9. MMA coated electrode welding
Connect the device to the 230 V mains using cable 9 (Fig. 1).
Connecting the wires to the MMA electrode welding
- Connect the ground wire plug to the 8 (-) socket on the device
- Connect the plug of the electrode holder to socket 5 (+) on the device.
ATTENTION:
Some coated electrodes require reverse polarity - see instructions
on the electrode packet. Switch on the unit with 1 ON / OFF switch.
Starting the welding mode with the electrode is carried out by pressing button 5 -
indicator 8 lights up (See chapter 7 - Fig. 2).
ATTENTION:
Avoid accidentally touching the end of the electrode with the workpiece,
as the welding current is still present in the cables. After switching the device on (ON),
set the proper welding current for the given electrode diameter with the knob (1) (see
instructions on the electrode packet). The value of the welding current is shown in
display 1 (the indicator 25 lights up continuously).
The electric arc is initiated by rubbing the end of the electrode with the base material (connected
with the device by earth cable), and after the arc occurs, it is necessary to quickly move
the tip to a certain distance.
If the tip of the electrode is removed too quickly, the arc will be torn off and alternatively, moving
too slow can result in creating short circuit and sticking the end of the electrode to the material.
Select MMA welding (indicator 8 ) by pressing the welding mode selection button 5. There is no-load
voltage at both output terminals (ground clamp and electrode holder).
In the MMA welding mode, the voltage indicator 25 is permanently on.
Select the welding current setting 13 by pressing the welding parameter selection button 2 and adjust
welding current for the MMA using knob 4 . Welding current may be changed during welding work.
