Install the gas regulator on the gas cylinder.
Connect the shielding gas cylinder to the wire feeder
with the gas hose of the combined cable, using
clamping band.
Welding with CO

as shielding gas, you should use
the gas heater which can be supplied from the
socket on the rear panel of the welder.
Controls and Operational Features
1. Power Switch: Turns the machine on/off. Switching
on is indicated by lighting up of the switch button.
2. Welding Voltage Changing Switch: 3-step switch
enables welding voltage step selection.
WARNING
It is not allowed changing the welding voltage range
during welding process. It may damage the switch.
3. Welding Voltage Changing Switch: 10-step switch
enables welding voltage step selection.
WARNING
It is not allowed changing the welding voltage range
during welding process. It may damage the switch.
4. Output Socket with High Inductance: For connecting
the ground cable. The high inductance connection is
more suitable for short arc welding in heavier work
or when using mix Ar+CO
2
shielding gas.
5. Output Socket with Low Inductance: For connecting
the ground cable. The low inductance connection is
typically used for short arc welding of mild steel,
particularly on thin materials or when using CO
2
shielding gas.
6. Positive Output Socket: For connecting the welding
cable to the wire feeder.
7. Control Socket: 7-pin socket for connecting the
control cable to control the welding source and to
supply the wire feeder from the welding source.
8. Quick Water Connector of the Cooling System:
For connecting hoses of the water cooling system.
(Magster 450W only).
Rear Panel
1. Bracket: for fastening the gas cylinder.
