Minarc 150AU / 0411 – 5

Parts of the unit

Body of machine

Main power switch and signal light

Selector switch for welding process

Welding current regulator

Signal light VRD safe ON

Signal light for overheating

Electrode holder and welding cable

Earth cable and clamp

2.5.  CONNECTING TO POWER SUPPLY MAINS

The unit has a mains cable and a wall plug. You can 

fi

 nd fuse and cable sizes in the end 

of these instructions in Technical data.

2.6.  FILLER MATERIALS AND EQUIPMENT

See also 2.4. Main components. You can use all electrodes intended for welding with DC. 
Suitable electrode sizes for the unit are listed in the table on unit’s front panel as well as 
in the end of these instructions in Technical data.

1. 

Use welding speci

fi

 cations given on electrode package.

2. 

Check that you have selected the correct welding process before starting to 
weld.

3. 

Check that welding cable and earth cable connections are tight. If a 
connection is slack, it will result in voltage drop that will cause the 
connection to heat.

4. 

Mount the electrode 

fi

 rmly in holder.

3. USE

It is forbidden to weld in places where there is a danger of 

fi

 re or explosion!

3.1. WELDING 

PROCESSES

3.1.1.  Manual Metal Arc welding (MMA)

In manual metal arc (MMA) the welding 

fi

 ller material is melted from the electrode to the 

weld pool. Filler and rate of welding current is selected on the basis of electrode size used  
and welding position. Arc is formed between electrode tip and work piece. The melting 
electrode coating forms gas and slag, which protects the weld pool. Slag solidi

fi

 ed over 

the weld is removed after welding e.g. with a chipping hammer.
