in this mode. However, the

following  instructions  may

help you achieve 

6- 

If  during  welding  the  arc  tends  to

decrease  excessively,  turn  knob  7  of

Figure fig1 anti-clockwise to reduce the

wire speed, which will also decrease the

weld pool. If, on the other hand, the arc

tends  to  over-lengthen,  turn  the  knob

clockwise. 

7- 

If  there  is  too  much  splatter  while

welding,  the  electronic  inductance

parameter needs to be increased. Do so

turning knob 6 of Figure 1 clockwise.  If

maintaining  an  arc  is  difficult,  turn  the

knob anti-clockwise.

8.3 MMA WELDING

8.3.1 Description

Electric MMA (Metal Manual Arc) and SMAW

(Shielded Metal Arc Welding) are both manual

procedures exploiting the heat generated by

an electric arc that is produced when covered

welding  electrodes  make  contact  with  the

workpiece.   It is commonly used due to its

versatility.  In  fact,  welding  jobs  can  be

performed anywhere: in a workshop, in the

open,  in  confined  spaces  or  hard  to  reach

areas.  A  wide  range  of  electrodes  are

available, 

suiting 

all 

requirements.

The arc is generated touching the electrode

to 

the 

workpiece.

The potentiometer knob (Fig. 1 –8) regulates

the  welding  current  (thicker  workpieces

require higher current settings). 

8.3.2 MMA Welding Features

While welding the following features come into

effect:  

Arc Force: 

Whenever the arc tends to drop

the microprocessor automatically increases

the welding current in order to maintain and

stabilise the arc.

Hot Start:  

The arc is generated touching the

electrode to the workpiece. To ensure the arc

is generated efficiently, the microprocessor

increases the welding current for app. one

second,    guaranteeing  fast,  safe  arc

generation.

Antisticking: 

Decreases the welding current

up to minimum, when the operator makes a

mistake causing the electrode to stick to the

workpiece.  The  electrode  can  be  removed

from  its  clamp  without  causing  damaging

sparks.

8.3.3 MMA Welding

Fig 8 Welding current at the electrode diameter

Proceed as follows for MMA welding: 
1. 

Using  knob  8  (Fig.1)  select  the  welding

current according to the type of electrode and
the thickness of the workpiece. The welding
current value is shown on display panel 13. The
knobs 6 and 7 (fig.1) are disabled.  Guidance
values suitable for various electrode diameters
are provided in Fig 8  

2. 

Connect the earth clamp to the workpiece.

3.

Place the electrode in the clamp. 

4. 

During the entire welding process maintain

a 3-4mm distance from the welding pool that
has been created.  Weld using small zigzag
movements so as to be able to regulate the
size of the weld as desired.

5.

Remove the electrode from the workpiece

to stop welding.
