sure if the key (2) remained in the gear furrow
(1).
Put on the new rolls (3) with diameter and groove
shape adequate for used wire.
Twist on the roll fastening caps (4).
Cut the end of the wire, making sure if there isn’t any
burr.
Insert the wire into the wire feeder as far as EURO
socket (turning the spool clockwise).
Snap the roll pressure arms (5).
Adjust optimum rolls pressure by means of the roll
pressure arm thumbscrew.
After placing the shielding gas cylinder on the platform,
protect it against to overturn with the chain.
Take off the hub cap of the safety valve of the shielding
gas cylinder.
Install the regulator on the gas cylinder.
Connect the regulator to the Magster with gas hose
using band clip.
Welding with CO 2, it is recommended to use the gas
heater. It can be powered from the socket placed on
rear panel.
Controls and Operational Features
Inserting Electrode Wire into the Wire
Feeder
To insert the electrode wire into the wire feeder, you
should:
Match the welding torch with rated parameters
compatible with the power source parameters and
connect it to the EURO socket.
Twist off the nozzle and the contact tip.
Set the WFS control knob in half of the range.
Press the Cold Inch button and hold it until the electrode
wire goes out from the GUN.
Twist on the nozzle and the contact tip again.
