Instructions For Use; Electrode Welding (Mma) - CEA MATRIX 2800 E Manuel D'instructions

Connect a suitable load of normalised plug (3p+t) to the
power cable and provide for an electrical socket complete
with fuses or an automatic switch. The ground terminal
must be connected to the ground conducting wire (YEL-
LOW-GREEN) of the supply.
Table 2 shows the capacity values that are recommended for
fuses in the line with delays.

mation on the control panel, see the instruction man-
ual enclosed.

Electrode welding (MMA)

Electrode welding is used for welding most metals (various
types of steels, etc.) using rutilic, basic, and cellulosic elec-
trodes with diameters from Ø 1,6 mm to Ø 5,0 mm.
1) Connecting the welding cables (Fig. B):
Disconnect the machine from the mains power supply and
connect the welding cables to the output terminals (Positive
and Negative) of the welding machine, attaching them to
the clamp and ground with the polarity specified for the type
of electrode being used (Fig.B). Always follow the electrode
manufacturer's instructions. The welding cables must be
as short as possible, they must be near to one another, po-
sitioned at or near floor level. Do not touch the electrode
clamp and the ground clamp simultaneously.
2) Switch the welding machine on by moving the power sup-
ply switch to I (Pos. 5, Fig. A).
3) Make the adjustments and select the parameters on the
control panel (for further information see the paragraph in
the manual for the MX control panel).
4) Carry out welding by moving the torch to the workpiece.
Strike the arc (press the electrode quickly against the met-
al and then lift it) to melt the electrode, the coating of which
forms a protective residue. Then continue welding by mov-
ing the electrode from left to right, inclining it by about 60°
compared with the metal in relation to the direction of weld-
ing.
