7.7 Welding MMA
The device described in this guide is able to weld with coated electrodes hot melt.
To weld MMA, select on the control panel function MMA.
After selecting the MMA can immediately adjust the welding current. Adjustment is done by turning the knob
"Welding current".
Values ​​for welding current, the polarity of, the requirements of the drying usually given by manufacturers of
electrodes on the packaging.
In the current slot (plus and minus) to plug welding wires.
Ground wire hook to the work piece, the wire electrode wear electrode.
To avoid splashes during welding and to obtain good quality welds, must comply with the instructions given
by the manufacturer of the electrodes: welding current, welding positions, time and drying temperature. This
is of particular importance in the case of electrodes of alkaline or acidic buffer zone (EB, EA)
The basic parameters of the welding MMA:
-
welding current,
